Introduction: Lifespan and time of death of dogs died in Switzerland between 2016 and 2020 were evaluated in order to increase the awareness of the public to animal welfare-related consequences of extreme brachycephalic breeding and to clarify the torture breeding problem of dogs suffering from brachycephalic obstructive airway syndrome (BOAS). Skull shape, body size, country of origin and altitude of the registered place of residence at the time of death were analysed in a set of anonymized data from the national animal database Amicus as potential factors influencing the life expectancy. Death rate during summer months and the altitude of the reported place of residence at death were analysed in relation to the skull shape to demonstrate the heat intolerance of brachycephalic dog breeds. The final dataset included 137 469 dogs. The average age of death of the study population was 11,8 years, mixed breeds reaching a higher average age of 12,4 years than purebred dogs with 11,5 years. Bodyweight classification, skull shape and the origin of the dogs had a significant effect on the average lifespan. Giant breeds reached with 9,0 years the lowest mean age compared to the other bodyweight categories. The mean life expectancy of brachycephalic dogs was 9,8 years, i.e., 2,1 and 1,7 years less than mesocephalic and dolichocephalic dogs, respectively. Brachycephalic dogs and dogs imported from abroad showed increased mortality at a young age.

Introduction: In Switzerland, compared to the United Kingdom or the United States of America, fewer veterinary anaesthetists are employed in private practice, which raises the question about the reason. The present survey aimed at investigating the awareness of pet owners concerning the specialization of veterinary anaesthesia and the value they attribute to such a specialist. Also, estimation of pain in dogs and cats and the importance of its treatment from the point of view of the pet owners was analysed. Furthermore, the necessity of veterinary anaesthetists in private practice and the influencing factors were investigated. The survey was created on LimeSurvey, an online tool for questionnaires and sent to dog and cat owners of the small animal clinic of the University Hospital of Zurich. 317 fully completed questionnaires were evaluated. In general, pet owners appreciated the specialization of veterinary anaesthesiology. Great importance was attributed to the supervision of anaesthesia and analgesic therapy by a specialist. A preliminary talk with an anaesthetist would be appreciated. Owners would be willing to cover additional costs for a specialized anaesthetist, if recommended by the private veterinarian, and to bring their animal to the University Hospital, in case of an increased anaesthetic risk.

Introduction: The Entlebucher Mountain Dog is predisposed to ureteral ectopia and associated diseases of the urinary tract as well as the kidneys, which can have severe to lethal consequences. Due to the clustered occurrence of clinical signs in 11 % of Entlebucher Mountain dogs in the absence of a genetic test for ureteral ectopia, screening was introduced in 2008 to allow phenotype-based breeding selection. The ureteral orifices of the dogs are visualized by ultrasound and existing urinary retention or urinary incontinence is documented. The diagnostic findings were evaluated centrally with assignment to one of five phenotypes depending on the localization of the ureteral orifices and the renal and ureteral shape. Breeding approval and mating restrictions are the responsibility of the respective breeding associations and predominantly Entlebucher Mountain Dogs with extravesical ectopic ureters and/or clinical signs were excluded from breeding. The effect of phenotype-based selective mating on the incidence of ureteral ectopia and its clinical signs, as well as possible factors influencing the expression of the phenotype, were determined in the birth cohorts after the introduction of screening. Analysis of the data set of 1456 phenotyped Entlebucher Mountain Dogs showed, that at 11 % versus 5 %, males were more frequently assigned to the extravesical phenotype than females. The effect of phenotype-based breeding selection was examined in a subpopulation consisting of phenotyped parents and their offspring (n = 876). The prevalence of the extravesical phenotype decreased from 24 % in the 2005 to 2007 birth cohorts to 1,4 % in the 2015 to 2017 birth cohorts. Since 2015 almost no Entlebucher Mountain Dogs with incontinence, hydroureter or hydronephrosis have been recorded. It was feared that the additional selection measures to control ureteral ectopia in the small Entlebucher Mountain Dog population would intensify the inbreeding increase. However, this has so far remained absent. Therefore, as long as no genetic test is available, it is recommended to continue phenotype-based breeding selection with exclusion of dogs with extravesical ureteral ectopia and/or hydroureter/hydronephrosis/urinary incontinence, while keeping an eye on the development of the inbreeding coefficient.

Introduction: As part of the national strategy on antibiotic resistance (StAR), a therapy guide for the prudent prescription of antimicrobial agents in animals was developed. To facilitate its implementation in the veterinary practice, the therapy recommendations contained therein have been translated to the user-friendly decision support AntibioticScout.ch. In this context, we conducted a non-representative survey to assess the level of awareness as well as usage of this guide and the AntibioticScout.ch decision support. Based on case studies with typical diseases in dogs, cats and cattle, it was shown that the veterinarians participating in the survey strive to handle antibiotics responsibly and to prescribe them with restraint. Nevertheless, the survey points to possible improvements in the antibiotic therapy. In particular, the StAR guidelines or AntibioticScout.ch can be useful to the practicing veterinarians for taking into account all relevant decision criteria in the optimal selection of a suitable antimicrobial agent.

Killing of animals is an important task to be performed by veterinarians. Killing decisions and their implementation often raise ethical questions. As a result of an interdisciplinary workshop targeting the subject "killing of animals" with veterinarians and ethicists, a three-dimensional dimension scheme was developed. Whereas the first two dimensions are focused on the animal's past and future life and are discussed with regard to life quality and life accomplishment (the "telos"), the third dimension incorporates the reason to kill and may integrate the concept of dignity. This form of dignity and the weighing of interests are applied to example scenarios and the resulting responsibilities of veterinarians and society are discussed.

Professional veterinarians are one of the most affected professions when it comes to killing animals. However, in some situations the opinion about the acceptance of killing of animals differs between people, which can cause a dilemma for the executing person. In a pilot study based on questionnaires, veterinarians from different working fields and students of different branches stated their acceptance of killing of animals in diverse concrete situations. The result clearly demonstrates a higher acceptance of killing of animals among veterinarians with longtime experience in contrast to other groups and the almost same acceptance among agricultural students. The acceptance increased with age, however, we could not find a gender specific difference except of within a narrow age interval. The variability of acceptance within the same profession group differs between the situations. Veterinarians should be aware of their different thinking about killing of animals in some situations compared to other people and should know the reason of such differences. This is important not least to protect themselves and their opinion and to contribute to their societal responsibility by their veterinarian activity.

The behavior of 100 healthy dogs and 100 healthy cats was analysed during their physical examination from "head to tail". A complete physical examination was possible without restraint in 70 % of the dogs and 76 % of the cats. Only a partial examination was possible in 24 % of the dogs and 20 % of the cats. The physical examination could not be correctly performed in 6 % of the dogs and 4 % of the cats. 16 % of the dogs and 13 % of the cats showed aggressive or dangerous behavior. Male dogs were more frequently aggressive than bitches (p = 0.01).
