Hypothyroidism In Dogs
Hypothyroidism is one of the most common hormonal disorders in dogs, yet many pet parents don’t recognize the signs until their dog is already struggling. This condition occurs when the thyroid gland doesn’t produce enough thyroid hormones, leading to weight gain, sluggishness, skin issues, and more.
What Causes Hypothyroidism?
Most cases of hypothyroidism in dogs are due to autoimmune disease (lymphocytic thyroiditis), where the immune system mistakenly attacks the thyroid gland. Other causes include genetics, poor diet, environmental toxins, and chronic inflammation.
Common Symptoms of Hypothyroidism:
Weight gain (even with no change in diet)
Lethargy and low energy
Dry, flaky skin and hair loss
Cold intolerance (seeking warmth, shivering)
Recurrent ear infections
Thickening or darkening of the skin
Slow heart rate
Behavioral changes (anxiety, depression, nervousness)
Certain breeds, like Golden Retrievers, Labrador Retrievers, and Dobermans, are more prone to this condition.
How is Hypothyroidism Diagnosed?
Veterinarians typically run a thyroid panel to measure T4, Free T4, T3, and TSH levels. However, low T4 alone does not confirm hypothyroidism—it can also result from illness, stress, or poor nutrition. A full thyroid panel gives a more accurate diagnosis.
Conventional Treatment
Most vets prescribe levothyroxine, a synthetic thyroid hormone replacement. While effective, it does not address the underlying cause, and some dogs experience side effects like excess thirst, restlessness, or digestive upset.
What Can Pet Parents Do?
While medication may be necessary in some cases, there are many holistic ways to support thyroid health. A fresh, nutrient-dense diet and natural supplements can help manage symptoms and improve thyroid function.
5 Natural Ways to Support Thyroid Health
Feed a Species-Appropriate Diet – Fresh, whole foods support hormone balance better than processed kibble.
Incorporate Thyroid-Friendly Nutrients – Foods rich in iodine (like certain fish and seaweed), selenium, and zinc help maintain thyroid function.
Reduce Inflammation – Chronic inflammation worsens thyroid disease. Adding anti-inflammatory foods like omega-3s and medicinal mushrooms can help.
Detox the Body – Environmental toxins, fluoride in water, and heavy metals impact thyroid health. Providing a gentle detox can support overall wellness.
Use Natural Support – Herbs and essential oils may help balance the endocrine system and support immune function.
