Canine Infectious Diseases Q12.PNG


A 6-year-old neutered male, 20.6 kg mixed breed dog (see image) was referred for a cardiac work-up, because the referring veterinarian had heard a new continuous heart murmur. The dog was known to have had a systolic murmur for several years. Along with dental prophylaxis, a grade I mast cell tumour had been surgically removed from the right thoracic limb 1 year previously. There was no history of exercise intolerance or other clinical signs. The dog lived in Ingolstadt, Germany, and was current on vaccinations and treated regularly with parasiticides. He had never travelled outside Germany. Physical examination revealed that the dog was active, alert, and responsive. The rectal temperature was 38.9°C (102.0°F), mucosal membranes were moist and pink, capillary refill time was <2 seconds, all lymph nodes were of normal size, and abdominal palpation was unremarkable. Lung sounds were physiologic, and the respiratory rate was 36 breaths/min. A left basal continuous heart murmur with an intensity of V/VI was audible. The regular heart rate was 128 bpm. Pulse quality was normal, without pulse deficit or evidence of jugular vein distension/pulsation. The remainder of the physical examination was unremarkable.
