Why Hypothyroidism Happens in Dogs

Like humans, a dog’s thyroid gland plays a vital role in regulating essential bodily functions like digestive function, heart rate, and metabolism by releasing a hormone known as thyroxine. However, once the gland stops producing enough of this hormone, hypothyroidism happens.

This condition is actually quite common among dogs than other household animals. Fortunately, it’s not life-threatening, though it will require treatment using synthetic hormones such as levothyroxine.

Apart from medication, dogs with hypothyroidism can benefit greatly from a high-quality diet which consists of wholesome, natural, and filler-free ingredients.

How to Pick the Right Dog Food for Hypothyroidism

When choosing the right food to give your dog, here are some factors you have to consider:

High-Quality Ingredients

First and foremost, a dog food which is designed for hypothyroidism should contain quality ingredients to help maintain your dog’s healthy bodily function. As much as possible, look for brands that contain natural ingredients like animal proteins, fresh fruits, and vegetables.

Animal Protein Content

As mentioned, you should consider dog foods that contain animal protein. This is because this specific protein will provide your dog with the support he needs to achieve healthy body weight. Also, since animal proteins are considered whole complete proteins, they can give your dog all ten essential amino acids he needs.

Easily Digestible

A digestible food will allow your dog to enjoy its maximum nutritional benefit. Those with animal-based ingredients tend to be the best option for this, though you should also consider looking for supplements like probiotics and prebiotic fibers.


While there are dogs who can tolerate whole grains, most products that contain grain can actually impact the hormonal balance of your pet. Therefore, you want to go for a grain-free formulation as much as possible.

Free of Artificial Additives

lastly, make sure that the dog food you give your dog is free of any artificial additives including flavors, colors, and preservatives. Artificial ingredients will only affect your pet’s thyroid function – which is why you must avoid them at all costs.

Once you’ve picked the best dog food that will suit your dog’s needs, make sure you transition him slowly. Don’t put him into a sudden diet switch at once. Make sure that your dog will get used to his new diet little by little.

You can start by mixing around 30% of his new food with 70% of his old food for a few days. Once he takes a liking to his new meal, gradually increase the percentage until he can fully tolerate the changes.


How much food should I give my dog?

The amount of food you should give your dog will depend on his weight, age, and activity level. Usually, adult dogs will need to eat two meals a day. However, small breeds and those who engage in a lot of physical activities will need three meals. Just keep in mind that your dog’s calorie needs will decrease as he ages.

What ingredients should I avoid?

You want to avoid dog foods that contain by-products. However, not all of them can be bad. Specifically, you want to avoid beef by-products as hypothyroidism in dogs is often linked to cattle consumption containing cow glands and gullets.

Why does my dog’s stool smell?

If your dog’s stool has a very strong odor after taking a dog food that’s designed to deal with hypothyroidism, you shouldn’t worry that much. After all, this is just one of the very few side effects your pooch will experience, and it’s due to the absence of additives in the food.
