Canine hypoadrenocorticism requires lifelong mineralocorticoid and glucocorticoid supplementation. With good monitoring and owner education, most affected dogs maintain excellent quality of life for years, but acute adrenal crises require emergency intervention.
Well-managed Addisonian dogs live comfortably with normal life expectancy; the welfare challenge is preventing acute crises through consistent medication and appropriate stress dosing. Owners must understand that any febrile illness, surgery, or significant stress requires immediate dose escalation and veterinary communication. Dogs that experience repeated crises from inconsistent medication suffer acute distress from severe electrolyte abnormalities and cardiovascular collapse. Welfare-centred management includes comprehensive owner education, a written crisis protocol, a medical alert tag, and relationship with an emergency practice familiar with the dog.
