The collie named Dart got away from United Airlines' pet transport service yesterday morning. It threaded through traffic and several parking lots before ending up stuck in the mud in a swamp.
Airport police used a rowboat and snare to reach the dog. Dart was not injured during the 45-minute rescue.
The dog was cleaned up and reunited with his owner to make its flight.
Airport officials were unsure where in Asia the owner and dog were headed.
