Levothyroxine for Dogs: A Comprehensive Guide to Thyroid Hormone Replacement Therapy

Introduction

Levothyroxine is a synthetic thyroid hormone that is used to treat hypothyroidism in dogs. Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone. Thyroid hormone is essential for regulating metabolism, growth, and development.

Levothyroxine is typically given orally, once or twice a day. It is important to give your dog levothyroxine at the same time each day, as this will help to ensure that the levels of thyroid hormone in your dog's blood remain constant.

Monitoring Levothyroxine Therapy

Your veterinarian will need to monitor your dog's response to levothyroxine therapy. This will involve periodic blood tests to check your dog's thyroid hormone levels. The frequency of these blood tests will vary depending on your dog's individual needs.
