A dog's body is made up of several organs that are working together to ensure good shape and better existence. One of which is the thyroid - a small gland located in the neck area and is responsible for hormone production that regulates a variety of essential bodily functions. 

Just like in humans, the thyroid glands in dogs should also function fully and correctly; otherwise, it can cause more serious health issues such as hypothyroidism.

Dogs suffering from this condition often exhibit symptoms, including dull coat, thinning fur, scaly skin, excessive shedding, reduced physical activities, and weight gain. 

While hypothyroidism is not life-threatening, it still requires lifelong treatment with proper medication and supplements. Moreover, making specific changes in the dog's diet can significantly prevent the condition from worsening.

In this article, we will give you a comprehensive guide on how to choose the best dog food for hypothyroidism.

Dog Food for Hypothyroidism: Buyer's Guide

Dogs suffering from hypothyroidism should be given the best and healthiest nutritional needs. Keep in mind that the healthier the diet, then the quicker and the better they'll be able to restore their optimal functions.

Here are the things to consider in choosing a good hypothyroidism dog food.

1. High-Quality Ingredients

To ensure healthy bodily functions, your dog food should have high-quality ingredients. The shorter the list of ingredients used in its formulation, the better results it can give to your pets.

Also, try to look for wholesome and natural foods such as protein, fats, fruits, and vegetables.

2. Animal Protein

High-quality animal protein from fish, meat, and poultry are the best foundation on your dog's diet. These components are biologically valuable since they contain all the ten essential amino acids entirely for your pet's growth and development.

Lean protein from turkey and chicken are also great options if your dogs gain weight due to hypothyroidism.

3. Grain-Free

best dog food for dog with hypothyroidism

While some dogs can tolerate whole grains, most commercially available dog foods use GMO ingredients, which can have a significant impact on the hormonal balance.

4. Highly-Digestible

Giving your dogs easy to digest foods offer maximum nutritional benefits.

While animal-based diets are the most digestible options, looking for digestion-supporting supplements such as probiotics and prebiotic fibers can also be of great help.

5. No Artificial Additives

The addition of artificial colors, flavors, and preservatives can cause an impact on your dog's thyroid function, thus naturally preserved dog foods should be the primary choice.

6. Fatty Acids

Most of the symptoms caused by hypothyroidism are skin or coat related. The presence of healthy fatty acids such as omega-3 and omega-6 can improve and maintain your dog's skin conditions. 

Also, these fatty acids are good sources of concentrated energy and fat-soluble vitamins.

7. Digestible Carbohydrates

Since dogs have limited ability to digest plant products, the carbohydrates present in your dog's diet should come from highly-digestible sources such as starchy vegetables and whole grains. 

8. Thyroid-supporting Nutrients

Formulations suitable for hypothyroidism should be rich in thyroid-supporting nutrients such as iron, iodine, folic acid, Vitamin A, and Vitamin B.

Other than a change in diet, some of the things that you can do to manage dogs suffering from hypothyroidism were as follows:

What if Hypothyroidism is Left Untreated?

Hypothyroidism is very treatable, but cannot be cured. Just because it can't be cured doesn't mean that you should forgo treatment.

When left untreated, dogs can have severe complications, including rapid weight loss and secondary diseases such as anemia, and corneal ulcers. Some dogs may also suffer from adult-onset problems like heart disease, seizures, and infertility.

Can Hypothyroidism Cause Dog Anxiety?

While the most common symptoms of hypothyroidism are the physical ones, those untreated cases will eventually have behavioral problems such as depression, aggression, fearfulness, and anxiety. 

In dogs, anxiety may be observed with excessive chewing, scratching, digging, or licking. They may also have the feeling of reluctance to leave the house and fearfulness with unfamiliar conditions.

Final Thoughts

Dogs with hypothyroidism are most likely to take medications for the rest of their life to ensure proper management of their condition. While it is not a dietary disease, feeding your dogs with high-quality foods can help support their health and help ease the hypothyroidism.

Among the products we reviewed, Canidae All Life Stages Premium Dry Dog Food is our ultimate choice for the best dog food for hypothyroidism.
