A 7-week-old 1.0-kg sexually intact female Jack Russell Terrier was referred for further evaluation and treatment of tachypnea, intermittent coughing, and signs of exercise intolerance that had persisted since the owner acquired the puppy a week earlier. The owner reported that the puppy was up-to-date on its vaccinations and had received pyrantel pamoate and sulfadimethoxine 2 weeks earlier.

On referral examination, the puppy was bright, alert, responsive, normothermic, tachycardic (172 beats/ min; reference range, 80 to 160 beats/min), tachypneic (60 breaths/min; reference range, 15 to 35 breaths/ min), and had a body condition score of 5 on a scale
