Cushing’s disease in dogs, also called canine hyperadrenocorticism, is caused by excess cortisol production from pituitary or adrenal tumors. Cortisol affects metabolism, immunity, and organ function, meaning diet plays a critical role in management. According to the Merck Veterinary Manual, dogs with Cushing’s often develop obesity, diabetes, hypertension, skin issues, and infections, all of which can be influenced by nutrition.
What to Feed a Dog With Cushing’s Disease?
Dogs with Cushing’s disease should be fed a low-fat, moderate-protein diet with complex carbohydrates, antioxidants, and omega-3 fatty acids to control complications and improve quality of life.
Vet-recommended food groups:
- Lean proteins: Skinless chicken, turkey, white fish — preserve muscle without adding excess fat.
- Complex carbs: Brown rice, oats, barley — support stable blood sugar and weight control.
- High-fiber vegetables: Green beans, broccoli, zucchini — aid digestion and satiety.
- Omega-3 fatty acids: Fish oil, flaxseed — reduce inflammation and support skin and coat health.
- Antioxidant-rich foods: Blueberries, spinach, carrots — reduce oxidative stress from cortisol damage.
The VCA Animal Hospitals explains that therapeutic diets designed for endocrine disorders can reduce risks of pancreatitis and diabetes while supporting long-term management.
Is Pumpkin Good for Dogs With Cushing’s Disease?
Yes. Cooked, plain pumpkin is beneficial for dogs with Cushing’s disease because it is low in calories, high in fiber, and nutrient-rich.
- Digestive health: Pumpkin helps regulate constipation or diarrhea, which may occur with cortisol imbalance.
- Fiber support: Promotes satiety and healthy gut microbiota.
- Nutrient profile: Contains beta-carotene, vitamin A, and antioxidants.
The American Kennel Club (AKC) confirms pumpkin is safe for dogs when fed without sugar, salt, or spices.
Is Sweet Potato Good for Dogs With Cushing’s Disease?
Yes. Sweet potatoes are safe and beneficial for dogs with Cushing’s disease in moderate amounts due to their complex carbohydrates, fiber, and antioxidants.
- Blood sugar support: Sweet potatoes provide slow-release energy, helping to stabilize glucose levels in dogs prone to diabetes.
- Antioxidants: Rich in beta-carotene and vitamin C, which combat oxidative stress.
- Fiber content: Supports digestion and weight management.
The AKC states that cooked, plain sweet potatoes are safe and beneficial, though portion control is important due to calorie content.
Which Foods Should Dogs Avoid?
Dogs with Cushing’s should avoid high-fat, high-sugar, and processed foods that worsen metabolic disease.
- Fatty meats & fried foods: Increase risk of pancreatitis and hyperlipidemia.
- Refined carbs & sugary treats: Cause blood sugar spikes and worsen diabetes.
- Seasoned human foods: Garlic, onions, and salty foods are toxic or harmful.
- Unbalanced raw diets: May pose infection risks for immunocompromised dogs.
The Cornell University College of Veterinary Medicine advises that nutrition should be individualized by a veterinarian, as complications such as diabetes, obesity, and hypertension are common in advanced cases.
Key Takeaways
- Vet-recommended diet for Cushing’s dogs: Low fat, moderate protein, complex carbs, omega-3s, antioxidants.
- Pumpkin: Safe, fiber-rich, helps digestion.
- Sweet potatoes: Safe, nutrient-dense, support glucose stability.
- Avoid: Fatty, sugary, and processed foods.
- Diet should always be tailored under veterinary supervision alongside medical therapy (e.g., trilostane or mitotane).
