Archive Case #94: Canine Hyperadrenocorticism

Clinical Clues

1. An older dog is presented for increased drinking, frequent urination, and constant panting.
2. The owner says the appetite has become excessive over the past several months.
3. On examination the abdomen is pendulous and muscle mass is reduced over the limbs.
4. The coat is thin and the skin bruises easily.
5. Bloodwork shows a marked increase in alkaline phosphatase activity.
6. Chronic excess cortisol production commonly causes this constellation of metabolic and skin changes in dogs.

Diagnosis

Canine Hyperadrenocorticism

This case is most consistent with Canine Hyperadrenocorticism because the dog has PU PD, polyphagia, panting, a pot-bellied appearance, and typical skin changes. The most important clues are the chronic course and elevated alkaline phosphatase, which make a simple urinary disorder less likely.
