How is hyperthyroidism in dogs diagnosed?
An appropriate blood test that detects thyroid hormones can quickly and readily identify hyperthyroidism. Your dog may have a tissue sample removed and examined under a microscope if the doctor discovers a lump in the neck region. Further pet checkups, such as diagnostic imaging, might be essential if a tumor is found to determine its extent.
What treatment options are there?
Depending on the seriousness of the individual case and the underlying factor, there are three main types of treatment utilized to deal with hyperthyroidism in dogs.
The synthesis of thyroid hormones is suppressed by medication when a pet owner selects a non-invasive treatment. The problem often goes away by preventing the body from producing more hormones in the pet. A veterinarian internist can manage hyperthyroidism with the aid of medicines. However, if thyroid carcinoma is to blame, several variables, such as the stage at which it is discovered, will affect the likelihood of recovery.

When a thyroid tumor in a dog is surgically removed, the results are typically excellent as long as it’s easy to move, is less than 4 cm in size, and has not yet migrated to other sections of your pet’s body. Surgery entails the veterinarian’s total removal of the thyroid gland, albeit this is often only done when more than one gland creates problems. This way, the body retains one functioning thyroid gland. The opposite condition, hypothyroidism, may develop if both thyroid glands are removed. Click here to learn more about veterinary surgeries.
Other treatment methods are more comprehensive, necessitating monitoring of animals and their prolonged stay in a veterinary facility. Depending on the stage of thyroid cancer, the size of the tumor, and the degree to which neighboring tissue is affected, other treatments, including chemotherapy, radiation therapy, and iodine therapy, may also be utilized, either alone or in combination.
What is the prognosis for canine hyperthyroidism patients?
The prognosis for dogs with thyroid cancer or hyperthyroidism is favorable when detected and treated early. With the proper care, many dogs can live for one to three years with a good quality of life. Surgery is curative when a benign tumor is present. Treating a malignant thyroid tumor might be difficult and depend on a few factors. However, dogs might develop hypothyroidism after a thyroidectomy, characterized by low thyroid hormone levels. To cure hypothyroidism, dogs need a long-term thyroid supplement.
