A 5-year-old, intact female, Pomeranian was presented with a persistent vomiting for 5 days after swallowing a chicken bone. The dog was diagnosed with an esophageal foreign body, and a small perforation was found after the endoscopic removal of the chicken bone. The dog was determined to be treated with a non-operative management, and a complete closure of the perforation was confirmed by a flexible endoscopy 3 weeks after removal of a chicken bone. This paper reports the case of esophageal perforation caused by foreign body in esophagus managed with the non-operative therapy instead of surgical correction.
