A 9-month-old French Bulldog with pulmonary stenosis (PS) underwent transthoracic echocardiography (TTE) and electrocardiogram-gated coronary computed tomography angiography (ECG-CCTA) for presurgical planning of pulmonary balloon valvuloplasty (PBV). Transthoracic echocardiography revealed severe PS and identified two distinct coronary ostia (left and right). Electrocardiogram-gated coronary computed tomography angiography showed a circumpulmonary course of the interventricular paraconal coronary artery, which abnormally originated from the right coronary artery. Based on this case report, the echocardiographic identification of two coronary ostia does not rule out a coronary artery anomaly with circumpulmonary course (as previously hypothesized), and coronary computed tomography angiography may be recommended for presurgical planning of PBV in French Bulldogs.

CASE REPORT: A 7-month-old male Rottweiler puppy was admitted because of stunted growth. Clinical and clinicopathological examination revealed proportionate growth retardation, lack of primary hairs, bilateral cryptorchidism and mild azotaemia. Plasma growth hormone concentration was low prior to and following stimulation with xylazine, indicating hyposomatotropism. The serum concentrations of insulin-like growth factor-1, prolactin, thyroid-stimulating hormone and total and free thyroxin were low. Plasma luteinising hormone concentration was low prior to and following stimulation with gonadotropin-releasing hormone. Adrenocorticotropic hormone (ACTH) stimulation test and endogenous ACTH concentration were normal. Magnetic resonance imaging of the brain revealed the presence of an intrasellar cyst and a multilobed cystic lesion in the left posterior hemisphere. CONCLUSION: To the authors' knowledge, this is the first report of congenital pituitary dwarfism in the Rottweiler breed that occurred with a pituitary hormone deficiency pattern similar to that seen in German Shepherd Dogs.
