Hypothyroidism is a common endocrine disorder in pets, particularly dogs, where the thyroid gland fails to produce enough thyroid hormone. This deficiency can lead to a variety of symptoms such as weight gain, lethargy, hair loss, skin problems, and intolerance to cold temperatures. With proper medication and monitoring, pets with hypothyroidism can lead happy and healthy lives. Regular check-ups and a tailored care plan are crucial in providing the best support for pets dealing with this condition.
