Do you have a pet with Hypothyroidism? Then here are the 10 Best Dog Food for Hypothyroidism that you should definitely consider!
Having a pet can be a huge responsibility, and one of the biggest concerns as a canine parent is keeping your pet healthy and happy. Unfortunately, much like us, dogs can develop thyroid problems. However, with proper medication, nutritious meals, and ample physical activity, you can ensure that your dog remains healthy despite these issues.
Dealing with hypothyroidism can be tricky, especially when it comes to picking food that will work best to maintain your dog’s health and fitness. But, if you know what you are looking for and what you need to stay away from, you can make your decision easily and confidently.
There are innumerable dog food varieties available in the market, and while it is usually easy to simply pick any one of these appealing options, choosing one that will be suitable for a dog with hypothyroidism can be especially daunting.
Your dog’s health is always the top priority, so we have come up with a list of dog foods that are best suited for dogs with hypothyroidism.
Hyperthyroidism vs Hypothyroidism

Before you go out and make a purchase, you should familiarize yourself with the illness itself. The thyroid gland is located in the throat and is responsible for the release of the hormone that makes sure that the body is using the energy effectively.
The hormone secreted by the thyroid gland affects the functioning of the brain, heart, muscles, and organs. The malfunctioning of the thyroid gland can result in one of the two kinds of thyroid ailments- Hyperthyroidism and Hypothyroidism. The hormone output by the thyroid gland is the primary difference between the two.
In the case of Hypothyroidism in dogs, the pituitary gland produces inadequate amounts of TSH (Thyroid Stimulating Hormone), resulting in inadequate production of thyroid hormones and under activity of the thyroid gland. As a result, the functioning of the thyroid gland slows down and negatively impacts the dog’s bodily functions and metabolism. If for some reason, your dog is unable to produce an adequate amount of thyroxine, it results in hypothyroidism.
The symptoms of hypothyroidism in dogs are weight gain, decreased levels of activity, mood changes, swelling, fatigue, and dry fur and skin.
Hyperthyroidism, on the other hand, results from the over-production of the TSH hormone from the pituitary gland as well as an increased rate of metabolic activity. Thyroxine, which is released by the thyroid gland directly, affects your dog’s metabolism and health. If for some reason your dog is unable to release enough of these particular thyroid hormones, it results in Hyperthyroidism.
Due to hyperthyroidism, your dog might experience diarrhoea, overheating, anxiety, and fatigue, as well as problems with sleep and loss of weight. Obesity, thinning and falling hair and flaky or thick skin are also symptoms that you should check for. In some cases, Hyperthyroidism can also result in the growth of a tumour.
Both hyperthyroidism and hypothyroidism are serious illnesses, but are different from one another and exhibit different symptoms. It is always a good idea to get your dog tested if you suspect it might be suffering from thyroid problems, rather than diagnosing them yourself since incorrect diagnosis and treatment can further aggravate these health issues and worsen the conditions.
What to Look For When Choosing Dog Food?

Usually, simply picking a brand or variety that seems healthy can be good enough.
However, when shopping for a dog with hypothyroidism, uninformed decisions are not enough.
You must know what you are looking for which ingredients you want and which ones you don’t want so that your dog can enjoy the best possible quality and care.
Here are some things you should look for when shopping for food.
Protein Content
While considering food options for your dog, you must pay special attention to the protein content they offer. Premium animal proteins are essential for canines suffering from hyperthyroidism, as they help maintain healthy body weight and lean muscle mass.
Due to hypothyroidism, your dog is more likely to easily gain weight, which can negatively impact its health. So, you should consider including animal protein in your dog’s diet, to curb the accumulation of fat in the body.
Iodine Content
Iodine promotes the production of thyroid hormones and reduces the symptoms of hypothyroidism. Iodine, however, is often not present in dog food. You can easily purchase dog-friendly iodine to add to your canine’s food bowl.
Fruits and Vegetables
Fruits and vegetables are good sources of nutrition for your dog and provide the appropriate vitamins and minerals required for consistent and good health. The consumption of fruits and vegetables provides for a healthy and active dog.
Quality
The quality of the food you give to your dog will impact their health heavily. It is important to make sure you are providing them with the best quality food consisting of natural and wholesome ingredients. Your dog’s food must also be easy to digest since the rate of metabolism is affected negatively by hypothyroidism.
Grain-Free
If the dog food you use has high grain content, it can lead to unhealthy weight gain, which is extremely harmful to a dog suffering from hypothyroidism. Corn, wheat, and soy are often used as fillers in dog food and should be avoided. These fillers are sometimes produced with GMOs (Genetically Modified Organisms) and are not beneficial in any way. Some dogs are also allergic to these grains, so it is a good idea to check the ingredients before you purchase any dog food.
Animal Liver
Animal liver is rich in folic acid, Vitamin A, Vitamin B, and iron. It improves the functioning of the thyroid gland. While purchasing dog food, you should try to choose one that contains animal liver.
Animal Based Fats
Side effects of hypothyroidism such as dry skin can be improved with help of certain animal fats. These fats are a good source of omega fatty acids and can be found in food items such as chicken fat and salmon oil.
Supplements
Thyroid problems in dogs can be improved with the consumption of glandular supplements. You can add these supplements to your dog’s foods and mix them in since they are rarely added to dog foods as an ingredient.
Breed
Some options available in the market cater specifically to the needs of a particular breed. While considering what to buy, you should keep an eye out for such breed-specific varieties.
What to Avoid When Selecting the Best Dog Food for Dogs With Hypothyroidism?
Just like you need to look for beneficial ingredients, you also need to make sure you are not giving your dog anything which could cause potential harm. There are certain ingredients that can deteriorate your dog’s health and strength, so you should know what these are in order to avoid them.
Gluten
Your dog’s unstable thyroid levels will cause trouble with digestion, and a diet full of grains will only aggravate these issues. So, you should look for a dog food that is free of grains that have high gluten content.
Beef Byproducts
Consumption of beef byproducts is also a cause of hypothermia in dogs. They worsen the dog’s health, and so it is a good idea to avoid them as much as possible.
Fillers
Fillers are those ingredients in dog food that do not provide any nutrition and serve no purpose. They hinder the efficient absorption of nutrients into the body and should be avoided too.
Artificial Additives
Artificial preservatives, colors, flavors, and ingredients should not be a part of your dog’s diet. They can impact the thyroid gland and cause further harm. So, you should check to make sure that the food you are giving to your dog consists of natural ingredients only.

FAQ
We know it can be daunting to deal with health issues when it comes to your furry best friend. The illness can be scary, but if you know what it entails, you can do your best to keep your dog healthy and safe. We have answered some of the most basic and frequently asked questions about hypothyroidism so that you can maintain your peace of mind and know that you are providing your dog with appropriate care and treatment.
Can Dogs Have Thyroid Related Issues?
Yes, it is possible for dogs to develop thyroid problems, though it is most common in old and middle-aged dogs.
What Are the Symptoms of Hypothyroidism?
While it is important to be perceptive when it comes to your pup’s health, you should avoid self-diagnosing him or her. It is always a good idea to visit a vet if you have any suspicions so that you can take appropriate actions and follow instructions given by a professional.
Easily identifiable symptoms of hypothyroidism include changes in the dog’s fur and coat and their visibly poor conditions. Inexplicable weight gain and laziness, dull and weak mental state and inability to deal with physical activities, and low temperatures are some of the symptoms. Other, more severe symptoms might be extreme hair loss, loss of muscles, slow heart rate, toenail and ear infections, and seizures in extreme cases.
Can Hypothyroidism Cause Seizures?
Seizures occur due to an imbalance of thyroid hormones. Fewer amounts of thyroxin in the body make your dog more prone to seizures. However, hypothyroidism is not the only cause of seizures, and it is possible that there is something else that is causing them.
Can the Dog Eat Before a Thyroid Test?
To ensure accurate test results, you should make sure that your dog does not eat anything for at least four hours before the blood is taken for the test. If your dog is already taking thyroid medication, you should wait for four hours after administering the medication, but make sure not to wait more than six hours after the medicine has been taken. This means that you have a window of two hours to get the test done.
Can Hypothyroidism Cause Death?
While hypothyroidism itself does not usually cause death in dogs, it can significantly worsen their overall health conditions. Hypothyroidism can also make other illnesses more serious, and it can also make the dog more prone to various other diseases since it weakens the immune system. If left untreated, it can cause adult-onset megaesophagus, which can result in death.
Thyroid carcinoma, which is a form of cancer-related to the thyroid, can also be a remote possibility. However, you must keep in mind that it is possible for you to keep your dog’s health in check. As long as you get them tested and treated, and take action after educating yourself thoroughly about the condition and what it entails, you will not face any serious issues. You want what’s best for your dog and its health, and if you do your best to provide for its specific needs you will be alright.
