A 4-month-old, female Maltese terrier was presented with a 2-day history of anorexia, vomiting, and bilateral ocular discharge.
History. The owners reported that the first sign—diarrhea (initially bloody, then dark)—was noted 4 days earlier, although no diarrhea had been seen the past 2 days. The owners also noticed that the puppy had become depressed and anorexic. The puppy vomited 4 to 5 times over the past 48 hours; each episode was associated with attempts to administer an oral electrolyte and carbohydrate solution. She had been drinking water on her own the past 2 days.
There was no history of previous health problems, a quality diet was being fed, and routine vaccinations had been administered.
Physical Examination. The puppy was depressed with a rectal temperature of 98.7° F; a heart rate of 114 beats/minute; labored respirations at 48 breaths/minute, with an abdominal component and increased bronchovesicular sounds; a bilateral mucoid ocular discharge, with blepharospasm and icterus noted on sclera; a tense abdomen; and marked dehydration.
Diagnostics. The abnormal results of the complete blood count, serum biochemical profile, and urinalysis are shown in the Table.
