About Hypothyroidism

Hypothyroidism is the most common endocrine disorder in dogs, resulting from inadequate production of thyroid hormones (T3 and T4). The thyroid gland regulates metabolism, and deficiency affects virtually every organ system. Most cases (95%) result from immune-mediated thyroiditis or idiopathic thyroid gland atrophy.

Causes
