The situation is worse then people imagine.Several years ago a destruction order was obtained under the 1871 Dog Act against two dogs that had bitten a young boy who had trespassed into a private garden.This effectively means that any dog can be destroyed as a dangerous dog no matter where it is .Even if as in the case in Kent the dogs were in the owners own back garden and that the boy had to climb a 5 foot wall in order to get into it.
