(CNN) – An emotional support dog bit an American Airlines flight attendant on Monday, which resulted in an injury that required five stitches.
The incident occurred on flight 3506 from Dallas to Greensboro, North Carolina, operated by its partner Envoy Air, American Airlines said.
The medical staff examined the assistant when the plane arrived. He did not require treatment and received authorization to return to Dallas / Fort Worth, where he received five points, the airline said.
American Airlines did not say what kind of dog was involved.
Passengers who want to board an emotional support animal must provide a veterinary health form and immunization details.
