What Is Hypothyroidism in Dogs?

Hypothyroidism is a health condition where a dog’s thyroid gland does not secrete or produce adequate thyroid hormones throughout the body. It is also a hormone imbalance due to inflamed or shrank thyroid glands, leading to insufficient thyroid hormone levels and decreased thyroid function. 

A dog’s thyroid gland is in the mid-neck region near the larynx or the voice box. It consists of two separate lobes located on either side of the trachea or windpipe. Once this thyroid gland encounters abnormalities or diseases, it can affect the dog’s metabolism and other body functions of most organ systems.

Symptoms of Hypothyroidism in Dogs

Since hypothyroidism influences multiple organ systems in a dog’s body, your furry friend will exhibit signs of this disease in different body parts. Primary and common symptoms are

  • Weight gain without an increase in appetite
  • Obesity
  • Dull and dry hair with excessive shedding
  • Increased dark skin pigmentation
  • Slow heart rate
  • Lethargy or lack of physical activity
  • Cold intolerance
  • High blood cholesterol
  • Skin and ear infections
  • Very thin to almost bald hair coat
  • Failure to regrow hair after shaving

In more cases of hypothyroidism, you can also see these signs on your dog:

  • Anemia
  • Thickening of facial skin
  • Reproductive issues
  • Dry eyes
  • Abnormal nerve function

Causes of Hypothyroidism in Dogs

Your furry friend can get hypothyroidism from various causes, such as the following:

Lymphocytic Thyroiditis

This health condition is an autoimmune disease where the dog’s body attacks the thyroid gland or the thyroid tissues. It is an inherited trait that affects thyroid hormone production.

Idiopathic Thyroid Gland Atrophy

Idiopathic thyroid gland atrophy is where fats replace the dog’s thyroid tissues. Unfortunately, the cause of this health condition is still unknown.

Congenital Defects or Abnormalities

Dogs can also acquire hypothyroidism from different defects and abnormalities in the thyroid gland, which they can encounter at birth.

Thyroid Cancer

Thyroid cancer can also cause hypothyroidism, but this condition is rare in dogs.

Other External Factors

Dogs get hypothyroidism from other reasons, such as lawn chemicals, environmental toxins, raw foods, unhealthy commercial dog foods, vaccines, dog chew toys with phthalates chemicals, and antibacterial agents in soap.

Which Dog Breeds Are At Risk of Hypothyroidism?

Research by Ahlgren and Uimari found that a dog breed named Finnish Hovawart has a moderate to high probability of acquiring hypothyroidism through breeding. They concluded that dog breeders must refrain from letting them mate because they can pass the disease to their offspring. One tip is to select affected dogs from unaffected ones to prevent its prevalence.

Aside from this breed, the following are other dogs that are also susceptible to getting this disease.

  • Maltese
  • English Setter
  • Beagle
  • Polish Lowland Sheepdog
  • Dachshund
  • Havanese
  • Dalmatian
  • Miniature Schnauzer
  • Golden Retriever
  • Irish Setter
  • Boxers
  • Cocker Spaniel
  • Doberman Pinscher
  • German Wirehaired Pointer
  • Keeshonds

What To Look For In a Dog Food For Hypothyroidism 

Pet owners must be careful what to feed a dog with hypothyroidism because their furry friend’s health is at stake. Dogs will suffer severe consequences if you let them eat unhealthy meals, so here’s a list of what to look for in dog foods to help them live through hypothyroidism. 

Animal-Based Protein

Canines require animal-based protein and nutrient sources, such as poultry, meat, and fish, for easy digestion and to support lean muscle mass. Opting for animal-based fats like salmon oil and chicken fat will also give them the energy to combat lethargy. Moreover, essential fatty acids will aid your dog’s skin or coat issues. 

Low Fat

Even though excessive unhealthy fats are dangerous for dogs, you can find healthy fats, such as flaxseed, canola oils, and omega-3 fatty acid, to aid hypothyroidism. Research by Chiofalo et al. stated that a diet rich in protein and fats can benefit thyroid glands and thyroid hormone production in dogs.

Highly Digestible Nutrients

Unexplained weight gain is a common effect of hypothyroidism in dogs, so weight management is crucial to handle this situation. You can give foods that are easy to digest for more nutritional value. In this case, animal-based protein, probiotics, and prebiotic fibers are excellent ingredients for maximizing vitamins and minerals. 


Even though your dog can tolerate whole grains, commercial dog foods have GMO (genetically modified organisms) ingredients that influence the hormonal balance in dogs. It can be risky to pick dog foods without checking if their grain contents are GMO-free, so grain-free diet plans are better for saving time and your dog’s safety.

Balanced Nutrients

You will want to give your dog everything to boost its health, but balancing the nutrients and minerals should also be considered. You can serve carbohydrates and fibers for healthy digestion, iodine for thyroid hormones, vitamins A and B, folic acid, and iron for enhanced blood health and thyroid function.

High-Quality Ingredients

Dogs with hypothyroidism can lose their appetite, so you must give them the healthiest ingredients of the highest quality to maximize their nutritional value. You can choose wholesome and natural foods, animal proteins, fats, vegetables, and fruits. Do not forget to check your dog’s allergies to prevent allergic reactions to specific foods.

No Artificial Flavors and Preservatives

Commercial dog foods can also have artificial colors, flavors, or preservatives that can affect your dog’s thyroid function and other organ systems. In this case, carefully select foods and ingredients with 100% natural preserves, such as rosemary extract, vitamin E, dried egg whites, ascorbic or citric acid, and mixed tocopherols. 


A research on microbiota and thyroid interaction by Frohlich and Wahl states that microbiota-targeted therapies can benefit thyroid diseases. Microbes in probiotics regulate iodine degradation and uptake and enterohepatic cycling. With this, you can start letting your dog eat plain yogurts with no artificial sweeteners and kefir with live cultures.
