And there is no dog that can't be trained as John proves day-in day-out at his training centre in Codsall Wood.
John's interest in dogs began when he was twelve years old after watching a display from RAF dog demonstration team.
He initially wanted to go into the police force but was half an inch too small so he opted for the RAF.
His three dogs, Tilly, Jimmy and Daisy are always undergoing some kind of training with Jimmy currently learning weave poles and jumping.
John has a degree in Canine Behaviour and training and is soon to appear in Animal Heroes documentary due to transmit on June 4th as well as a Churchill commercial.
