Letters magnet was removed from the stomach via a single gastrotomy incision; the necrotic area was resected and then closed with a two-layer inverting seromuscular pattern (3-0 polyglyconate). The dog recovered well from surgery without any postoperative complications. In order to minimise the risk of gastrointestinal complications caused by magnetic attraction it is suggested that if multiple, small, metallic foreign bodies are seen on abdominal radiography these should be monitored frequently with serial radiography. If they are found to be nonprogressive or there are signs suggestive of peritonitis, an exploratory laparotomy should be performed immediately (Kiefer and others 2010).
