Hypothyroidism is the most common endocrine disorder in dogs, occurring when the thyroid gland fails to produce enough hormones, leading to a slowed metabolic rate. While it can affect any dog, it is more frequently found in older dogs and those that have been spayed or neutered.

In some cases, autoimmune reactions cause the immune system to attack the thyroid gland, often triggered by leaky gut, which leads to an extreme immune response. This condition is known as autoimmune thyroiditis.

Signs & Symptoms of Hypothyroidism

Dogs experiencing thyroid issues may display varied symptoms, including:

✔ Recurrent ear infections

✔ Dull or thinning coat

✔ Flaky skin (not red or inflamed)

✔ Toenail infections

✔ Unexpected weight gain

✔ Muscle loss

✔ Lack of energy or lethargy

⚠ Full thyroid blood tests are essential if you suspect your dog may have this condition. Many vets fail to conduct the correct tests, so ensure your dog is tested for T4, T3, and thyroid-stimulating hormone (TSH).

Supporting Your Dog’s Thyroid Health Naturally

Once diagnosed, several lifestyle and dietary adjustments may help manage the condition:

🩺 Liaise with Your Vet

✔ Always consult your veterinarian and discuss the Gut Reset Protocol—especially if your dog is on medication to prevent interactions.

🚫 Remove Bisphenol A (BPA) from Your Dog’s Environment

✔ BPA is found in plastic bowls and toys—replace them with BPA-free options like Lickimat and Sodapups.

🌿 Consider Iodine & Selenium Supplementation

✔ Kelp may help if your dog's iodine levels are low—but only if not already included in their diet.

✔ Selenium supports thyroid function and is naturally present in various foods.

🍠 Eliminate Starch & Root Vegetables

✔ Starches contain phytoestrogens, which can affect estrogen levels and consequently impact thyroid function.

✔ Removing root vegetables from the diet can help maintain hormonal balance.

🧠 Support the Hypothalamic-Pituitary-Thyroid (HPT) Axis

✔ The thyroid works in balance with the pituitary gland and hypothalamus. Supporting gut health and liver function is crucial for proper hormone conversion.

🥩 Feed a Nutrient-Dense Diet

✔ A fresh, whole-food diet rich in healthy fats, proteins, and essential minerals can help regulate thyroid function.

✔ Avoid processed kibble, as it may contain inflammatory ingredients that disrupt hormonal balance.

🏃 Encourage Regular Exercise

✔ Moderate exercise stimulates metabolism and helps regulate hormone production.

🌱 Herbal & Holistic Support

✔ Ashwagandha may help regulate thyroid hormone levels

✔ Milk thistle supports liver detoxification, aiding T4 to T3 conversion.

✔ Adaptogenic herbs can help balance stress hormones, which influence thyroid function.
