Does your dog seem more lethargic than usual? Has he started to put on weight despite a lack of appetite? Is he exhibiting changes in behavior that are starting to worry you?
Your dog is your baby and your best friend, so you’re right to worry if you notice changes in his health or behavior. The three changes mentioned here are some of the most common symptoms of a hormonal imbalance disorder called hypothyroidism. This is a condition that affects a small gland in your dog’s neck but can have a big impact on his total health and wellness.
In this article, we’ll explore the subject of hypothyroidism in dogs in greater detail to teach you what you need to know about the symptoms, diagnosis, and treatment of this disease.
We’ll also talk about how to choose the best dog food for dogs with hypothyroidism and show you our top 10 picks.
The Basics About Hypothyroidism in Dogs
The thyroid is a small gland located in your dog’s neck and it is responsible for producing certain hormones that regulate essential bodily functions.
One of the functions the thyroid regulates is metabolism – if the thyroid becomes overactive, it elevates the dog’s metabolism and, if it becomes under active, it slows it down. As you can imagine this leads to corresponding changes in body weight.
The term for an overactive thyroid gland is hyperthyroidism and hypothyroidism refers to an under active thyroid. In dogs, there are two primary causes for hypothyroidism – lymphocytic thyroiditis and idiopathic thyroid gland atrophy.
Unfortunately, hypothyroidism is a tricky condition to diagnose. It isn’t because the symptoms are difficult to identify, however. The real trouble is that the diagnostic criteria for the condition have changed over the years.
If you’re wondering just what hypothyroidism in dogs looks like, here is a quick dog hypothyroidism symptoms checklist:
- Weight gain (often without increase in appetite)
- Lethargy or low energy
- Lack of interest in exercise or play
- Intolerance to cold
- Dry, dull hair with increased shedding
- Thinning hair and/or bald spots
- Increased skin pigmentation
- Frequent ear infections
- High cholesterol levels
- Slow heart rate
In addition to these common symptoms of hypothyroidism in dogs, some breeds experience additional abnormalities such as thickening facial skin, abnormal nerve function, loss of libido, fat deposits in the eyes, and keratoconjunctivitis sicca (KCS) or dry eye.
Many of the symptoms related to hypothyroidism in dogs are physical, typically related to metabolism. In some dogs, however, it can cause behavioral changes. According to veterinarian Dr. W. Jean Dodds, there is a connection between abnormal behavior and thyroid issues in dogs.
Some dogs experience unprovoked aggression, sudden seizures, moodiness, erratic temperament, fearfulness, compulsiveness, irritability, or even anxiety. In fact, when it comes to dog hypothyroidism, anxiety seems to be an increasingly common problem.

The 10 Best Dog Foods for Hypothyroidism
The best dog food for thyroid issues is not necessarily an expensive prescription diet. In fact, veterinary diets made with low-quality ingredients could do your dog more harm than good. Instead, look for a recipe from a reputable brand made with high-quality, natural ingredients.
It should be rich in protein and healthy fats with low-to-moderate levels of digestible carbohydrates. It also doesn’t hurt if it contains beneficial supplements like iodine, chelated minerals, or probiotics.

What Role Does Diet Play in Treatment?
The primary treatment for hypothyroidism in dogs is thyroid replacement therapy (TRT), typically in the form of orally administered drugs. Most dogs with hypothyroidism require TRT for the rest of their lives. The most commonly used oral synthetic thyroid hormone replacement drug for dogs is levothyroxine, known by the brand names Synthroid or Thyro-Tabs Canine.
Though diet does not cause hypothyroidism in dogs, it does play a role in treatment. For the most part, the best diet for dogs with hypothyroidism is one made from wholesome, natural ingredients that is highly digestible and formulated to provide balanced nutrition.
Luckily, most commercial dog foods are formulated to provide for a dog’s basic nutritional requirements, but not all dog foods are created equal. Looking for the AAFCO statement of nutritional adequacy gives you an idea whether a product is intended for use as a staple diet or supplemental feeding, but that statement doesn’t indicate the quality of the product or the ingredients used.
Simply put, the quality of your dog’s diet has a significant impact on his health. Particularly for dogs with metabolic issues, it is important to provide a stable source of calories and balanced nutrition, so your dog’s body doesn’t have to deal with the stress of dietary changes on top of dealing with the symptoms and treatment of hypothyroidism.
What to Look for in a Good Dog Food for Hypothyroidism
When shopping for dog food for thyroid issues, don’t feel like you have to go the route of prescription diets. Though veterinary diets are formulated to address specific dietary or health problems, they are extremely expensive and, in many cases, use low-quality grains and fillers as well as plant-based proteins.
The best diet for any dog is one made with natural, whole-food ingredients that is formulated for the dog’s size and life stage.
Here are some things to look for in a dog food for thyroid issues:
Rich in lean, high-quality animal protein. Protein is the most important nutrient for any dog because it supports muscle mass. Look for lean protein options to help your dog maintain a healthy body weight – things like chicken, turkey, and fish are great options.
Balance of omega-3 and omega-6 fatty acids. Many of the symptoms caused by hypothyroidism in dogs are skin- or coat-related. Omega-3 and omega-6 fatty acids help improve and maintain the health and condition of your dog’s skin and coat, not to mention providing fat-soluble vitamins and a concentrated source of energy.
Low-to-moderate levels of digestible carbohydrates. Dogs have a limited ability to digest plant products, so any carbohydrates in your dog’s diet need to come from highly digestible sources like whole grains and starchy vegetables.
Some veterinarians recommend grain-free diets for dogs with hypothyroidism because many grains used in dog food are GMO. If you choose a grain-inclusive diet, make sure they are non-GMO grains.
Thyroid-supporting nutrients. On top of meeting your dog’s needs for protein and healthy fats, look for a recipe rich in thyroid-supporting nutrients like iodine, iron, vitamin A, vitamin B, and folic acid. Liver, for example, is rich in these nutrients.
No artificial additives or low-quality fillers. For the most part, dog foods made with premium-quality ingredients tend to be free from artificial additives and fillers, but it never hurts to check. When it comes to things like added vitamins and minerals, look for digestible, bioavailable options like chelated minerals.
By now you should have a thorough understanding not only of what hypothyroidism in dogs is, but how to treat it. We aren’t qualified to provide detailed veterinary advice, so make sure to talk to your vet for testing and diagnosis information. If you’re simply looking for healthy dog food for hypothyroidism, however, you’ve come to the right place. Try one of our best ten recommendations above!
Can dog food cause thyroid problems?
Hypothyroidism in dogs is often an autoimmune disease and may be caused by environmental factors. A highly processed or low-quality diet may contribute to poor health in dogs and certain unnatural ingredients may trigger a change in hormones that could affect your dog’s thyroid gland. Generally speaking, however, dog food does not cause hypothyroidism and the right dog food can play a helpful role in treating the disease.
What dog breeds are prone to hypothyroidism?
For many years, it was thought that the dogs most commonly affected by hypothyroidism were middle-aged dogs from mid-to-large-sized breeds. Today, however, it has become clear that the majority of dogs diagnosed with this condition are fairly young adults between the ages of 1 and 2, not 4 to five. There no longer seems to be a connection between breed size and hypothyroidism either, though it is becoming an increasingly common problem in rare breeds. Some of the breeds most commonly affected by hypothyroidism are Akitas, Chow Chows, Doberman Pinschers, Boxers, and Cocker Spaniels as well as popular breeds like Labradors, Golden Retrievers, and Rottweilers.
What are the symptoms of thyroid problems in dogs?
If you’re looking for a dog hypothyroidism symptoms checklist, simply scroll back up! If you’re looking for a more general overview, however, here’s where you’ll find it. Dog hypothyroidism causes the thyroid gland to be less active than it should be which causes problems with your dogs’ metabolism. Changes in metabolism can affect your dog’s body weight and energy levels, and hypothyroidism often correlates with behavioral changes as well. Some of the most common symptoms, however, are related to the dog’s skin and coat – things like dryness, dull hair, excessive shedding, increased pigmentation, and failure to regrow hair after clipping.
What happens if hypothyroidism is left untreated in dogs?
Hypothyroidism is a very treatable condition but, unfortunately, it cannot be cured. Just because it can’t be cured, however, doesn’t mean you should forgo treatment. Untreated hypothyroidism in dogs can lead to serious complications such as dangerous weight loss and a number of secondary diseases such as corneal ulcers, anemia, and adult-onset megaesophagus. Some dogs may also develop other adult-onset problems like seizures, heart problems, and infertility.
