Iodine is an essential trace element for a dogs’ health, a dog’s thyroid requires this chemical element to produce the critical thyroid hormones thyroxine (T4) and triiodothyronine (T3). Thyroxin contains 4 iodine atoms while triiodothyrionine has 3, this characteristic is indentified in the abbreviation T4 and T3. T4 and T3 are produced by the combination of the amino acid tyrosine and iodine in the thyroid gland, these substances are stored in a protein called thyroglobulin. A dog’s thyroid gland actively absorbs iodide from their blood after processing the iodine into vital hormones it then releases these hormones into the blood, actions that are regulated by a second hormone TSH from the pituitary. Once these hormones enter the blood system they regulate a dog’s metabolism and oxygen consumption of tissues at the cellular level.
