Hypothyroidism is also known as underactive thyroid. It is a condition where the thyroid gland, which produces hormones,   Thyroxine (T4) and Triiodothyronine (T3),  is dysfunctional and not producing these hormones as required by the body. T4 and T3 are hormones that control the bodies metabolism.

Thyroid dysfunction including the most common, hypothyroidism, is a relatively common endocrine disease in dogs. The thyroid is a complex gland and results can be adversely affected by:

  • vaccination;
  • other drugs;
  • diet supplementation;
  • seasons;
  • other non thyroid related illness; and
  • general wellbeing.

Therefore,  issues concerning the thyroid are also considered to one of the most misdiagnosed.
