AIM: To determine the incidence and types of complications associated with oesophageal foreign body (FB) removal in dogs, as well as to evaluate potential risk factors for the development of complications. METHODS: Clinical records were searched within Animal Emergency Service and Veterinary Specialist Services databases between July 2001 and March 2017. Data were collected regarding signalment, FB type, method of removal, medical management and complications. Follow‐up records from the referring veterinarian were then obtained by either phone call or email. RESULTS: A total of 349 FB cases were reviewed. The majority of FBs were bones (77.4%), with Staffordshire Bull Terriers (12.3%) and West Highland White Terriers (9.8%) the most common breeds seen. Complications at the time of FB removal occurred in 20 cases (5.9%), with 14 cases of perforation. Persistent gastrointestinal signs were reported in 4.7% of cases within the initial 72‐h period following FB removal and 11.9% cases outside this time period. Respiratory signs such as dyspnoea and coughing were also reported in 8 cases (2.3%), all of which occurred within 72 h after FB removal. Follow‐up of at least 1 month was available in 151 cases. Delayed complications occurred in 11 cases (7.3%), with stricture occurring in 4 cases (2.6%); 16 animals were either euthanased (n = 14) or died (n = 2) post‐FB removal, resulting in a case fatality rate of 4.6%. CONCLUSION: Use of antacid medications and FB type did not have a statistically significant relationship with complications following FB removal.
