A 4-month old mixed breed dog presented with a history of acute dyspnea. He was severely dyspneic and hypoxemic on presentation and had a non-cardiogenic pulmonary edema. Electrical burns were discovered on his lips, and a final diagnosis of electrocution was made. He was supported with supplemental oxygen, improved rapidly, and was discharged. The origin of pulmonary edema associated with electrocution is unknown, but it may be part of an acute respiratory distress syndrome (ARDS). ARDS is an important clinical syndrome seen in critically ill patients. It has a poor prognosis and requires prompt identification and supportive therapy.
