(CNN) — An emotional-support dog bit an American Airlines flight attendant Monday, resulting in an injury that required five stitches.
The incident occurred on Flight 3506 from Dallas to Greensboro, North Carolina, operated by partner Envoy Air, American Airlines said.
Medical personnel examined the attendant when the plane arrived. He did not require treatment and was cleared to return to Dallas/Fort Worth, where he received five stitches, the airline said.
American Airlines did not say what type of dog was involved.
Passengers who want to bring aboard an emotional-support animal must provide a veterinary health form and immunization details.
