Plain-English summary
A 1.2-year-old Pug was brought to the vet for vomiting, constipation, and a swollen belly. After some tests, the vet found that the dog's intestines weren't moving properly, which caused gas buildup and discomfort. During surgery, they discovered severe damage to the muscle cells in the intestinal wall, leading to a diagnosis of intestinal pseudo-obstruction, a rare condition that affects how the intestines function. Treatment options may include dietary changes and medications to help manage symptoms, but the specific outcome for this dog wasn't detailed.

Abstract
Intestinal pseudo-obstruction is a rare disorder that affects gastrointestinal propulsion. It may be secondary to several pathological conditions or it may develop without a known cause. A 1.2 year-old intact Pug bitch had a history of vomiting and constipation, which were followed by diarrhea and distended abdomen. Hypomotility and dilation of the small intestine, which was filled with gas, were observed during laparotomy. Histologically, full thickness biopsy specimens demonstrated a severe loss and degeneration of leiomyocytes in the inner and outer muscular layers of the intestinal wall, whereas there was a marked hypertrophy and hyperplasia of smooth muscle cells in the lamina propria, and extremely thickened muscularis mucosae arranged in bundles oriented in different directions with marked hypertrophy and hyperplasia of leiomyocytes. Distribution of leiomyocytes was further characterized by immunohistochemistry. These findings support the diagnosis of intestinal pseudo-obstruction in a Pug, associated with degeneration and loss of leiomyocytes in the muscular layer.
