Addison's disease (hypoadrenocorticism) is a serious endocrine disorder in dogs, but with correct diagnosis and lifelong management, affected dogs can achieve excellent quality of life.
The welfare burden of Addison's disease lies primarily in the diagnostic journey. Dogs with chronic, waxing-waning signs of lethargy, vomiting, and weakness are often treated for gastrointestinal or other conditions before the correct diagnosis is made. During this period, suffering accumulates. Once diagnosed, treatment is highly effective — the welfare transformation from recurrent crises to stable, comfortable life is dramatic. Owners must be educated about crisis recognition and carry emergency injectable corticosteroids. Stress dosing during illness or surgery prevents iatrogenic crises. The psychological burden for owners managing a condition requiring lifelong vigilance can be significant, and veterinary support for owner education is a welfare enabler.
