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
Primary hypothyroidism accounts for 95% of cases: lymphocytic thyroiditis (autoimmune destruction, 50%) and idiopathic atrophy (50%). Secondary hypothyroidism (pituitary dysfunction) is rare. Certain breeds have genetic predisposition to autoimmune thyroiditis.
Diagnosis
Baseline total T4 and free T4 by equilibrium dialysis. TSH stimulation test for equivocal cases. Thyroglobulin autoantibodies (TgAA) detect early autoimmune thyroiditis. Complete blood count may show mild anemia and hypercholesterolemia.
Treatment Options
Lifelong oral levothyroxine (synthetic T4) supplementation, typically twice daily initially, potentially reduced to once daily. Dose adjustments based on post-pill T4 monitoring at 4-6 week intervals until stable.
