Canine Cushing's disease, also referred to as hyperadrenocorticism, is a disorder most common in older dogs. Its cause can be related to diabetes, though diabetes is not a require precursor. It can result from the administration of steroids, such as prednisone. In these cases, lessening the steroid can significantly help relieve the symptoms. When it is naturally occurring, your veterinarian may have a variety of suggested treatment courses, including drug therapy, surgery and dietary changes. While a complete cure is less likely, the disease can be successfully managed for years, greatly improving the quality of life for the dog.

Symptoms of Canine Cushing's Disease
-
The most common symptom seen in dogs with Cushing's disease is a marked increase in water consumption, called polydipsia. Often dogs with this disorder will up their water intake anywhere from two to ten times the usual amount. This increase can lead to excessive urination and possible development of wetting accidents in the home. A sagging or bloated belly and thinning of coat is also often reported. If you see these symptoms, consult with your veterinarian.
Prescription Diets
-
Medications to normalize adrenal function can be helpful in the treatment of Cushing's. In addition, consider modifying the dog's diet. Speak with your veterinarian about prescription food options. Diets such as Hill's i/d, which supports digestive health, can be a good choice. Be sure to transition to a new food slowly to avoid digestive distress. On day one, mix your dog's usual food with the new food, in a ratio of three parts original diet to one part new diet. After a few meals of this mixture, up the split to 50/50, and finally wean off the former diet with a few meals of three parts new food, one part former food.
Good Diet Choices
-
A recommended diet for dogs with Cushing's disease is outlined in Small Animal Clinical Nutrition III by Morris, et. al. This report suggests focusing on a balanced diet that is rich in protein and low in fiber, fat and purine. Avoid purine-rich foods such as liver, sardines, beef kidneys, mackerel, herring and scallops. If you are not using a prescription diet, check the ingredient list of your dog food for these items. If you feed a raw food diet, or are using a traditional kibble, look for ingredients such as meat, fowl, spinach, lentils, asparagus, mushrooms and peas. Avoid excessive calcium supplements, as this can contribute to calcification. Do not restrict water intake.
