Like us, dogs tend to have a slower metabolism as they age. But in some cases, there’s more to it. Pups can also develop hypothyroidism as they get older. If your pal is hitting the middle years of life and you notice a drop in activity, thinning hair coat, and weight gain even though you’re not feeding any more food, they may have hypothyroidism.

Understanding Hypothyroidism In Dogs
Before we dive into information about hypothyroidism, a word of caution. If you suspect that your furry friend has an insufficient thyroid, it’s important that you consult with your veterinarian before making any dietary changes. Other conditions can show similar symptoms, and Fido’s doctor can help you determine if and when you should switch dog foods.
What is Hypothyroidism?
Dogs have thyroid glands in their neck just like we do. These tiny organs secrete the hormone thyroxin, which helps the body regulate metabolism, digestion, heart rate, and other vital functions. As some pups age, their thyroid glands don’t produce enough of the hormone. We call the condition hypothyroidism.
Causes
A furbaby’s thyroid glands can slow down or stop producing thyroxine for several reasons.
- Lymphocytic Thyroiditis is an autoimmune disease where the body attacks the thyroid tissue as if it were a foreign invader. This is an inherited trait, but scientists are not sure what triggers the response.
- Idiopathic Thyroid Gland Atrophy is a condition where the gland shrinks and is replaced with fatty tissue. The cause is unknown.
- Thyroid cancer can cause hypothyroidism, but this disease is fortunately rare in canines.
- Congenital defects or abnormalities with the gland that Fido had from birth is another cause of hypothyroidism.
Symptoms
The symptoms of hypothyroidism appear because of insufficient hormones. Thyroxine stimulates the metabolism, some of the signs you’ll see in a hypothyroid pup are related to a sluggish metabolic rate.
- Weight gain without an increased appetite
- Lethargy and exercise intolerance
- Dull, dry hair
- Excessive shedding
- Hair loss on body
- Cold intolerance
- Fertility problems in intact dogs
- Mental dullness
- Thickened or scaling skin
- Increased skin pigmentation
- Increased likeliness to develop skin or ear infections
Diagnosis
Routine screening: Routine blood panels and complete blood counts may or may not help to diagnose hypothyroidism. There may be an increase in white blood cells if the hypothyroidism is due to an immune response. Some dogs also develop mild anemia. You can see elevated cholesterol levels in about 75% of hypothyroid pups. These results may point to the condition, but further testing is required to confirm a diagnosis.
Thyroid-specific Tests: Usually, diagnostic testing for hypothyroidism involves measuring three hormone levels in the blood:
- Total Thyroxine (T4): Total T4 is a measure of all thyroxine in the bloodstream. Thyroxine can be present in a bound form that’s attached to blood proteins or in a free state in the serum. A normal level means your pup is not hypothyroid. If the value falls below or is in the low normal range, further testing is needed.
- TFree T4: Free T4 measures the amount of unbound thyroxine in the bloodstream. If this is normal, Fido’s in the clear. A value below the normal range in combination with clinical signs is a strong indicator of hypothyroidism. This test is more costly than total T4 and takes longer to get results.
- TEndogenous thyrotropin (TSH): TSH or thyroid-stimulating hormone is secreted by the pituitary gland and is part of a feedback loop. In hypothyroid canines, there may be an increased level of TSH as the body attempts to stimulate the thyroid to put out more T4. This hormone level should be measured in combination with Total T4 or Free T4. As with Free T4, TSH measurements must be done at a referral laboratory.
Treatment
Hypothyroidism is treated with oral hormone replacement therapy with a form of thyroxine. Once Fido develops the disease, he’ll need medication and T4 level monitoring for the rest of his life. There’s no way to cure the disorder.
natural Treatment For Hypothyroidism in Dogs
You will need to provide medication as part of Fido’s hypothyroid treatment. But, there’s more you can do as part of a holistic approach to your canine pal’s health and well-being.
Thyroid Supplementation: Your furbaby will need thyroid hormone replacement to make up for the low levels of thyroxine. For many pooches, this is a lifelong treatment. Talk to your veterinarian about the best hormone brands.
Iodine Supplementation: Iodine is a necessary part of proper thyroid function. However, getting too much in the diet can be as bad as not having enough. Commercial dog foods provide the needed levels of iodine. If you make homemade food for your four-footed friend, talk with your veterinarian about appropriate levels of iodine.
Other Helpful Supplements: As we noted above, there are other supplements that can support your pup’s quality of life. Include omega 3 fatty acids, probiotics, and milk thistle. You may also want to provide thyroid glandular supplements.
What’s the Difference Between Hypothyroidism and Hyperthyroidism?
When the thyroid gland doesn’t secrete enough thyroxine, its called hypothyroidism. Dogs with an inactive thyroid can experience weight gain, lethargy, hair loss, and other symptoms. With hyperthyroidism, the organ is overactive and makes excess levels of the hormone. In the case of hyperthyroidism, your pooch would have an increased metabolism, weight loss, and other symptoms. Hyperthyroidism is rare in dogs and usually a result of cancer.
Which Dogs Are Most At Risk For Hypothyroidism?
- Golden retriever
- Doberman pinscher
- Irish setter
- Cocker spaniel
- Miniature schnauzer
- Dachshund
- Airedale terrier
How Does Diet Affect Hypothyroidism?
Although Hypothyroidism is incurable, you can take supportive measures to help your pal. Good nutrition in combination with hormone replacement gives your pal the tools he needs to manage his condition. Carbohydrates, selenium, zinc, and iodine are important for proper thyroid function. Offer Fido a quality diet of wholesome foods that offers a balance of animal protein, healthy fats, fruits, and vegetables.
Dr. W. Jean Dodds, a holistic veterinarian from Hemopet in Southern California also recommends supplementing your pal’s diet with vitamin E, Ester-C, echinacea, and garlic.
If you use commercial dog food, look for a brand that uses natural preservatives.

9 Tips To Choose the Best Dog Food For Hypothyroidism
When you’re looking for food to feed a dog with hypothyroidism, look for these qualities:
High-Quality Ingredients: Good nutrition and quality ingredients can provide valuable support for a pooch with hypothyroidism. Look for products that have natural ingredients and whole foods like fruits, vegetables, and proteins from animal sources.
Animal Protein Content: As carnivores, dogs need animal-based proteins like fish, meat, and poultry. These sources provide the essential amino acids that Fido needs. Lean proteins such as chicken and turkey are good choices if your pup has been gaining weight because of hypothyroidism.
Grain-Free: Many grain sources for commercial dog foods come from GMO sources. Unfortunately, these ingredients can influence Fido’s hormone balance. Some pups do fine with whole grains, but why gamble. If you can’t confirm that the grains are GMO-free, it’s better to find a food that’s grain-free.
Highly Digestible: The better your pooch can digest the food, the more nutritional value he’ll get out of it. Look for products with animal-based ingredients. For additional support, select options that include supplements with probiotics and/or prebiotic fibers.
No Artificial Additives: Artificial preservatives, flavors, and colors can impact the thyroid and other hormones. Look for natural ingredients like citric acid, rosemary extract, and mixed tocopherols.
Rich in Protein: Protein is a primary nutritional source for canines. It contains the building blocks needed to support muscle mass and function.
Fruits and Vegetables: Fruits and vegetables, other than those identified above as ingredients to avoid, provide digestible carbohydrates dietary fiber to support digestion.
Beneficial Supplements: In addition to wholesome ingredients, there are some supplements that can help support thyroid function:
- Zinc and selenium to support thyroxine function
- Omega 3 fatty acids to support healthy skin and coat
- Biotin to promote hair growth if Fido has a thinning coat
- Probiotics to support gut function
- Milk thistle may be useful to help cleanse toxins from the liver
- Iodine if you make Fido’s food - commercial products should have enough iodine
Probiotics: support your pal’s digestive function and can help to control obesity. They give Fido’s system the tools to suppress harmful bacteria in the gut that can trigger inflammation and diseases.
