Acute Addisonian crisis causes cardiovascular collapse requiring immediate emergency treatment, with welfare outcomes depending entirely on rapid recognition and intervention.
Addisonian crisis causes acute, severe cardiovascular distress. The collapse of both glucocorticoid and mineralocorticoid function simultaneously means dogs experience the equivalent of circulatory shock - weakness so profound they cannot stand, cardiovascular insufficiency, and potentially fatal electrolyte imbalances. The terror of sudden physical collapse without any apparent cause is distressing. The dramatic recovery with appropriate treatment - dogs that arrive on a gurney often walk out hours later - demonstrates both the severity of crisis and the effectiveness of intervention. Preventing crisis through consistent medication and stress-dose supplementation is the welfare priority.
