Best Dog Food for Hypothyroidism: 5 Complete, Enriched Diets! (2024)

Best Dog Food for Hypothyroidism

It’s estimated that over 4.6 % of the American population suffers from hypothyroidism to some extent.

However, underactive thyroid function is also a common health condition in our canine friends.

Hypothyroidism is a condition where the thyroid gland produces insufficient thyroid hormones. Dogs most commonly develop hypothyroidism between the ages of four and 10.

The most prevalent symptom of this disease in both humans and dogs is unexplained weight gain, but dogs may also experience symptoms such as skin conditions and fur loss.

Left untreated, the symptoms of hypothyroidism will worsen with serious potential consequences for your dog’s quality of life.

Although hypothyroidism can’t be cured, it can easily be treated through a combination of diet and medication.

A dog suffering from hypothyroidism requires a diet consisting of high levels of antioxidants, probiotics, and amino acids, including plenty of lean, high-quality protein.

Bearing this in mind, we’ve put together a list of the 5 best dog foods for hypothyroidism.

These are some of our favorites!

We’ve also created a buyer’s guide and an FAQ section to support you in making the best dietary decisions for your poorly pooch.

We understand that you’re probably anxious to provide your fur baby with the best hypothyroid diet as soon as possible. To save time, take a look at our top choice:

Buyer’s Guide


As we mentioned earlier, dogs with hypothyroidism have specific dietary requirements.

All dogs need high-quality protein in their diets, but those suffering from hypothyroidism are even more dependent on it for maintaining lean muscle and keeping up energy levels.

Additionally, a canine diet for hypothyroidism should contain plenty of amino acids, antioxidants, probiotics, and iodine.

These are the nutrients we have prioritized in our selection of foods.

The proteins included in our reviewed range of foods are, where possible, sourced from real meat for optimal and natural nutrition.

We’ve also selected foods that provide healthy but not excessive amounts of carbohydrates from different sources.

Dogs are omnivorous, and while there is no specified daily amount of recommended carbohydrates for dogs, canines can benefit from a certain amount of plant-based carbs.

Be sure to check with our Ultimate Guide to Dog Food for help in understanding label terminology and potentially harmful ingredients.

Dogs with hypothyroidism may experience lethargy, so they benefit especially from moderate carbohydrate levels for energy.

Brown rice and wheat, for example, are excellent sources of this nutrient. For dogs who are sensitive to grains, sweet potato is another good option.

Other beneficial ingredients included in some of the foods we reviewed are glucosamine and chondroitin. These two nutrients are vital for joint health and functionality.

Because one of the main symptoms of hypothyroidism in dogs is weight gain, joint pain and weakness may arise as a side effect.

By supplying adequate amounts of chondroitin and glucosamine in your dog’s diet, you’ll be helping to keep their joints healthy and strong, maintaining their mobility in the face of potential weight gain.

We also feel it’s important to note that many of the foods advertised as suitable for canine hypothyroid sufferers are grain-free or wheat-free formulations.

Due to the increasing awareness of grain and gluten intolerance in humans, many owners instinctively believe that grain-free dog food will be the healthiest option for this dog.

However, most of the time, this is not the case.

While grain or wheat-free dog foods are certainly the preferable options for dogs with sensitivities, allergies, or intolerances to these ingredients, the prevalence of these conditions in dogs is not as high as many might think (around 10%), and most dogs are able to process wheat and grains perfectly well.

In fact, recent studies have indicated that a grain-free diet may increase the risk of dilated cardiomyopathy in dogs.

Therefore, we advise opting for one of the grain-free formulas on our list only if your dog has a known sensitivity to this food group.


While perusing our reviewed products, you may have noticed that all of the options featured on our list are dry dog foods as opposed to wet or canned varieties. There is a reason for this.

There are, of course, many benefits to wet food varieties for dogs, including increased hydration and a lower calorie density.

However, most vets advise against feeding dogs an all-canned diet, and since consistency is key to ensuring your dog regularly gets all the specific nutrients needed to combat hypothyroidism, an all- kibble diet is likely to be the best option.

Dry dog food also has the added benefit of being less expensive, so it’s more affordable for the long-term, which is desirable given that hypothyroidism is a treatable but not curable condition.

However, there may be cases where canned dog food will be the better option – for example, if your dog also suffers from conditions such as renal failure, which requires extra hydration.

Ideally, you should consult your vet before making any food purchases since they will be able to advise you professionally with your dog’s specific health status in mind.


In order for your dog to benefit fully from hypothyroid-specific nutrition, it’s important that they enjoy the food enough to eat sufficient quantities of it.

That’s why it’s so helpful that so many of the dog food brands we’ve reviewed offer multiple flavor options.

Whether your dog prefers chicken, lamb, beef, or salmon, there’s a dog food on our list to match.

It’s also worth considering the fact that, since most of the brands reviewed in this article use real meat to source their proteins and flavorings, some flavors are likely to have their own individual benefits.

For example, salmon is an excellent source of fatty acids – particularly omega-3.

Fatty acids are essential in supporting thyroid function, so this is an example of how specific dog food flavors can actually benefit thyroid health.


We briefly discussed the benefits of dry dog food varieties earlier, but one advantage we didn’t mention is that dry food is generally much easier to store and tends to come in a wider range of quantity options.

Depending on the size of your dog, the severity of their hypothyroidism, and the presence of any other pre-existing health conditions, your vet is likely to recommend a specific diet.

No two dogs are exactly the same, so your companion might require more or less food on a daily basis than someone else’s.

Therefore, you’ll probably need to think about how much food your dog needs and how much you want to have stocked up in advance.

Many of the brands reviewed above provide multiple bag size options, so you can purchase their dog foods in quantities that meet your dog’s needs, either as needed or in bulk.

Frequently Asked Questions

How Do I Know If My Dog Has Hypothyroidism?

The only way to conclusively diagnose hypothyroidism in dogs is through thyroid hormone testing, which measures T4 concentrations in the blood.

However, there are many warning signs and symptoms that can help you to catch the condition early.

The two main symptoms of hypothyroidism in dogs, much like in humans, are lethargy and unexplained weight gain.

Your dog might sleep more than usual, move more slowly, or lose interest in exercise.

You may also notice that your dog is gaining weight despite there having been no change in diet or appetite.

Other symptoms of hypothyroidism in dogs include increased sensitivity to cold, skin irritation, and hair loss.

As hair begins to thin, you might also notice a darker pigmentation in your dog’s skin.

If you notice any of these symptoms, the best thing to do is not to panic and contact your vet as soon as possible.

These symptoms can be indicative of a number of conditions, and hypothyroidism is a very treatable illness.

What Dog Breeds Are Prone to Hypothyroidism?

All dogs can potentially develop hypothyroidism with age, but certain breeds are more prone to the condition than others.

Hypothyroidism is more common in medium and large dog breeds.

Commonly affected breeds include Doberman, Labradors (learn more about Lab predispositions to diseases here), Boxers, and English or Irish setters.

Some smaller breeds also commonly affected by hypothyroidism include Dachshunds and Miniature Schnauzers.

If you know that your dog is predisposed to hypothyroidism, you’ll be in a more informed position to look out for the warning signs and better prepared to offer care should the need arise.
