Best Dog Food For Cushing’s Disease

Notice any changes in your pooch lately? Thinning hair or a potbelly perhaps? Has she been drinking too much water or eating just about anything?

These signs could mean that she has Cushing’s disease, or in more technical terms, canine hyperadrenocorticism. Also known as Cushing’s syndrome, this illness is caused by the overproduction of a hormone called cortisol by the adrenal glands – two pea-sized glands situated on top of the kidneys.

Cortisol serves the body well. But too much of this hormone is bad for the immune system, and weakens its ability to fight other diseases.

In this article, you’ll have a better idea about this illness in dogs and how to better manage it. Also, nutritional therapy is known to help in achieving adrenal balance and bring back cortisol production to normal levels. This means feeding your dog with the right diet to better manage Cushing’s disease.

Check out our latest review of the best dog food for Cushing’s disease. As a bonus, we have also included a dry matter analysis of the food’s fat and fiber content to save you from doing the math.

What To Look For In The Best Dog Food For Cushing’s Disease  

A dog’s diet is always crucial to improving overall health and managing health issues. This is why as a dog owner, it’s highly important to know your dog’s nutritional needs well, especially if she has health conditions that need to be managed or addressed.

In the case of Cushing’s disease, a healthy dog’s food can help control the high level of cortisol, help support a healthy immune system, and help prolong the dog’s life.

Most vets will recommend nutritional therapy for dogs with Cushing’s disease. It’s an important step that pet owners must take to help alleviate Cushing’s disease and improve the dog’s condition. Failure to do so could put the dog’s life at serious risk.

Also, muscle wasting is typically associated with Cushing’s syndrome, and nutritional therapy with the right diet can help lighten muscle atrophy. 

It’s important too to keep your pups away from table scraps and cheap treats with high fat and sugar contents. Some vets may also recommend a prescription diet intended for Cushing's syndrome. Although more expensive, a prescription diet is more focused on addressing the health issue.

Here’s what a canine Cushing’s disease diet must look like:

Adult Dog Food Formulas

If you’re feeding your dogs with commercial pet food, pick dog foods that are meant for adult dogs to help ease Cushing’s disease, since adult food formulations (those that meet the standards of the AAFCO) have the nutritional requirements intended for older dogs, which are prone to Cushing’s disease. 

If you give dog foods that are suited for all life stages in dogs, these may have higher fat and caloric contents that may hinder the improvement of your dog’s condition.  

Low in Fat, Low to Moderate Fiber

The abnormal high level of cortisol in the dog’s body also raises triglycerides and cholesterol levels. And so, dog foods with high fat and caloric loads can only lead to a rapid increase in the dog’s weight.

It's best to feed your dog natural low-fat and moderate fiber diets. The ideal fat content is less than 12% on a dry matter basis (DM), and about 5-15% for fiber. 

For commercial dog food, you can compute the DM value by deducting the moisture percentage (as shown in the Guaranteed Analysis on the label of the product) from 100%.

Then, divide the Fat % (indicated also in the Guaranteed Analysis) by the DM value to arrive at the DM Fat value. Use the same formula to compute the DM Fiber value.

Can Dogs Eat Salmon

Highly Digestible Protein

To counter muscle wasting as a result of Cushing’s disease, it helps to have sufficient protein in the dog’s food. A crude protein load of at least 18% for commercial dry dog food and 10% for canned food is recommended.

But it also helps if the protein content is highly digestible in order to aid healthy digestion and for the quick absorption of amino acids and nutrients. 

Among the highly digestible protein in dog food are lean meats and organ meats from chicken, beef, and lamb, and egg whites.

Low in Sodium and Chloride

If your pup is hypertensive, avoid dog food with high chloride and sodium content. A low-sodium and low-chloride dog’s diet can help maintain a normal blood pressure.

Complete and Balanced Diet

Regardless of your dog’s health issues, she needs a diet that offers all the essential nutrients to keep her healthy and protected from other potential illnesses.

Balanced nutrition is when all the essential amino acids, vitamins, and minerals are present in the dog’s food, along with essential antioxidants and omega fatty acids. This is imperative if you want your furry pal to be in perfect health and avoid costly veterinary visits.

High-Quality Ingredients

Natural ingredients from trusted sources are considered as high-quality, which must be a priority when deciding on a dog food. If you’re serving commercial dog food, whether dry food or canned food, always check the ingredient list.

The best commercial dog food options are made with high-quality animal protein and natural whole foods. Preferably, choose the best dog food with a named animal meat (e.g. chicken meat, beef meat) as the first ingredient. 

Other good protein sources are processed meats called meals from a named animal (e.g. chicken meal, menhaden fish meal). Avoid unnamed animal sources (e.g. animal by-products, meat meal), which are mostly poor-quality. 

Free of Artificial Additives and Food Allergens

Choose commercial dog food that’s free of artificial flavors and additives as these could aggravate the dog's health disorders. Check your pup for allergies to some dog food ingredients.

If you have a food-sensitive pooch, pick dog foods with novel protein (e.g. salmon, turkey) as first ingredient, and perhaps a grain-free, gluten-free, and limited ingredients diet. Grain-free foods are free of common allergens like corn, wheat, and soy.

Is Raw Food Diet Better For Cushing’s Disease?

Raw food diet for dogs is becoming more and more popular today as many pet owners associate it with the natural feeding in the wild that dog ancestors relied on.

This comes with the idea that feeding on raw meat is beneficial to the dog’s health and helps prevent a number of common canine health issues, including Cushing’s syndrome.

It’s true that many of the common health problems in dogs are caused by poor diets that we have been feeding our four-legged best friends for many years.

Most of the processed commercial pet foods, especially the cheaper ones, are made with very poor quality ingredients and lack the complete nutrition dogs need to stay healthy. 

A raw diet, at least, doesn’t have any of the harmful artificial components that are found in many commercial pet foods. But raw dog food also lacks some of the essential nutrients dogs need to thrive. You'll need to add supplements.

Feeding raw does have its health benefits including leaner muscle mass, which is great for dogs with Cushing’s disease. It also promotes elevated energy levels, improved digestive health, stronger bones, and better skin and coat. It's also generally safer for sensitive dogs because it's free of additives.

Raw Dog Food Reminders

First, the meat may be contaminated with harmful bacteria such as Salmonella, E. coli, and Yersinia. Another challenge with a raw diet is the preparation aspect.

If you have the extra time to prepare the raw dog meal – cutting, washing, proportioning, blending with other natural ingredients – then that’s fine. Of course, you also need to clean and sanitize the food bowls after the raw foods are consumed, or it would attract bacteria.

Suggestions for Feeding Raw for Cushing’s Disease

For a dogs' Cushing’s disease, the main advantage of feeding raw meals is the high protein content, which should help largely in mitigating muscle wasting – a known symptom of the illness.

If you’re determined to introduce a raw diet, here are some important suggestions:

  • Gradually introduce the new diet by mixing with the old dog food, then gradually increasing the raw portion for about 2-3 weeks. A sudden shift to raw foods will likely result in an upset stomach.
  • Make sure the meat is a high-quality meat and free of harmful bacteria.
  • Mix the meat with raw fruits and veggies for a more balanced diet. Add some eggs too.
  • Provide your dogs with dietary supplements to provide the other nutrients not found in meat. Some dairy products like yogurt with probiotics or supplements with probiotics are also vital for digestive health and better digestion of raw ingredients.

You can try balancing raw diet with homemade dog food, which may be cooked or slightly processed, and high-quality commercial foods in both dry food and wet dog food. You may add small amounts of raw meats.

Home-cooked meals using fresh ingredients are just as beneficial and less problematic. Just make sure to use dog-friendly ingredients like coconut oil or olive oil instead of processed cooking oil. 

Avoid adding unhealthy spices like MSG, or too much salt. Homemade dog food mixed with the best commercial dog food options, including canned food, is great dog food.

Remember that most premium commercial dog foods – AAFCO certified and made with natural ingredients – are enriched with all the essential nutrients needed by dogs to thrive.

If you settle for commercial pet foods, please refer to the guidelines in this article about what to look for in the best dog food for Cushing’s disease. Dry dog foods are more economical and you will find some good options in this review.

Although more expensive, canned dog food has its advantages too like being more nutrient-dense per serving and also more palatable. You can also mix canned food with dry food.

Can Supplements Help Treat or Prevent Cushing’s Disease?

Supplements can help but there's no substitute to a healthy dog food. With a nutritionally-balanced food, supplements may not be necessary. Consult your local vet before buying any supplement to avoid interference with medication.

  • To aid nutritional therapy, supplements with essential antioxidants including beta-carotene, alpha-tocopherol, vitamin C, selenium, and methionine can help in lowering circulating blood fats in the dog’s body.
  • A high-protein food supplement can also help against muscle atrophy.
  • Fish oil supplementation can also help in lowering circulating blood fats and triglycerides, apart from supporting healthy skin and coat and preventing hair loss, which is a symptom of Cushing’s disease.
  • Melatonin is also believed to help manage Cushing’s disease as it regulates hormones and provides antioxidants.

Herbal Supplements

Some homeopathic vets also recommend certain herbs to reduce cortisol levels and help alleviate the effects of Cushing’s disease in dogs.

What Is Cushing’s Disease?

Cushing’s disease, which is named after Harvey W. Cushing, who in 1932 discovered 12 human patients with a serious metabolic disorder stemming from tumors in the pituitary gland, affects humans and animals alike, including dogs and cats.

Cushing's disease is no laughing matter. It's caused by the overproduction of a chemical called cortisol (also cortisone), by the adrenal glands. 

Cortisol helps respond to stress, fight infections, manage body weight, and control blood sugar levels. It is a very helpful chemical to the dog’s body. But too much or too little of it brings significant health complications to dogs, as it does to humans.

In the case of Cushing’s syndrome, the excess cortisol can result in many potential severe health issues such as hypertension, kidney damage, blood clots, and diabetes, which can put the dog’s life at risk.

Cushing’s disease is more common among older dogs, usually starting at seven years old. While it can affect any dog breed, some dog breeds are found to be more commonly affected by Cushing’s syndrome.

Among these dog breeds are small breed dogs like the Boston Terrier, Yorkshire Terrier, Dachshunds, Beagles, and Poodles, and larger breeds like the German Shepherd, Labrador Retriever, and Boxers.  

Causes Of Cushing’s Disease

Cushing’s disease can be classified into three different types, each with a different origin. It’s critical for the vet to determine the type of Cushing’s disease because each type also has a different prognosis and treatment.

Pituitary Gland Tumor

This is the most common cause of Cushing’s disease, which could account to about 85% of cases in dogs. The pituitary gland is located at the base of the brain.

A tumor in the pituitary gland could be benign or malignant, and small or large, that induces the overproduction of a hormone called ACTH, which then stimulates the adrenal glands to produce cortisol. 

Adrenal Gland Tumor

The adrenal gland itself may have a benign or malignant tumor called adenoma and carcinoma respectively that triggers the overproduction of cortisol. If the tumor is benign, surgical removal can permanently cure the condition. If it’s malignant, the condition may recur even after surgery.

Iatrogenic Cushing’s Disease

This is caused by the excessive use of steroids in dogs, typically from oral or injectable medication. Some health disorders in dogs require the use of steroids. However, the prolonged use of steroids can also provoke the overproduction of cortisol.

Symptoms Of Canine Cushing’s Disease

Middle-aged and older dogs are more susceptible to this disorder and the early signs are not easy to detect. Dogs with Cushing’s disease could show one or a few of the following symptoms:

  • Increased appetite
  • Increased thirst, frequent drinking
  • Frequent peeing
  • Weakening of the muscles, atrophy
  • Thinning of the skin 
  • Hair loss
  • Potbelly development, bloated abdomen
  • Panting
  • Lethargy, drop in energy level

Any of these symptoms call for an immediate visit with the animal doctor. 

Diagnosis And Treatment Of A Dog’s Cushing’s Disease

Cushing’s syndrome in dogs can be quite challenging to diagnose even for experienced veterinarians because its symptoms are identical with other health issues like gallbladder disease, gastrointestinal disease, and tumors in the liver.

Various medical tests, like urine and blood tests, may be conducted to pinpoint the main source of your pup’s symptoms and also to eliminate other possible causes. MRI, ultrasound, and adrenal function tests may also be administered if necessary.

Pituitary Gland Tumor

The vet may prescribe medication to lower the dog’s cortisol levels. Although surgery is the more effective way of removing the cause, which is the tumor, medication is the more practical and safer method of treatment. The surgical removal of a pituitary gland tumor is complex and delicate, especially for older dogs, not to mention very costly. 

The most commonly-used drugs are trilostane (Vetoryl) and mitotane (Lysodren). Trilostane disrupts the production of cortisol by the adrenal glands. Mitotane, on the other hand, is a human chemotherapy drug prescribed, “off-label” by some vets for dogs with Cushing’s disease. But this needs careful monitoring by an expert as it can induce serious side-effects.

Adrenal Gland Tumor

For adrenal gland tumor, surgery is the logical treatment. If the tumor is not cancerous, the dog has a great chance of being in the pink of health soon after a successful surgery. 

Iatrogenic Cushing's Disease

For the Iatrogenic Cushing’s disease, the discontinuation of the steroid is required. However, it’s very likely that the disorder being treated by the steroid will recur.

In this case, the vet will recommend other medication or treatment to fix the issue without steroids. This will also likely necessitate the regular monitoring of the cortisol production by the vet as well as regular blood tests.

Treating dogs with Cushing’s disease can be tricky and sometimes frustrating because of constant trial and error but pet parents can do a lot to help by being diligent in bringing the animal to the vet regularly for checkups and for the necessary medical tests and by strictly following the vet’s instructions on medication and other treatment procedures at home.

Pet parents must also constantly watch out for side-effects or other health issues. This way, the vet will have an easier time treating the dog and help prolong its life. Sadly, many dogs are not given enough time by their owners that they continue to suffer and eventually die.

Tips To Help Alleviate A Dog’s Cushing’s Disease

Unlimited Drinking Water

As increased thirst and excessive drinking are symptoms of Cushing’s disease, it’s necessary to always have clean water available for your pup to drink. Do not limit their access to clean water. As in humans, drinking water is healthy. Your pooch will just pee the excess water in her body.

Weight Loss

The vet may also recommend weight reduction measures for your Fido. This you must do to prevent obesity, which poses other health hazards including hypertension and heart disease. Exercise will also do your dogs a lot of good. Take the time to walk them daily. As for a healthy weight diet, you need to consult a vet.

Frequent Feeding in Small Amounts

You can also implement frequent feeding in smaller amounts, which should be easier to digest, and prevent overeating or eating just about anything. This can aid in maintaining a healthy weight.
