Description: Hypothyroidism is an endocrine condition that the body doesn’t make enough thyroid hormone. It is often caused by autoimmune responses and typically occurs in middle-aged dogs.  

What to Watch For: Signs include dry skin and coat, hair loss, susceptibility to other skin diseases, weight gain, fearfulness, aggression, and other behavioral changes. 

Diagnosis: Your veterinarian will conduct a blood screening test annually to screen for the disease. 

Treatment: Hypothyroidism is easily treated by administration of a synthetic thyroid hormone called thyroxine. Doses vary by the animal's weight and severity of the case. The pet will need regular administration of the hormone for the rest of their life.
