Abstract Objective Describe presenting signs, diagnostic findings, and magnet‐assisted endoscopic removal method of ferromagnetic gastric foreign bodies (FBs) in dogs. Clinical Presentation Four dogs presented with ingestion of sharp metallic FBs. The presence of gastric FBs was confirmed by abdominal radiography. Results In 3 cases, initial attempts at endoscopic removal were unsuccessful because of ingesta and fluid in the stomach. A magnet contained within a Roth net was introduced endoscopically. Magnet and attached objects were successfully removed from the stomach. In the fourth case, removal with a magnet was judged to be the most expedient method of removal because multiple metallic objects were present. Clinical Relevance An endoscopic technique was used for the removal of difficult‐to‐visualize or multiple metallic FBs. The use of this technique allows the removal of ferromagnetic gastric FBs without surgery or risk of complications associated with the passage of sharp material through the gastrointestinal (GI) tract.
