Inclusion criteria were endoscopic identification of gastric polyps; dogs with primary gastric neoplasia were excluded. Signalment, clinical signs, history of proton pump inhibitor administration, endoscopic findings, histopathology, treatment, complications, and follow-up data were collected. Endoscopic polypectomy was performed using cold biopsy forceps or electrosurgical snare.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sc_a3\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Over a 5-year period, 57 dogs were included from 574 canine gastroscopies performed, yielding a detection rate of 9.9% (57 of 574). Polyps were solitary in 54.4% and multiple in 45.6% of cases, mainly located in the gastric antrum (77.2%). All polyps were hyperplastic on histopathology. Endoscopic polypectomy was performed in 17 of 57 dogs, with no intraoperative complications. Mild postoperative complications occurred in 5 of 17 dogs. Clinical signs resolved in all but 1 case and remained absent during follow-up (median, 16 months). Polyps removed with electrosurgical snare were significantly larger than those removed with cold biopsy forceps, with an exploratory cutoff of 10 mm distinguishing between the 2 techniques. No recurrences were documented based on clinical follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sc_a4\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Gastric polyps in dogs are uncommon lesions, typically hyperplastic and associated with chronic inflammation.
