Acute hypoadrenocorticism (Addisonian crisis) mimics other critical emergencies, causing cardiovascular collapse that is reversible with prompt treatment.
Addisonian crisis causes acute, dramatic suffering - cardiovascular collapse, profound weakness, and severe electrolyte disturbance. However, the condition is completely reversible with appropriate emergency treatment. Dogs who receive timely IV fluid resuscitation and steroid replacement recover fully and can be maintained on long-term replacement therapy with excellent quality of life. The welfare tragedy is misdiagnosis or delayed treatment causing preventable death. Increased veterinary awareness of the condition - including atypical presentations - saves lives.
