Question 1

A 7-year-old Labrador Retriever presents with polyuria, polydipsia, and bilateral cataracts. Fasting blood glucose is 420 mg/dL. Which insulin type is most commonly used for initial management of canine diabetes mellitus?

Accepted Answer

NPH insulin

Answer

NPH insulin is the first-line choice for canine diabetes mellitus due to its intermediate duration matching the dog's twice-daily feeding schedule.

Question 2

A 5-year-old intact male Cocker Spaniel presents with acute vomiting, fever, and a painful cranial abdomen. Serum lipase is markedly elevated. Which dietary fat level is most appropriate during recovery?

Accepted Answer

Low fat (<10% DM)

Answer

Dogs recovering from pancreatitis should receive a low-fat diet (<10% DM) to minimize pancreatic stimulation and reduce recurrence risk.

Question 3

A 9-year-old Golden Retriever is diagnosed with protein-losing nephropathy. UPC ratio is 4.8. Which antihypertensive class is considered first-line therapy to reduce proteinuria?

Accepted Answer

ACE inhibitors

Answer

ACE inhibitors (e.g., enalapril, benazepril) reduce glomerular capillary pressure and proteinuria and are first-line therapy for PLN.

Question 4

A 4-year-old Boxer presents with episodic syncope. ECG reveals a wide, bizarre QRS complex occurring at a rate of 180 bpm with no preceding P waves. What is the most likely diagnosis?

Accepted Answer

Ventricular tachycardia

Answer

Wide bizarre QRS complexes with no preceding P waves at a rapid rate are characteristic of ventricular tachycardia, common in Boxers with ARVC.
