Anecdotal observation at the authors\u2019 institution suggests that patients receiving maropitant citrate occasionally display sonographic and radiographic signs of diffuse functional ileus. The goals of this prospective one\u2010group pretest, posttest study were to determine if administration of maropitant citrate caused changes in ultrasonographic wall thickness and peristaltic rate at the pylorus, duodenum, or jejunum and\/or a radiographic change in intestinal diameter or appearance. Twenty\u2010one healthy adult dogs (ages 1\u20138 years) were recruited. After overnight fasting, abdominal radiographs and a brief gastrointestinal ultrasound were performed at time 0 (baseline), followed by a 1\u00a0mg\/kg subcutaneous dose of maropitant citrate. Imaging was then repeated 1 and 3\u00a0h post maropitant administration. Peristatic contractions and wall thickness at the pylorus, duodenum, and jejunum were measured with ultrasound, and radiographs were assessed for signs of functional ileus (mild diffuse dilation of the small intestine or mild increase in overall small intestinal gas content). Significant decrease in rate of peristalsis of the pylorus (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0&lt;\u00a00.001,\n                    <jats:italic>hp<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u00a0=\u00a00.48) between 0 and 1\u00a0h and between 0 and 3\u00a0h and jejunum (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0&lt;\u00a00.02,\n                    <jats:italic>hp<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u00a0=\u00a00.48) between 0 and 1\u00a0h was found after administration of maropitant citrate.
