Hypothyroid and Hyperthyroid in Pets

Thyroid gland is located at the front of your pet’s neck. It produces thyroid hormones, very essential for the body metabolism.

Hypothyroidism (low thyroid), in dogs is usually inherited in certain breeds. Middle-aged to older dogs are more commonly affected. The clinical signs include dry, scaly or greasy and thin hair coat, excessive shedding of hair or loss in patches, slow re-growth after clipping and skin pigmentation. Some pets are more susceptible to infections of skin or ears and others may be overweight, lethargic, while sleeping a lot at warm places. Some develop abnormalities in heart rate or even few show neurological signs of jaw muscles and often the breeding dogs may be infertile.

To evaluate your dog’s thyroid gland function simple blood tests or other special diagnostic tests including CAT Scan or Ultrasound can be done. For treatment of Hypothyroidism, supplementation of medication orally or more conveniently mixed in food. Usually the first sign of improvement is often an increase in the activity and alertness during the first two weeks of treatment followed by an improvement or change in their hair-coat in 4-6 weeks or longer, depending on the rate of hair growth. We will ask you to bring your pet in for rechecks of blood levels every six, to access and maintain adequate dose or adjust as needed.

Hyperthyroidism (too much thyroid) in pets is most commonly diagnosed in Cats and is usually associated with tumors of the thyroid gland. In causes weight loss, rapid heart rate, increased appetite or thirst or diarrhea and they can be lethargic or depressed and often vomiting. Sometimes a tumor in the chest is associated with hyperthyroid in cats besides the tumors of glands in the neck. Therefore, not only the blood tests but  also the CAT Scan is done to correctly diagnose (especially tumors). After diagnosis, a proper treatment, either oral, surgical or even radiation is necessary.
