Addison's disease is a potentially fatal hormonal deficiency that, once diagnosed and managed, allows dogs to live normal, comfortable lives.
Addisonian crisis causes profound, terrifying physiological collapse. Before diagnosis, dogs may experience multiple episodes of vague illness attributed to other causes. The welfare impact of undiagnosed Addison's is months of recurrent unexplained illness punctuated by potentially fatal crises. Once diagnosed, the welfare transformation is dramatic - consistent medication enables these dogs to live completely normal, active lives. The key welfare challenge is recognition: Addison's is called the great pretender because it mimics so many other conditions.
