For dogs with hypothyroidism, it is important to provide them with a diet that is low in iodine. Iodine is an essential nutrient for thyroid hormone production, but dogs with hypothyroidism have an underactive thyroid gland and need lower levels of iodine. There are several dog food options that are specially formulated for dogs with hypothyroidism. These foods typically contain limited amounts of iodine and are also rich in nutrients that support thyroid function, such as selenium and zinc. Some popular brands include Hill's Prescription Diet y/d, Royal Canin Veterinary Diet Canine Thyroid Health, and Purina Pro Plan Veterinary Diets NF Kidney Function Canine Formula.
