The man, who is in his 40s, was attacked in Pasley Park, southeast London, on Friday.
He was taken to hospital with injuries to his arm. The owner of the dog, believe to be a grey-coloured XL bully, left the scene before police arrived.

Met Police officers were called to the scene by the London Ambulance Service, the force said in a statement.
