Dog-bite injuries to the oral and maxillofacial region are not common. Especially in children, these injuries often involve the facial area. Dog-bite injuries should be treated early to prevent infection and for esthetic restoration. We report the case of a 7-year-old boy who suffered facial trauma caused by a pet dog. A large area of his left side cheek and lower lip were bitten. We treated the injuries, and the postoperative course has been uneventful with good progress.
