How to Choose the Best Dog Food for Your Dog’s Cushing’s Disease
Once your dog gets diagnosed with Cushing’s disease, you may be wondering about their dietary changes. Here’s what you need to know.
Cushing’s Disease in Dogs
Cushing’s disease is an incurable but treatable condition. A tumor usually causes it in the pituitary gland. It requires consistent monitoring because the adrenal gland produces excess cortisol. Also, it can be tricky to diagnose.
Cushing’s disease causes common symptoms like extra stress, weight gain, spiked blood sugar, and lowered immunity. Some other dog’s cushing’s symptoms include;
- Frequent urination, especially at night
- Extreme thirst
- Muscle loss and weakness during advanced stages
- Thinning of the skin
- Lesions on skin
- Hair loss
- Lack of energy
- High cortisol levels
If your dog is experiencing any of these symptoms, take them to your vet immediately. Usually, your dog will undergo many tests to diagnose Cushing’s disease. It’s expensive and difficult to diagnose.
A few of the tests involved include blood tests and urine tests. But they will also check your dog’s liver, and an adrenocorticotropic hormone (ACTH) stimulation test. In some cases, an ultrasound can also determine whether your dog has a tumor.
Once they diagnose your dog, treatment will vary based on the location and size of the tumor (if they have one). While tumors are usually easy to remove in people, it’s harder to do with dogs.
So instead, your vet may recommend medication to limit the growth of the tumor or keep it from releasing too much cortisol.
Along with this treatment plan, you’ll most likely need to switch your dog’s food. This is to ensure that they’re getting supplements that aid in their recovery.
Can Dietary Therapy Cure Cushing’s?
Nothing can cure Cushing’s disease. It’s a treatable disorder, but it is lifelong.
But the proper diet and nutritional therapy can work well with your dog’s medications or treatments. And it can limit symptoms and help them live a fulfilled life.
Commercial Diet for Dogs with Cushing’s Disease
Even if your pup has Cushing’s disease doesn’t always mean that they need a special or vet recommended diet. You can feed your dog commercial dog food unless otherwise noted by your vet. We’ve included our top 10 options above.
Raw Diet For Dogs with Cushing’s Disease
Would you prefer to feed your dog a raw or homemade diet? While most vets recommend against these diets (unless you’re working with a canine nutritionist or vet), it’s possible. Just keep in mind that it can be more work for you as their owner.
A raw diet can increase their energy levels, give them healthy skin, and increase lean muscle mass. These are all great things for dogs with Cushing’s disease.
But it’s essential to make sure the raw food is safe. Since raw meat can contain harmful bacteria that affect gut and immune health, this can exacerbate dogs’ symptoms with Cushing’s.
Choosing dehydrated or freeze-dried raw food is a better option.
If you choose a homemade diet, be sure to work with your vet. This is to ensure your dog is getting all the vitamins and minerals they need, along with protein, fat, and carbohydrates.
What to Look for When Buying Food for Cushing’s Disease
Now that you know more about Cushing’s disease and how to support your pup with the proper diet better let’s talk about what to look for in their dog food.
Highly Digestible Protein
Your dog’s metabolism and digestion system won’t have to work as hard to process the food with highly digestible protein.
And these proteins also include essential amino acids to build and maintain lean muscle, which is harder to do with Cushing’s.
Look for digestible protein sources like real meats — including chicken, lamb, fish, beef, and eggs. Meat meals are okay too but should be the first ingredient.
If your dog also suffers from allergies, a hydrolyzed protein formula may work well.
Low in Fat
With Cushing’s disease, cortisol levels are higher, which can cause other issues like blood sugar spikes and higher cholesterol. Because of this, a food that’s lower in fat can help manage these issues.
While upwards of 15% Crude Fat is okay, the lower, the better. Foods with fat levels between 10%-12% are best.
All dogs need fiber, but it’s vital for dogs with Cushing’s disease. Fiber helps regulate gut health, keeps stool firm and regular, and also helps keep the digestive tract clear.
Look for ingredients like prebiotics (found in many complex carbs) and starches like potato starch.
With Cushing’s disease, your dog’s kidneys and liver can also be affected. To keep these organs in better shape, look at foods lower in purines.
This means avoiding formulas that have a lot of organ meats and limited portions of mussels and sardines.
Low Sodium and Chloride
While this isn’t a concern for all dogs with Cushing’s, it is essential to consider if your dog also experiences high blood pressure. You may also want to stick to low sodium if your dog is a senior since their metabolism and heart won’t be as strong as during their young years.
All dogs need calcium. But, pups with Cushing’s disease shouldn’t have too much. This is because excess calcium can cause mineral deposits in the skin to become painful.
Instead, choose a food that doesn’t have more than 2% calcium.
Your furry friend can still live a long, healthy, and fulfilled life with canine Cushing’s disease. With the right treatment plan and the proper diet, they’ll be back to their usual self in no time at all.
Our favorite is Purina Pro Plan Adult Weight Management Formula dry dog food.
This dog food contains plenty of prebiotics and probiotics to better digestion and reduce inflammation caused by Cushing’s.
But no matter which dog food you choose, this list has foods that support dogs no matter their age, breed, or how much TLC they need.
