Plain-English summary
A group of 40 dogs with gastrointestinal bleeding, either obvious or uncertain, underwent a procedure called video capsule endoscopy to help find the cause. The procedure involved swallowing a small camera capsule, which was able to identify bleeding lesions in 24 of the dogs. However, the quality of images from the stomach and colon was often poor, and many studies were incomplete, especially when the capsules were given orally. Factors like certain medications and pre-existing digestive issues made it harder to get complete results. Despite these challenges, the procedure was useful for diagnosing bleeding issues in dogs.

Abstract
BACKGROUND: Prospective studies describing video capsule endoscopy (VCE), its feasibility, and complications in dogs are limited. OBJECTIVE: To assess VCE, quality of visualization, complications, and risk factors for incomplete studies in dogs with overt or questionable gastrointestinal bleeding (GIB). ANIMALS: Forty dogs with overt or questionable GIB. METHODS: Prospective, multicenter, interventional study. From August 2017 to March 2020, dogs were examined by VCE (ALICAM) because of overt or questionable GIB. Reported outcomes included diagnostic results of VCE study, quality of visualization, and complications. Risk factors for incomplete studies were evaluated using logistic regression. RESULTS: In total, 40 dogs (13 overt, 27 questionable GIB) were included. The capsules were administered PO in 29 and endoscopically in 11 dogs (6 duodenum, 5 stomach). One capsule was not retrieved. In 24 of 39 recordings, bleeding lesions were identified (10 overt GIB, 14 questionable GIB). Overall, the quality of visualization was poor to limited in the stomach and colon, and adequate to good in the small intestine. The most common complication was an incomplete study in 15/39 studies, particularly after oral administration (13/28). Risk factors for incomplete study after oral administration included administration of simethicone or opioids, chronic enteropathy, and capsule gastric transit time >6 hours. CONCLUSIONS AND CLINICAL IMPORTANCE: Video capsule endoscopy can be used to diagnose a variety of lesions causing bleeding in the gastrointestinal tract of dogs with questionable GIB. Incomplete studies are the most common complications in dogs after oral administration of capsules.
