Three dogs survived adrenalectomy 1 dog was euthanatized during surgery because of an inability to achieve adequate hemostasis. All dogs developed ventricular premature contractions before or during anesthesia. In 3 of the dogs, a mass in the area of the adrenal gland was identified with ultrasonography prior to surgery. Three dogs did not have any history of clinical signs of hyperadrenocorticism or pheochromocytoma prior to examination. All 4 dogs were lethargic and weak with pale mucous membranes on initial examination. Diagnosis and surgical management of intra-abdominal or retroperitoneal hemorrhage in 4 dogs with rupture of an adrenal gland tumor were determined.
