Taken from a 'Comment'
I think you should know who was the first ever police dog trainer, he is my uncle Tom Benson, he was called up to the RAF and had trained his dogs he offered them o the RAF but they didn't want them, he then went to the police who not only took the dogs but him aswell. He trained many dogs and men. I am and always will be his proud niece.
(Can anyone supply further details please?)
