A 2-year-old, spayed female basset hound was presented on an emergent basis with a 7-day history of intermittent vomiting, lethargy, and a 1-day history of painful abdomen.
The owners denied any known foreign body ingestion, but did describe routinely giving two brands of compressed vegetable chew treats for dental health. The physical examination revealed normal rectal temperature (102.3° F) and respiration (20 breaths/ minute). Mild sinus tachycardia (132 bpm), a tense and painful abdomen, and a mild elevation in serum amylase levels (1830 IU/L [reference range, 500 to 1500 IU/L]) were found. The rest of the physical examination showed no abnormalities, and the dog's serum electrolytes, renal function, hepatocellular and cholestatic enzyme activities, and complete blood count were all within reference ranges.
Survey abdominal radiographs were done and showed generalized dilatation of small intestinal loops (Figure 1). A barium series was performed after administration of 10 ml/kg barium sulfate by mouth. After 3.5 hours, most of the barium remained within the gastric fundus, and none had passed beyond the proximal jejunum (Figure 2).
