Understanding Cushing’s Disease in Dogs (Canine Hyperadrenocorticism)
The information we provide in this review is meant to support your veterinarian’s recommendations. If you suspect your furbaby has Cushing’s Disease, consult with his vet. Fido’s doctor knows him best and will be able to guide you through the diagnosis and treatment of this disease.
Is There a Difference Between Cushing’s Disease and Cushing’s Syndrome?
With this condition, the adrenal gland produces excess cortisol, usually due to a tumor either in the adrenal or pituitary gland. This hormone is involved in regulating stress, weight, and blood sugar, and it helps the body to prevent infections.
Signs of Cushing’s Disease
- Polydipsia - your pooch will be thirsty and drink more than usual
- Polyuria - as a result of the increased water intake, your pal will need to pee more frequently and may have more accidents
- Polyphagia - increased appetite
- Pot-belly
- Panting
- hair loss or thinning
- Skin conditions including rashes, thinning, infections, white patches
- Muscle weakness
- Sluggishness
- Bruising
- Enlarged liver/liver disease
- Weight loss
- Sweating and heat intolerance
Diagnosis of Cushing’s Disease
- ACTH stimulation - Your veterinarian can measure levels of blood cortisol before and after an injection of a synthetic version of Adrenocorticotrophic hormone (ACTH). A significant increase of cortisol in Fido’s blood is a confirmation of Cushing’s Disease.
- Low-Dose Dexamethasone Suppression (LDDS) - Your pal’s doctor can measure blood cortisol levels, administer a low dose of the corticosteroid dexamethasone, then check cortisol levels after 8 hours. In dogs without Cushing’s, the levels usually drop, but false-positive results are possible. This test requires an 8-hour stay at the clinic.
- High-Dose Dexamethasone Suppression - This test is similar to LDDS, except the doctor gives your pup a high dose of the corticosteroid.
- Urine Cortisol- Creatinine - This test is a way to rule out Cushing’s, but it will not provide a definitive diagnosis. A high level of cortisol in the urine is one symptom of the disease, but there could be other reasons for the elevation.
- X-ray/Ultrasound - X-rays or ultrasound may demonstrate an enlarged liver or adrenal glands, and it may show calcium deposits in the skin. These are signs that support but do not necessarily confirm a diagnosis of Cushing’s.
Diagnosis of Cushing’s Disease
Conventional Treatments
- If a cancerous adrenal tumor is a cause, it can be removed surgically
- In the case of a pituitary tumor treatment involves radiation therapy because
- Oral medications that work to decrease the amount of cortisol the adrenal gland secretes.
Holistic/Natural Treatments
a holistic approach involving dietary management, supplements, and herbal remedies like Ginko and Si Miao San may help to manage and reduce the symptoms of Cushing’s Disease. You can also use some holistic measures in combination with traditional approaches to support your pal’s overall health.
Vet-Recommended Diet for Canine Cushing’s Disease
- Low in Fat - cortisol leads to higher levels of triglycerides and cholesterol. Look for foods with less than 12% fat on a dry matter basis. To calculate the percent based on dry matter, subtract the moisture content from 100 (for the total dry matter), then divide the percentage of the nutrient by the dry matter.
- Moderate Fiber - Your pooch will need moderate levels of fiber (8-17% on a dry matter basis).
- Highly digestible protein source - Pooches with Cushing’s disease fare better with digestible proteins. They need the amino acid building blocks to help prevent muscle wasting, which is common in dogs with Cushing’s. Good sources of digestible proteins include eggs and muscle meats like beef, chicken, and lamb.
- Low purine levels - Organs like the liver are high in purine, so it’s best to avoid products with organ meats.
- Low Sodium and Chloride - This is particularly important if your furbaby suffers from high blood pressure.
- Low calcium - Low calcium food can help to minimize mineral deposits in the skin.
- Rich in lignans like seeds, whole grains, nuts, fruits, and vegetables.
Can Dietary and Nutritional Therapy Cure Cushing’s?
Dietary and Nutritional Therapy will not cure Cushing’s Disease, but it can go a long way in helping to control the condition. Providing the proper balance of fat, fiber, and digestible proteins help to keep high cortisol levels in check and to support your pal’s immune system. A diet formulated with Cushing’s in mind may improve your pup’s quality and length of life.
Commercial Diets for Dogs With Cushing’s
While many people believe a raw diet can help dogs with Cushing’s Disease, there are quality commercial diets available. When choosing a manufactured product, read the label and compare it to the dietary features we discussed above. Remember to talk to your veterinarian about nutritional recommendations before making any decisions. He knows your pal’s unique dietary needs and can provide meaningful guidance.
The Pros and Cons of a Raw Diet for Dog’s With Cushing’s
- Greater energy levels
- Healthier coat and skin
- Increased muscle strength and reduction of wasting
- Improved digestion
- Stronger bones and teeth
However, there are potential concerns or issues involved with feeding a raw diet. First, the ingredients may not meet all of your pup’s nutritional needs, so that you would need to add supplements to achieve a properly balanced diet. Raw meats also carry the risk of bacteria that can make your pooch sick if his immune response fails to protect him. Finally, you’ll need to follow careful cleaning procedures after each meal to prevent contamination from the raw products.
Supplements for Cushing’s Disease Diets
- Fish oil - fish oil can help with lowering triglyceride and fat levels.
- Digestive enzymes/probiotics to aid healthy digestion and boost immunity.
- If you’re feeding a raw diet, you may need to supplement with calcium and phosphorus for bone health.
- Antioxidants including beta carotene, tocopherols, methionine, vitamin C, and selenium can help regulate fats in the blood.
- There are a variety of herbal and natural supplements that may be helpful. Examples include milk thistle, burdock, Si Miao San, nettle, rosehips, and apple cider vinegar. Consult with your veterinarian or a holistic nutritionist before making any changes to Fido’s diet.
4 Health Care Tips for Dogs With Cushing’s Disease
- Don’t Limit Fido’s Water - Dogs with Cushing’s Disease usually have increased thirst. It’s important to let your pooch drink as much as he wants. You can make his life easier by placing water bowls in the rooms where Fido spends most of his time.
- Give Extra Potty Breaks - Your pal is drinking more, so he’ll need to pee more. Plan on extra potty breaks, and watch your pooch for signs like pacing that indicate he needs to go outside.
- Try More Frequent Feedings - Cushing’ dogs tend to be ravenous all day long. By feeding your furbaby every couple of hours, you can help stabilize blood sugar and provide a more consistent sense of fullness. This can also help prevent your pal from eating anything he can find.
- Exercise Your Pal - As long as your pup is up to it, provide time for exercise. Activity and fresh air can help regulate energy levels, mood, and sleep.
