Acute hypoadrenocorticism in the dog is a true medical emergency that requires a prompt and accurate diagnosis and appropriate treatment in order to provide for the most optimal outcome. Because the signs of adrenal insufficiency mimic those caused by other more common clinical conditions such as renal failure, intoxications, and various gastrointestinal disorders, it behooves the emergency clinician to always include this condition in the list of differential diagnoses. This paper will review the main elements of this hypoendocrinopathy in order to provide the emergency clinician with the essentials that will be required for appropriate diagnosis and treatment.
