Overview
Thyroid hormone replacement therapy is vital for pets suffering from hypothyroidism, primarily affecting dogs and occasionally cats. This therapy involves administering synthetic thyroid hormones to normalize metabolic function.

Thyroid hormone replacement works by supplementing the body with synthetic hormones, such as levothyroxine, which mimic the naturally occurring hormones produced by the thyroid gland. This helps regulate metabolism, energy levels, and overall health.
Uses & Indications
