Cushing's disease, also known as hypercortisolism, occurs when a dog’s adrenal glands produce too much cortisol. The stress hormone cortisol plays a role in fight-or-flight responses and other short-term bodily reactions, but chronically elevated cortisol levels in the blood can negatively affect many aspects of health.

Disrupted Insulin Response

Cushing's disease in dogs can contribute to insulin resistance and is even one of the main causes of insulin-related problems in dogs with diabetes. Dogs with both diabetes and Cushing’s disease tend to have elevated blood sugar levels after meals. The types and amounts of carbohydrates and starches in a dog’s diet influence these blood sugar levels and, consequently, the symptoms of diabetes. These dogs often require increased amounts of insulin and experience significant fluctuations in blood sugar levels after eating.

Feeding a Low-Sugar and Low-Grain Diet

Since excessive sugars, carbohydrates, and starches can cause issues with blood sugar levels in dogs with Cushing’s disease, it may be wise to switch your dog to a diet low in carbohydrates and starches. Ready-made diets specifically designed for dogs with diabetes are available. Frozen or freeze-dried kibble that is rich in omega-3 and omega-6 fatty acids can also be a good option. Additionally, a diet with more raw ingredients, such as the BARF diet, might be suitable for your dog. However, preparing your dog’s meals yourself requires significant knowledge and time as a pet owner. It’s always a good idea to consult your veterinarian before making changes to your dog’s diet.

Salmon Oil as a Supplement for Cushing’s

Supplements can also support the health of a dog with Cushing’s disease. Omega-3 fatty acids may help lower cortisol levels. Moreover, these “healthy fats” have a positive effect on the coat and skin. Omega-3 fatty acids are abundantly found in wild salmon oil. Salmon oil is therefore an excellent supplement to support a dog with Cushing’s disease. It can also boost your dog’s immune system. Additionally, salmon oil naturally contains an antioxidant called astaxanthin. Antioxidants help neutralize free radicals in the body and can support overall health. Astaxanthin also gives salmon oil its characteristic reddish-brown color.

Probiotics

Gut health is also important for dogs with Cushing’s disease. Probiotics can help support digestion. With the help of probiotics, your dog can better absorb nutrients from their food. Probiotics contain “good bacteria,” such as certain strains of the Lactobacillus family. There are special probiotics for dogs available on the market.
