This disease is caused by
the adrenal glands not producing enough cortisone and aldosterone. Symptoms may include decreased appetite, increased thirst,
vomiting, diarrhea, lethargy and weight loss. The dog will require medication for the rest of its life. Dogs are tested for
this disease by a simple blood test. This test does not prove/disprove carrier status. The dog may test clear but could still
develop the disease later in life and may produce puppies with this disease.
