Background: Many veterinarians consider English Bulldogs to have a greater perianesthetic mortality risk. The aims of this study were to 1) determine total and anesthesia-related, perianesthetic mortality (PAM) rates in English Bulldogs (EB), 2) identify potential risk factors associated with mortality in EB, and 3) determine the difference in the perianesthetic mortality rates between EB, other-brachycephalic breeds (OB), and non-brachycephalic breeds (NB). Records from EB that were anesthetized between 2010 and 2017, were investigated. OB and NB were enrolled to match with each EB based on a procedure and age from the study period. Data collected in EB included: age, ASA status, weight, procedure types, anesthetic and analgesic management, anesthetic duration, anesthetic recovery location, and cause of death. Age and cause of death were determined from OB and NB. Fisher's exact test was used to compare PAM rate and age in EB, OB, and NB. Mann–Whitney U test was used to compare EB survivor and EB non-survivor. Logistic regression models were used to identify factors and odds ratio (OR) associated with PAM in EB. Result: Two hundred twenty nine EB, 218 OB, and 229 NB were identified. The total and anesthesia-related PAM rates in EB were 6.6 and 3.9%, respectively. EB had a greater total PAM rate compared with OB (p = 0.007). ASA status was different between survivors and non-survivors in EB (p < 0.01). Risk factors identified regardless of the cause of death were premedication with full μ opioids (OR = 0.333, p = 0.114), continuous infusion of ketamine post-operatively (OR = 13.775, p = 0.013), and acepromazine administration post-operatively (OR = 7.274, p = 0.004). The most common cause of death in EB was postoperative respiratory dysfunction (87.5%). Conclusion: Total and anesthesia-related mortality in EB is considerable. Most deaths in EB occurred during the postoperative period secondary to respiratory complications. [ABSTRACT FROM AUTHOR]

A case of a nine-year-old, intact female, American Bulldog with a heart mass is described. Echocardiography was used to identify this pathological lesion. Part of the mass and pericardial sac were surgically removed for histopathological examination. A final diagnosis of neuroendocrine carcinoma was diagnosed by necropsy and histopathology. To the author’s knowledge, there is very limited information in the literature about this pathology. [ABSTRACT FROM AUTHOR]

Introduction: Hermaphroditism is less frequently reported in dogs and is often associated with infertility. Case report: An 8‐month‐old French bulldog weighing 5 kg with an enlarged structure protruding from the vulva was clinically diagnosed with hermaphroditism. Physical, hormonal assay, computed tomography, and gross and histological studies were done in addition to successfully detailed surgical correction. On physical examination, the dog showed the presence of an os‐clitoris protruded from the vulvar labia. Hormonal levels of estradiol, testosterone, and progesterone were 6.39 pg/ml, 0.4 ng/ml, and 8.67ng/ml, respectively. Surgical removal of internal gonadal tissues and os clirectomy operations were conducted after the exploratory laparotomy. The removed gonadal tissues were identical to that of a female with testicles instead of ovaries, according to a gross examination. Histological examination confirmed gonads as testis, with inactive seminiferous tubules and epididymis attached to uterine horns. Conclusion: The congenital anomalies in the present case were diagnosed as male pseudohermaphroditism (MPH). Surgical correction was performed, and the owner's satisfaction was achieved.

Objectives: To present the prevalence and distribution of heart disease as well as echocardiographic findings in English Bull Terriers. Materials and Methods: One hundred and one English Bull Terriers were retrospectively included to evaluate the prevalence and distribution of heart disease. Secondly, a retrospective study on mitral valve abnormalities was performed on three groups: a control group (n=120, 19 breeds) used to establish reference intervals for mean transmitral gradient; a healthy English Bull Terriers group (n=25) and an English Bull Terriers group with mitral valve abnormalities (n= 18). Healthy English Bull Terriers for which mitral inflow parameters were not obtainable and English Bull Terriers with other types of heart disease were excluded. Results: The prevalence of heart disease in English Bull Terriers was 65% (66/101), with mitral valve abnormalities (47%, 47/101) and aortic stenosis (29%, 29/101) being most common. The cut‐off value for normal mean transmitral gradient was 3.5 mmHg in the control group. The mean transmitral gradient for healthy English Bull Terriers was higher than for other dog breeds. Healthy English Bull Terriers had a smaller mitral valve area and mitral annulus diameter compared with dogs with a similar body surface area. A high heart rate, smaller mitral valve area, mitral regurgitation, and volume overload are associated with increased mean transmitral gradient in English Bull Terriers with mitral valve abnormalities. Clinical Significance: We suggest that mitral valve area, mitral annulus diameter and mean transmitral gradient measurements should be included in the echocardiographic protocol for English Bull Terriers.

[Display omitted] • The network of interactions showed low modularity and core-periphery organization. • Male bat individuals with greater body mass played an important role in the network. • High abundance of Paradyschiria parvula defined core individuals in the network. • The presence/abundance of Paradyschiria and Noctiliostrebla are benefited by each other. • Individual-level network is a useful tool to understand parasite transmission. Individual-based networks provide the building blocks for community-level networks. However, network studies of bats and their parasites have focused only on the species level. Intrapopulation variation may allow certain host individuals to play important roles in the dynamics of the parasites. Therefore, we evaluated how the variation in host sex, body size, ectoparasite abundance and co-occurrence configure individual-based networks of the lesser bulldog bat Noctilio albiventris and bat flies. We expected bat individuals with greater body mass and forearms acting as the core in the network. We also expected males to play a more important role in the network. We sampled a network of N. albiventris bat individuals and their bat flies to describe the structure of an antagonistic individual-based network. We aimed to identify the most relevant bat individuals in the network, focusing on the implications inherent to each of the following approaches: (i) core-periphery organization; (ii) modularity; (iii) species level metrics; and (iv) the main ecological driver of bat individual roles in the network, using niche-based predictors (body mass, forearm and sex). We showed that a network of N. albiventris individuals and their bat flies had low modularity containing a persistent nucleus of individuals and bat flies with well-established interactions. Male individuals with greater body mass played an important role in the network, while for females neither mass nor forearm length were important predictors of their role in the network. Finally, individuals with a high abundance of Paradyschiria parvula played a core role. These results provide an alternative perspective to understand the patterns and mechanisms of interspecific interactions between parasites on the host, as well as sex-biased parasitism.

Objective: The aim of this retrospective study was to review the clinical data and outcomes of patients that suffered ectopic cilium (EC). Animals studied: One hundred and twelve dogs from multiple private practices in France, with a clinical diagnosis of EC were included in the study. Results: The mean age of affected dogs was 2.3 years. There were 64 females and 48 males. The most represented breeds were the Shi Tzu, the French Bulldog, the English Bulldog and the Chihuahua. Eleven dogs were affected bilaterally. The upper eyelid was implicated in 93.5% of the cases, with the median portion being the most affected. No statistical difference was observed between the right and the left eye. EC were associated with distichiasis in 50% of the cases. Pigmentation of the conjunctiva at the point of exit of the EC was present in 58% of the cases. EC were short in 75% and long in 25% of the cases. Corneal complications were statistically associated with short EC. The corneal lesions associated with EC were keratitis (94%), corneal granuloma (0.8%), corneal fibrosis (2.7%), corneal degeneration (0.8%), superficial corneal ulcer (68.7%), deep corneal ulcer (8%) and perforating corneal ulcer (0.8%). The surgeries which consisted of the removal of the hair follicle was successful in 88.4% of the cases. Conclusion: EC is a rare condition which can be treated successfully by the removal of the hair follicles. It must be suspected in cases of corneal lesions unresponsive to medical treatment.

Background: The relationships among gastric lymphoid follicular hyperplasia (GLFH), Helicobacter‐like organisms (HLOs), and clinical signs have not been established in dogs. Objectives: To evaluate the epidemiologic, clinical, endoscopic, and histopathologic findings associated with GLFH in dogs, and determine the association of GLFH with HLOs and the French Bulldog (FB) breed. Animals: Two hundred eighty‐eight dogs that underwent gastroscopy between 2013 and 2016. Methods: Retrospective, cross‐sectional study. Gastric biopsy samples were reviewed and scored for inflammation and HLOs. Dogs were divided into 3 groups: group 1 (63 FBs), group 2 (45 non‐FB brachycephalic dogs), and group 3 (180 nonbrachycephalic dogs). Variables were evaluated for their association with GLFH. Results: Univariate analysis determined that intact males, young age, vomiting, gastroscopic findings (discoloration, hemorrhage, and ulcers), and histopathologic findings (gastric lamina propria lymphocytic infiltration and HLO score) were associated with GLFH (P ≤.03). In the multivariate analysis, GLFH was associated with the HLO score (odds ratio [OR] > 5 for HLO scores 1‐2 and >15 for HLO score of 3; P <.001), with vomiting (OR > 4; P =.01) but not with FB breed (P =.76) and age (P =.1). The HLO score was associated with younger age (P <.001). Conclusion and Clinical Importance: The HLO score was associated with a high GLFH score. Vomiting was associated with GLFH. Helicobacter‐like organisms are highly prevalent in young dogs and GLFH is indirectly associated with this factor. Clinical relevance of the identification of GLFH and HLO remains to be determined.

CASE DESCRIPTION A 4-month-old 5.9-kg sexually intact female French Bulldog was presented because of recurrent urinary tract infections in combination with pollakiuria, hematuria, and urinary ncontinence. CLINICALFINDINGS A diagnosis of malakoplakia was made on the basis of results of hematologic and serum biochemical testing, abdominal ultrasonography, bacterial culture, and cystoscopic biopsies of the urinary bladder wall. Biopsy samples were sent for routine histologic examination and fluorescence in situ hybridization to confirm the presence of intracellularand subendothelial bacteria. TREATMENTANDOUTCOME Treatment with enrofloxacin was started after the diagnosis of malakoplakia was confirmed. During treatment, polypoid changes in the urinary bladder decreased dramatically but did not disappear. On follow-up ultrasonography after 12 weeks of treatment, marked improvement was visible and results of repeated bacterial culture and fluorescence in situ hybridization of bladder wall samples were negative. The patient was free from clinical signs and had an ultrasonographically normal urinary bladder 59 weeks after antimicrobial treatment was discontinued. CLINICALRELEVANCE Malakoplakia, a granulomatousdisease characterized by impaired histiocytesthatare unable to completely digest phagocytized bacteria, is a very rare d isease in dogs, but early suspicion of the condition is essential toallow timely diagnosisand avoid disease progression andthe need forprolonged treatment. Malakoplakia should be considered in young dogs with chronic urinary tract infections; the diagnosis can be made through a combination of histologic examination and fluorescence in situ hybridization of bladder wall biopsy samples.

A 5‐year‐old male, neutered, English Bulldog presented for acute progressive paraparesis. Neurological examination revealed a weak withdrawal reflex in the left pelvic limb and lumbosacral pain, suggestive of a L4–S3 myelopathy. Magnetic resonance imaging revealed an incidental intramedullary mass at the T9 vertebra and L7–S1 intervertebral disc protrusion with bilateral foraminal stenosis. The dog was treated with epidural methylprednisolone. Repeat neurological examination postepidural revealed normal withdrawal reflexes and resolution of lumbosacral spinal pain. However, progressive paraparesis, thoracolumbar pain and epaxial muscle atrophy were evident. A T3–L3 myelopathy was suspected secondary to the intramedullary mass. The mass was surgically resected, and histology revealed haemangioblastoma. Neurological status improved initially, but deteriorated later due to the lumbosacral disease. The dog improved following repeat methylprednisolone epidural injection, but remained paraparetic. This case report is consistent with previous literature and provides additional information on the treatment and prognosis of spinal cord haemangioblastoma with concurrent lumbosacral disease.

A 6‐month‐old male Old English Bulldog with tetralogy of Fallot (ToF) required general anaesthesia for surgical palliative treatment of ToF, whereby a shunt was placed between the left subclavian artery and the pulmonary trunk to increase pulmonary circulation (modified Blalock‐Taussig shunt). Anaesthesia of a patient with ToF presents an anaesthetic challenge given the four concurrent cardiac defects as well as the surgical manoeuvres involved, requiring an advanced understanding of the underlying pathophysiology and haemodynamics. Besides this, a thorough knowledge of the clinical effects of anaesthetic events and drugs is required. This case report describes the two major anaesthetic events that occurred and the unexplained hyperkalaemia that developed. Furthermore their management is explained and discussed.

A 3‐year‐old French bulldog was presented with a 2‐year history of a progressively worsening stertor and exercise intolerance. Clinical examination was suggestive of brachycephalic obstructive airway syndrome (BOAS). Routine laryngeal examination and computed tomography confirmed changes consistent with BOAS. A folded flap palatoplasty and vertical wedge resection alarplasty were performed. Severe dyspnea and cyanosis developed during recovery necessitating emergency intubation, and temporary tracheostomy was performed. A silicone tracheal stoma stent was placed instead of a tracheostomy tube. The silicone stoma stent was removed after 48 hours, and the patient remained hospitalised for observation for further 8 hours. Before discharge, the patient became severely distressed during IV canula removal. Rapid onset of severe subcutaneous emphysema and dyspnea necessitated emergency induction and intubation. Thoracic radiographs revealed a left‐sided pneumothorax. Following thoracostomy tube placement and drainage, a permanent tracheostomy was performed and the dog was discharged from hospital the following day. [ABSTRACT FROM AUTHOR]

Background: Tracheal narrowing due to congenital tracheal hypoplasia, acquired tracheal stenosis and tracheal collapse can lead to life-threatening respiratory distress. Tracheal hypoplasia has been identified in brachycephalic dog breeds, predominantly English Bulldogs, by measuring the tracheal diameter compared to the diameter of the thoracic inlet and creating a ratio. However, reference ranges for tracheal diameter have not been established for non-brachycephalic small breed dogs. It would be advantageous to have established tracheal diameters for non-brachycephalic small breed dogs, as these are the dogs most at risk of tracheal collapse. The main objective, of this study was to radiographically evaluate vertical tracheal diameter (VTD) at three standardized locations along the trachea of non-brachycephalic small breed dogs, in an attempt to further establish a screening diagnostic protocol for canine tracheal hypoplasia. Medical records and thoracic radiographs of non-brachycephalic small breed dogs without respiratory disease were reviewed. Right lateral radiographs were reviewed. The absolute and average VTDs at three locations (location A: caudal cervical VTD; location B thoracic inlet VTD; location C: intrathoracic VTD) were standardized by manubrium length (ML), as well as by the previously utilized thoracic inlet distance (Ti-D) and proximal 3rd rib width (PR3-W) to calculate manubrium-tracheal index (M-TI), thoracic inlet-tracheal index (Ti-TI), and proximal R3-tracheal score (PR3-TS), respectively. Correlations between averaged tracheal diameter and each of the ML, Ti-D, and PR3-W, and between M-TI and each of Ti-TI and PR3-TS were calculated. Results: Eighty-one healthy dogs met the criteria for inclusion. Significant differences (P < 0.0001) were identified among the mean values of the absolute and standardized VTDs at levels A, B, and C. The smallest tracheal diameter was identified at the level of the thoracic inlet (Level B). The average VTD correlated better with ML (rs = 0.82, P < 0.0001) compared to Ti-D and PR3-W. A relatively strong correlation (rs = 0.77, P < 0.0001) was identified between the averaged manubrium tracheal index (M-TI) and thoracic inlet tracheal index (Ti-TI). Conclusion: M-TI is an appropriate alternative to Ti-TI and PR3-TS to radiographically evaluate VTD in dogs. M-TI < 0.43, < 0.34, or < 0.38 at level A, B, or C, respectively, may indicate tracheal hypoplasia in non-brachycephalic small breed dogs. Screening of canine VTD could be achieved using M-TI.

A young French Bulldog was presented with clinical signs of chronic gastrointestinal disease, unresponsive to medical therapies. Parasite screenings and abdominal ultrasound failed to identify the etiology of the clinical signs. Cytologic evaluation of a rectal scraping sample diagnosed presumptive granulomatous colitis (GC) based on the presence of numerous macrophages with characteristic abundant, pink, granular cytoplasm, which showed an intense pink color when stained with periodic acid‐Schiff. Tissue biopsy samples and Escherichia coli fluorescence in situ hybridization analysis confirmed the cytologic diagnosis. The cytologic, histopathologic, and clinical features and staining properties of GC in a French Bulldog are reported. Rectal scraping should be considered a part of the diagnostic evaluation in patients with suspected GC. [ABSTRACT FROM AUTHOR]

Background: Prolapsed nictitating membrane gland (PNMG) is the most common disorder of the third eyelid in dogs. However, the epidemiology of PNMG in the wider dog population remains understudied. Methods: Using de-identified clinical data from the VetCompass Programme, this cohort study aimed to report the prevalence, demographic and breed-related risk factors of PNMG in dogs attending UK primary care veterinary practices in 2016. Results: There were 1,802 PNMG cases identified from 905,543 dogs, yielding an annual prevalence of 0.20% (95% confidence interval (CI) 0.19–0.21). The median age at first diagnosis was 0.63 years (IQR 0.33–1.98, range 0.11–18.00). Dogs aged under 1 year had 10.82 times the odds (95% CI 9.17–12.76) compared with dogs aged from 2 to under 4 years. Neutered animals had higher odds than entire animals within both sexes. Breeds with the highest odds of PNMG compared with crossbred dogs included Neapolitan Mastiff (odds ratio (OR) 34.26, 95%CI 15.92–73.75), English Bulldog (OR 24.08, 95% CI 20.62–28.13), Cane Corso (OR 14.66, 95% CI 8.18–26.28), Lhasa Apso (OR 12.37, 95% CI 10.26–14.92) and American Cocker Spaniel (OR 11.57, 95% CI 5.59–23.96). Purebred dogs had 1.43 times the odds (95% CI 1.26–1.63) of PNMG compared with crossbreed dogs. Breeds with brachycephalic skull conformation had 6.71 times the odds (95%CI 5.89–7.64) compared with breeds with mesocephalic skull conformation. Insured dogs had 1.89 times the odds (95% CI 1.65–2.16) compared with uninsured dogs. Conclusions: This study reports the largest cohort of primary-care PNMG cases assembled to date. The results showing young age at diagnosis along with the breed, purebred and brachycephalic skull conformation predispositions suggest a hereditary involvement in PNMG development. These results may help to guide breeding strategies to reduce the prevalence of PNMG and improve welfare in predisposed individuals. [ABSTRACT FROM AUTHOR]

Prostatic cysts are fluid-filled structures located adjacent to the prostate gland. Clinical expression is often asymptomatic, rarely tenesmus, lethargy, anorexia, and hematuria occur.Paraprostatic cysts are more common in uncastrated dogs over 8 years of age, without a predisposition to breed. These fluid-filled cysts are often localized or extend from the outer edges of the prostate.The research took place between 2017-2020 on 23 dogs of different breed and age, within the Clinic of the Faculty of Veterinary Medicine Bucharest and within the private veterinary practices. The diagnosis of paraprostatic cysts was established in 7 dogs age 1-5 years (n = 1), 5-10 years (n = 2), 10-15 years (n = 4), of different breeds.The reason for the presentation at the clinic was the observation by the owners of the tendency to constipation (n = 5), dysuria (n = 2) and a urination with blood (n = 3). Ultrasound identification of cystic formations with paraprostatic localization highlighted the existence of cystic formations with dimensions of 20 mm (n = 4), 70 mm (n = 2) and 3.8 cm (n = 1). In the mass of the prostate glandular parenchyma, cystic dilatations were identified, with an anechoic content with rare corpuscular elements in suspension (n = 3) and cellularity (n = 4), accompanied by ultrasound specific artifact distal enhancenment. Intraprostatic cysts were found in 16 dogs age 1-5 years (n = 3), 5-10 years (n = 5), 11-15 (n = 5) and 16-20 years (n = 3), common breed (n = 6), German Shepherd (n = 3), pointer (n = 1), English Bulldog (n = 1) Dachshund (n = 1), Afghan Greyhound (n = 1) and West Highland White Terrier (n = 3). The reason for presenting to the doctor was dysuria (n = 5) and hematuria (n = 7), or routine ultrasound examination. Ultrasonography detected single, multiple or scattered cystic formations of round / ovoid type with a fine echogenic wall clearly delimited by the rest of the parenchyma of infracentimetric dimensions (n = 12) centimeters in 4 dogs, with clearly homogeneous and anechoic content, accompanied by the distal enhancement.

Background: Brachycephalic obstructive airway syndrome (BOAS) is common in brachycephalic breeds and comprises multiple anatomic characteristics. Computed tomography (CT) is increasingly used in the preoperative assessment of dogs presenting with BOAS. We describe the case of a French Bulldog with a presumed congenital hyoid malformation and anatomic comparison of hyoid morphology between French Bulldogs and mesaticephalic dogs using CT. Methods: Skull CT studies of French Bulldogs and mesaticephalic dogs presenting to two referral hospitals between 2013 and 2020 were collected. The degree of curvature of the basihyoid bone and the relative ventrodorsal thickness (RVD) were determined using a novel measurement technique. A circle of best fit was applied to the inside arc of the basihyoid bone, and the radius and sector angle within the basihyoid bone were recorded. The RVD was defined by the ventrodorsal thickness divided by the width in the frontal plane. Results: The basihyoid bone of French Bulldogs had a greater mean ± SD RVD of 0.23 ± 0.04 compared to 0.16 ± 0.03 in mesaticephalic dogs (P < 0.01). The sector angle was also greater in French Bulldogs, measuring 144.08 ± 20.88° compared to 103.94 ± 16.49° in mesaticephalic dogs (P < 0.01). Conclusion: This case of hyoid malformation in a French Bulldog reports a rarely documented condition that complicated the management of BOAS. Comparative assessment of hyoid conformation revealed more acute curvature and greater RVD in French Bulldogs than in mesaticephalic dogs. This may represent an additional distorted anatomic component of brachycephalic skull morphology. [ABSTRACT FROM AUTHOR]

It mentions that MRI Iesions consistent with PC were common in epileptic dogs.

Background: The French Bulldog is a highly popular dog breed but is linked with many serious health issues. A holistic view of breed health in French Bulldogs would assist efforts to appreciate the overall health strengths and weaknesses in the French Bulldog and to take appropriate steps to mitigate these. Based on random sampling of French Bulldogs and non-French Bulldogs under primary veterinary care during 2016 within the VetCompass Programme, a cohort study design was used to estimate the one-year (2016) period prevalence of the most commonly diagnosed disorders in each group. Risk factor analysis used multivariable logistic regression modelling methods. Results: The analysis included 2,781 French Bulldogs and 21,850 non-French Bulldogs. French Bulldogs were younger (1.51 years, IQR 0.86 – 2.77 vs. 4.48 years, IQR 1.94 – 8.14) (p < 0.001) and lighter (12.45 kg, IQR 11.00 – 14.03 versus 13.80 kg, IQR 8.10 – 25.12) (p < 0.001) than non-French Bulldogs. Of 43 common specific-level disorders across both groups, French Bulldogs had significantly increased adjusted odds of 20/43 (46.5 %) disorders and significantly reduced adjusted odds of 11/43 (25.6 %) disorders compared to non-French Bulldogs. Highly predisposed disorders in French Bulldogs included stenotic nares (OR 42.14; 95 % CI 18.50 to 95.99; p < 0.001), Brachycephalic Obstructive Airway Syndrome (OR 30.89; 95 % CI 20.91 to 45.64; p < 0.001), aural discharge (OR 14.40; 95 % CI 9.08 to 22.86; p < 0.001), skin fold dermatitis (OR 11.18; 95 % CI 7.19 to 17.40; p < 0.001) and dystocia (OR 9.13; 95 % CI 5.17 to 16.13; p < 0.001). At a grouped-level of diagnostic precision, French Bulldogs had increased adjusted odds of 12/32 (37.5 %) disorders and reduced adjusted odds of 6/32 (18.8 %) disorders compared to non-French Bulldogs. Conclusions: These results identified ultra-predispositions with worryingly higher odds in French Bulldogs for several disorders, suggesting that the health of French Bulldogs has diverged substantially from, and may be lower than, the health of the wider non-French Bulldog population. Many of these predispositions are closely associated with the conformational extremes that define the French Bulldog breed. Shifting the typical conformation of the French Bulldog population towards a more moderate phenotype is proposed as a logical opportunity to reduce the serious health issues endemic in the French Bulldog breed. Plain English Summary: The French Bulldog is currently a hugely popular dog breed in the UK. However, the breed is linked with a range of serious health issues. Using veterinary clinical data from the VetCompass Programme at the Royal Veterinary College, this study aimed to compare the frequency of common disorders in French Bulldogs against that of all remaining dogs to identify health strengths and weaknesses in French Bulldogs. This overall view of breed health can assist owners, breeders and veterinarians to take appropriate actions to improve the health of French Bulldogs. From an overall population of 905,544 dogs, random samples of 2,781 French Bulldogs and 21,850 non-French Bulldogs were included in the analysis. French Bulldogs were younger (1.51 years versus 4.48 years) and lighter (12.45 kg versus 13.80 kg) than non-French Bulldogs. French Bulldogs had increased risk of 20/43 (46.5 %) specific disorders and decreased risk of 11/43 (25.6 %) specific disorders compared to non-French Bulldogs. The disorders with greatest relative risk in French Bulldogs compared to non-French Bulldogs were narrowed nostrils (x 42.14), Brachycephalic Obstructive Airway Syndrome (x 30.89), ear discharge (x 14.40), skin fold dermatitis (x 11.18) and difficulty giving birth [dystocia] (x 9.13). When the disorders were grouped into broad disease categories, French Bulldogs had increased risk of 12/32 (37.5 %) disorder groups and reduced risk of 6/32 (18.8 %) disorder groups compared to non-French Bulldogs. This study suggests that the health of French Bulldogs is very different, and largely much poorer, that the health of the wider non-French Bulldog population. Many of these differences are closely associated with the extreme body shape that defines the French Bulldog breed. Shifting the body shape of French Bulldogs to become more moderate, and hence less extreme, is proposed as a logical opportunity to reduce the current serious and common health issues in the French Bulldog breed.

Background: Respiratory distress is one of the most common afflictions of brachycephalic dogs. Dogs in respiratory distress usually present to the emergency service with a constellation of clinical signs including but not limited to: stertorous breathing, dyspnea, gagging, cyanotic mucus membranes, hyperthermia, and commonly a history of gastrointestinal signs. While Brachycephalic Obstructive Airway Syndrome is the most common cause of respiratory distress in dogs with brachycephalic conformation, any condition eliciting an inflammatory response in the oropharynx, can result in obstruction. There is no previous report of respiratory obstruction leading to emergency tonsillectomy caused by tonsillar polyps. Case presentation: A 9-month-old male intact English bulldog presented to the emergency service in severe respiratory distress. Due to continued severe dyspnea and cyanosis the patient was induced with propofol (Propofol, Hospira) 4 mg/kg intravenously titrated to effect and tracheal intubation performed. Intubation was noted to be difficult due the presence of two, large, inflamed masses in the oropharynx region. The remainder of his physical exam was unremarkable. Minimum database blood work and chest radiographs revealed only minor abnormalities. The patient was placed under anesthesia and the masses were transected sharply using a carbon dioxide (CO2) laser (Aesculight, Bothell, WA, USA). Anesthesia and recovery were uneventful, and the patient was discharged the following day. Histopathology results of the masses revealed them to be benign lymphoglandular polyps. Conclusions: This is the first report of bilateral tonsillar polyps causing life-threatening respiratory obstruction in a dog. Both masses were excised safely and completely with the CO2 laser. Difficulties inherent to oropharyngeal surgery include the hemorrhage, small working space, tissue swelling and difficult visualization. Surgical excision of these polyps alleviated all emergent and chronic clinical signs, and the patient's remains healthy 12-months post-treatment. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the frequency of ophthalmic disorders in 7 brachycephalic dog breeds referred to an academic veterinary ophthalmology service. Animals: 970 client-owned dogs of 7 brachycephalic breeds that were evaluated by the ophthalmology service in a veterinary teaching hospital from January 2008 through December 2017. Procedures: Medical records of 7 brachycephalic breeds (ie, Boston Terriers, English Bulldogs, French Bulldogs, Lhasa Apsos, Pekingese, Pugs, and Shih Tzus) were reviewed to collect data regarding patient signalment, ophthalmic diagnoses, affected eyes, and number and dates of visits. Results: Median age at the first examination was 7 years (range, 23 days to 22 years). The number of dogs seen for a first examination increased with age. Corneal ulcers, keratoconjunctivitis sicca, corneal pigmentation, immature cataracts, and uveitis were each diagnosed in ≥ 100 dogs and represented 40.4% (1,161/2,873) of all diagnoses. On the basis of anatomic location, 66.3% (1,905/2,873) of all disorders were located in either the cornea (1,014/2,873 [35.2%]) or adnexa (891/2,873 [31%]). There was a significant difference in breed proportion in the study population; of the 7 breeds studied, Shih Tzus (34.3% [333/970]), Pugs (20.8% [202/970]), and Boston Terriers (16.6% [161/970]) were the most prevalent breeds. The frequency of some diseases within the referral population was associated with breed. Conclusions and clinical relevance: Findings suggested that the most prevalent disorders for the brachycephalic breeds in this ophthalmic referral population were corneal ulcers, keratoconjunctivitis sicca, corneal pigmentation, immature cataracts, and uveitis.

Postoperative upper airway obstructions in brachycephalic dogs (BDs) mainly occur following brachycephalic airway surgery. Tracheostomy is the most frequently reported technique to relieve upper airway obstructions. A 10‐year‐old French bulldog presented repeated regurgitation during anaesthesia for orthopaedic surgery. Oesophageal and pharyngeal lavage were performed. Seven hours after recovery, the dog displayed severe stertor and hypoxemia, which were not relieved with oxygen flow‐by and sedation. Emergency anaesthesia and tracheal intubation were performed. Laryngoscopy revealed severe pharyngeal inflammation. A nasotracheal tube (NTT) was placed while the dog remained intubated, and diluted adrenaline was sprayed on the pharynx using a mucosal atomization device. Mild sedation and oxygenotherapy through NTT were maintained for 3 days. The dog was discharged after 5 days. This report describes an uncommon complication of perianaesthetic repeated regurgitation in a BD, and an unusual technique for managing an upper airway obstruction. [ABSTRACT FROM AUTHOR]

A frameshift deletion variant in the Wnt pathway gene dishevelled 2 (DVL2) is associated with a truncated, kinked tail ("screw tail") in English Bulldogs, French Bulldogs and Boston Terriers. These breeds are also characterized by distinctive morphological traits, including a wide head, flat face and short-limbed dwarfism, which are characteristic of Robinow syndrome in humans, caused by defects in genes such as DVL1 and DVL3. Based on these phenotypic and genetic similarities, it has previously been hypothesized that the canine DVL2 variant results in a syndromic phenotype called the Robinow-like syndrome. In our study, we investigated the distribution of the DVL2 variant in 1954 dogs from 15 breeds, identifying breeds with allele variation and enabling the dissection of the genotype–phenotype correlation for the first time. With CT examinations in American Staffordshire Terriers, we confirmed that the DVL2 allele is associated with caudal vertebral malformations and a brachycephalic phenotype. We also hypothesize that the variant may be linked to additional health conditions, including brachycephalic obstructive airway syndrome and congenital heart defects. Altogether, our study strengthens the role of DVL2 as one of the contributors to the "bulldog type" morphology and features on the spectrum of human Robinow syndrome. [ABSTRACT FROM AUTHOR]

The aim of this case report is to present a case where it was used hydrodissection to remove a 360° conjunctival flap° from a dog. A 2 year old, male french bulldog weighting 18 kg was taken to a veterinary service with a 360° conjunctival flap in its left eye due to a previous treatment of an extensive melting ulcer for the past 40 days. After performing routine preoperative exams, a new surgical procedure was performed to remove the flap. The technique of choice was hydrodissection, which consisted of injecting 2 mL of 0.9% sodium chloride under conjunctival flap, followed by the divulsion, releasing the conjunctiva from its corneal bed with the use of iris scissors until complete removal of the tissue. The patient showed excellent postoperative recovery, with decreased corneal scarring and no inflammation of the conjunctiva over 3 months of post op evaluation. The hydrodissection technique has facilitated the removal of the 360° conjunctival flap in this present case, making it a potential technique of choice in other similar procedures.

The strong odour of faeces and excessive production of gases in some dog breeds have long been a concern of owners. The pet food industry uses nutritional alternatives, such as high‐quality ingredients and additives, to improve the odour of faeces. However, there are still some dog breeds, such as the French Bulldog, that present this problem due to the presence into the large intestine of indigested protein. Therefore, a deeper understanding of the volatile compounds that influence the odour of dog faeces is important. This study aimed to identify changes of faecal odour compounds that are most prevalent in French Bulldogs based on food containing different high‐quality protein sources and their effect in sensory analysis. Four maintenance foods with different protein sources were formulated: P, poultry meal food; W, wheat gluten food; PW, poultry meal and wheat gluten food; and PWH, poultry meal, wheat gluten, and hydrolysed protein food. Eight adult French Bulldogs were arranged in a 4x4 Latin square design and adapted to foods for 28 days. Fresh faeces were collected for analysis of volatile organic compounds (VOCs) and sensory analysis. The means were compared by SAS, and statistical significance was indicated by p ≤ 0.05. No adverse effects were observed in the animals regarding VOCs, and a significant difference was observed in two of the 68 compounds identified. The animals fed a P food had higher concentrations of phenol in the faeces, whereas the indole compound was present at higher concentrations in animals fed the W food. P food was associated with higher odour perception during sensory evaluation. In summary, the source of protein in the foods had little impact on the composition of VOCs, and a greater perception of the odour was determined by sensory analysis when foods containing animal protein were administered.

A case study of 13-year-old neutered female Lhasa Apso was referred to a veterinary teaching hospital for investigation of dyspnea and episodes of syncope over the preceding 7 days. Topics include referring veterinarian had previously made a diagnosis of stage D myxomatous mitral valve disease; and Physical examination of the dog revealed a respiratory rate of Cardiac auscultation revealed a grade 6!6 holosystolic murmur over the left and right cardiac apex.

Primary hepatic neuroendocrine tumors (PHNETs) are rare in dogs, and limited information exists about the treatment of these tumors. A 12-year-old castrated male French bulldog was presented to our clinic with gastrointestinal signs. Diagnostic tests revealed increased hepatic enzyme levels, a mass in the hepatic quadrate lobe, multiple intrahepatic nodules, and enlarged hepatic hilar lymph nodes. The liver mass was diagnosed cytologically as a malignant epithelial tumor suspected to be of neuroendocrine origin. The dog was treated with single-agent toceranib phosphate (TOC) and survived 25.1 months after the initial presentation. On necropsy, a liver mass was found and was subsequently diagnosed as a PHNET on histopathology. To the best of our knowledge, this is the first report of long-term survival in a dog with PHNET treated with TOC. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to investigate and compare the anatomical features of the nasolacrimal drainage system (NDS) in three brachycephalic dog breeds with those of normocephalic dogs, taking into account how the NDS was related to the malformed brachycephalic head. Animals: Fifty-one brachycephalic dogs were examined, comprising 23 Pugs, 18 French Bulldogs, and 10 English Bulldogs. Six normocephalic dogs of different breeds served as a comparison. Methods: Computed tomographic dacryocystography was performed. Parameters such as length, angulation, and gradient were determined. Crossing of the nasolacrimal duct (NLD) beneath the maxillary canine root, as well as the incidence of an accessory opening, were also analyzed. Results and conclusions: In all three brachycephalic breeds, the NDS was grossly malformed. We regard this as a further consequence of exaggerated breeding for a short head conformation. While the length of the NLD was substantially reduced by 41 to 57 percent in brachycephalic dogs, their lacrimal canaliculi were two to three times as long as those of normocephalic dogs. Varying parts of the nasolacrimal drainage system followed an inverse direction in short-headed dogs, giving the entire nasolacrimal apparatus an anomalous U- or V-shaped appearance. The NLD exhibited a three to five times steeper alignment in brachycephalic dogs than in normocephalic ones. Obviously, this strong slope did not cause clinical symptoms only because there was an aberrant outflow pathway. The brachycephalic dogs consistently exhibited an accessory opening, through which most of fluid escaped into the posterior nasal cavity instead of through the common route into the nasal vestibule via the nasolacrimal ostia.

Objective: To describe the incidence, morphology and clinical significance of congenital vertebral malformations (CVM) in two breeds of brachycephalic dogs presenting to a referral veterinary hospital. Design: Prospective cohort study series. Materials and methods: Forty‐nine French Bulldogs and Pugs were prospectively evaluated and placed in one of two groups based on whether or not they presented for neurological signs referable to spinal cord disease. A computed tomography (CT) of their entire spine was obtained and the presence and classification of CVM along with the degree of spinal kyphosis recorded for all dogs. Statistical analysis was performed to identify clinical associations between these factors (P < 0.05). Results: CVM were prevalent across both breeds with the French Bulldog having more malformations than the Pug (Kruskal–Wallis nonparametric analysis of variance, P < 0.0001). Breed associated vertebral malformation subtypes included butterfly subtype in French Bulldogs (Chi‐square, P = 0.0002), and transitional subtype in Pugs (odds ratio, 22.7; P = 0.000). A new subtype, dorsal wedge, was observed in 12 cases. The presence, number and subtype of vertebral malformation were not reliable for predicting the development of neurological signs across both breeds (Chi‐square, P > 0.05). However, spinal kyphosis >35° calculated via Cobb angle was associated with Pugs that had neurological deficits (Chi‐square, P = 0.028). Conclusions: Congenital vertebral malformations largely appear to be incidental findings in this population of French Bulldogs but are of more significance in the Pug breed when spinal kyphosis is >35°. French Bulldogs that have spinal cord disease and CVM are more likely to have pathology distant to CVM with intervertebral disc herniation most common. [ABSTRACT FROM AUTHOR]

Pectus excavatum is considered a pathology of the chest wall where there is convexity in the ventral aspect of the sternum, which generates secondary complications, such as ventrodorsal stretching of the chest and increased intrathoracic pressure, among others. In the present case, the body of a French bulldog dog was born with previous signs of decay and low consumption of maternal waste, in addition to a forensic medical evaluation. According to the pathological evaluation, a crack was found in the sternal chest related to the caudal sternum close to the xiphoid cartilage, frothy content in the laryngeal epiglottis cartilage and severe signs of emphysema in the caudal, cranial and middle lung lobes. In the cardiological evaluation, an invaginating morphological asymmetry was observed in the interventricular septum in the same area in which the sternal cleft occurs, in turn, in the radiographic evaluation, it shows a dorsal depression of the caudal third of the sternum with considerable changes in the cardiac silhouette. In Colombia there are no reports of complete litters that present this alteration, so it is intended that this is the first anatomopathological and imaging report that describes the pathology in canines.
