Hypothyroidism in Dogs

Are you familiar with hypothyroidism in people? Did you know that this illness can occur in dogs as well? So what is hypothyroidism? It is often referred to as Thyroid Hormone Deficiency and it is an illness that is caused by a low production and release of T4 and T3 hormones in the dog’s thyroid gland. The thyroid gland in a dog should be producing these hormones to help maintain the body’s natural metabolism. Without these hormones, which are also called liothyronine and levothyroxine, the metabolism starts to slow and get out of sync. Hypothyroidism can cause symptoms like lethargy, weakness, unexplained weight gain, hair loss, excessive shedding, poor hair growth, mental dullness, skin infections, intolerance to cold, tilting of the head to one side and even seizures or infertility. Some experts believe this is more common in dogs between 4 and 10 years old that are of medium to large build. Learn more here or call your veterinary clinic Bend, OR.
