Introduction to Low Thyroid Levels and Skin Issues in Dogs
Low thyroid levels, or hypothyroidism, is a condition that affects dogs of all breeds and ages. It occurs when the thyroid gland, a small gland located in the neck, fails to produce enough thyroid hormone. This hormone is responsible for regulating metabolism, energy levels, and overall body function. When the levels of thyroid hormone are too low, it can result in a range of symptoms, including skin issues. In this article, we will explore the link between low thyroid levels and skin issues in dogs, as well as the causes, symptoms, diagnosis, and treatment options for this condition.
Understanding Thyroid Function in Dogs
The thyroid gland in dogs produces two main hormones: thyroxine (T4) and triiodothyronine (T3). These hormones are responsible for regulating the metabolism, energy levels, and overall body function. The thyroid gland is controlled by the pituitary gland, which produces thyroid-stimulating hormone (TSH) to stimulate the thyroid gland to produce T4 and T3. When the levels of T4 and T3 are too low, it can result in hypothyroidism, which can cause a range of symptoms, including skin issues.
Causes of Low Thyroid Levels in Dogs
There are several causes of low thyroid levels in dogs, including genetic predisposition, autoimmune disease, and damage to the thyroid gland. In some cases, the thyroid gland may be underactive due to a lack of iodine in the diet, although this is rare. Certain medications or treatments may also affect thyroid function. In dogs, hypothyroidism is most commonly caused by autoimmune disease, which occurs when the immune system attacks the thyroid gland and prevents it from producing enough thyroid hormone.
