A dog’s thyroid gland is located in their neck and has two lobes, one on each side of the trachea. The thyroid is responsible for regulating the body’s metabolism. Dogs with an overactive thyroid experience hyperthyroidism, and their metabolic rate increases. Dogs with an underactive thyroid experience hypothyroidism, and the metabolic rate decreases. Dogs with hypothyroidism are prone to weight gain even without overeating, dull coats with hair loss, and lethargy.

While medication is usually prescribed to help treat hypothyroidism, diet also plays an important role in managing your dog’s quality of life. The right food can give your dog the energy that they need and improve the look of their skin and coat. Natural foods with wholesome ingredients are ideal.

Buyer’s Guide

If you suspect that your dog may have hypothyroidism, it’s important to make an appointment with their vet right away. Food will not cure thyroid issues, and you should always consult your vet before making any changes to your dog’s diet. Different conditions can have signs that mimic each other, and the only way to accurately diagnose hypothyroidism is with a blood test. Once you know what condition, if any, your dog has, you can start managing it.

What Is Hypothyroidism?

The thyroid is a tiny organ in the neck that secretes the hormone thyroxin, which helps the body regulate its metabolism, among other things. When the thyroid does not produce enough thyroxin, there will be an insufficient amount of it in your dog’s body for normal functioning. This is known as hypothyroidism.

Signs of Hypothyroidism Include:

Which Breeds Are the Most at Risk for Hypothyroidism?

Any dog can be affected by hypothyroidism. However, some breeds seem to be more prone to this condition than others:

What to Look for in Food for Dogs With Hypothyroidism

Animal Protein

Dogs need animal-based protein in their diet. Fish, poultry, and beef provide essential amino acids that your dog requires to be healthy. Lean protein sources from poultry are ideal for dogs with hypothyroidism because they are less likely to promote weight gain. Protein is the easiest ingredient for your dog to digest, so the higher the protein content in the food, the easier it will be on your dog’s digestive system.

Healthy Fat

The healthy fat in your dog’s food helps boost their energy levels, though the protein content should always be higher than the fat content of the food. Healthy sources of fat are omega fatty acids. These are usually found in fish. Flaxseed and canola oils are also commonly used as healthy fats. Pork and poultry fat can be found in many dog foods, along with vegetable and sunflower oils.

Avoid anything with lard in it. Lard is an example of an unhealthy fat.

Easy Digestibility

Animal-based protein from only one or two sources and the addition of probiotics and prebiotics are good signs of how easy a food will be for your dog to digest. The easier the digestion is, the more nutritionally complete the food is for your dog. Since weight management is something to consider, you want the food that you feed your dog to be as nutrient-dense as possible.

Good Flavor

All dogs want to eat foods that taste good to them, but dogs with hypothyroidism may need a little encouragement to eat. Dogs may not always have an appetite and may need to be coaxed to eat the food that they need even if it tastes good. While many dog owners may believe that their dogs will “eat it if they get hungry,” this is not a good rule to follow when it comes to dogs with health issues. They need proper nutrition and should be fed high-quality, nutritious food that they enjoy eating, even if takes trial and error to find the right one.

Ingredients to Avoid

Artificial colors, flavors, and preservatives should not be fed to dogs with hypothyroidism. Fillers provide poor nutritional value, and some dogs can have trouble digesting them. Foods heavy in grains and gluten can be difficult on a dog’s digestive system.

Will My Dog Be Cured?

There is no cure for hypothyroidism, but the condition can be managed for the rest of your dog’s life. The most common treatment is synthetic hormone replacement. Medication will be given to your dog every day that will control their hormone levels and get them back to feeling like themselves.

Always consult your vet before changing your dog’s diet. If you suspect that your dog may have a health issue, getting a proper diagnosis and knowing the ways to treat the possible condition are the only ways to ensure that you can keep your dog as healthy and happy as possible.
