Addison’s Disease or Hypoadrenocorticism is caused by a deficiency of the adrenal gland hormones. It is an endocrine condition which is brought about an abnormal decrease in the body’s production of cortisol and aldosterone. One of the most common causes of Addison’s disease is the destruction of the tissues of the adrenal gland which is brought about by an autoimmune disorder. Other potential causes include cancer, certain medications, infections, and health problems that interfere in pituitary gland function. Dogs that are on long-term steroid therapy and stop abruptly are also at higher risks of adrenal gland tissue damage, which can lead to the so-called ‘Addisonian Crisis’. This is an important reason why there is a need to taper off the dosage of steroid medication.

There are dogs that are genetically predisposed to Addison’s Disease. These breeds include English Springer Spaniel, Airedale, German Sphepherd, Wheaten terrier, Portuguese Water Dog, Great Dane, and Standard Poodles.
