Choosing Dog Food For Your Dog’s Hypothyroidism

If your dog has hypothyroidism, there are some things that you need to keep in mind. This includes the type of food they need. Here’s what you need to know.

Hypothyroidism in Dogs

The thyroid gland is one of the essential glands that your dog has. It’s controlled by the pituitary gland and aids in regulating their metabolic rate.

Your dog’s metabolism slows down when the thyroid gland is underactive, thus hypothyroidism. 

This can cause many symptoms, including; 

  • Weight gain, even though there is no increase in appetite
  • Extreme lethargy 
  • Cold intolerance
  • Dry and dull hair 
  • Excessive shedding
  • Increased dark pigmentation in the skin
  • Slow heart rate
  • Lameness or dragging of the feet
  • Lack of coordination
  • Infertility in female dogs
  • Fat deposits in eye corneas

Hypothyroidism is treatable but not curable. When your dog needs medication, it’s treated with thyroid hormones. This requires lifelong treatment. 

Of course, a proper diet can also help. But, you’ll want to watch out for key ingredients, which we share below. 

Dog Breeds and Hypothyroidism

While any dog can have hypothyroidism, some breeds are prone to have it. It usually affects mid and large-size species and is rare in smaller dogs. 

The most common breeds with hypothyroidism are: 

This is not to say that every dog in these breeds will have hypothyroidism. But if you have these breeds and your dog is exhibiting any of the symptoms, please see your vet immediately. 

What to Look for in Dog Food for Hypothyroidism 

There are a few key components to look for when it comes to your dog’s diet with hypothyroidism. 

Animal Protein

Hypothyroidism can cause extreme weight gain and obesity. To build lean muscles, and give your dog plenty of nutrition — choose animal based ingredients and protein. 

This includes real meats and meat meals, like chicken, fish, lamb, beef, turkey, and even venison. 

Animal-Based Fat

One of the most common symptoms of hypothyroidism is dry and dull skin. Your dog may also have an excessive shedding coat. Animal-based fats like chicken fat, beef fat, salmon oil, and fish oil can make a huge difference. 

First, they’re needed to provide energy. And they can promote healthy skin and stop itching, scratching, and hair loss. The omega fatty acids can also reduce inflammation and boost cognitive function.


Last but not least, it’s crucial to choose a digestible formula for your dog. Focus on recipes that have higher bioavailability of fats and protein. In other words, you want a formula that your dog that can get quality nutrients from. 

How do you do that? Choose formulas that focus on novel proteins (like fish or lamb — if needed). Plus, focus on options that don’t have too many fillers. Limited ingredient dog foods, grain-free options, and high-protein formulas are excellent options. 

Also, quality fiber is important, to aid in digestion and boost the thyroid hormone. 

Ingredients You Should Avoid

Luckily, many dogs with hypothyroidism don’t need too specialized of a diet. But, there are a few ingredients that you should avoid when possible. 

Fillers like wheat, beef by-products, and artificial additives are best to avoid. They can cause problems with your dog’s thyroid since they aren’t easy to break down. 

Medication can help the absorption of nutrients. But these ingredients aren’t worth the extra work your dog’s body will have to do to absorb them.

Our Verdict

Hypothyroidism can cause some exhausting symptoms. But it doesn’t have to affect your dog’s day-to-day life. With the right treatment plan and high-quality food, your pup can live a long and fulfilling life. 

Our favorite is Earthborn Holistic Primitive Natural Grain-Free Natural Dry Dog Food

It’s full of omega fatty acids to reduce inflammation and protect joints. It also has vitamin C for immune health. These are all significant benefits for dogs with hypothyroidism. 

But the other foods on this list are great and can support your dog. What’s most important is choosing a formula that works for your dog’s needs.


Have questions about your dog’s hypothyroidism? Here are a couple of asked questions and our answers.

Can dog food cause thyroid problems?

No, because most dogs get hypothyroidism as an inherited disease. But, iodine deficiencies or too much iodine in the diet can exacerbate symptoms. And foods with fillers or a lack of nutrients can also worsen symptoms. 

What happens if hypothyroidism goes untreated in dogs?

If your dog has hypothyroidism and it’s left untreated, they are at risk for more severe health issues. This includes diabetes, anemia, vision loss, lameness, and even death. 

While your dog may not need medication, they need a diagnosis for hypothyroidism. Be sure to talk to your veterinarian about the best way to support your dog with this disease.
