History

A 13-year-old 20-kg (44-lb) neutered male mixed-breed dog was evaluated because of vomiting and anorexia of 5 days’ duration. Physical examination revealed that the dog was approximately 10% dehydrated. A firm, palpable mass was detected in the right cranial aspect of the abdomen. The dog had a body temperature of 40.2°C (104.4°F), respiratory rate of 80 breaths/min, and heart rate of 160 beats/min. A CBC revealed leukocytosis (38,300 leukocytes/μL; reference range, 5,000 to 17,000 leukocytes/μL), characterized by neutrophilia (31,023 neutrophils/μL; reference range, 3,000 to 11,400 neutrophils/μL) with a regenerative left shift (766 band neutrophils/μL; reference range, 0 to 300
