Hypothyroidism

Hypothyroidism is a prevalent endocrine disease in dogs, characterized by the underproduction of thyroid hormones, primarily thyroxine. These hormones are crucial for regulating metabolism and energy levels throughout the body. The condition usually results from immune-mediated destruction of the thyroid gland or atrophy of the gland. Symptoms often develop slowly and can be varied, making diagnosis challenging without specific blood tests. While not an emergency, if left untreated, hypothyroidism can significantly impact a dog's quality of life and lead to other health issues. Management typically involves lifelong daily medication with synthetic thyroid hormone.
