What is the thyroid gland?

The thyroid gland is a small endocrine gland that secretes important hormones in your pet. The main hormone produced by the thyroid gland is thyroxine. Thyroxine is known medically as T4. Thyroid hormones help control heart rate, body temperature, and how quickly the body burns calories.

What happens when the thyroid gland malfunctions?

  • hyperthyroidism it occurs when too much thyroid hormone is produced. Hyperthyroidism is rare in dogs, but occurs more often in middle-aged and older cats. Symptoms include weight loss, increased urination, and increased thirst.
  • hypothyroidism It occurs when the thyroid gland cannot produce enough thyroid hormone. It occurs most commonly in dogs and rarely in cats. Symptoms include weight gain, lethargy, hair loss, and a slow heart rate.
