If they came round here, our GSD who was bred for the police force, would not ask any questions. As one scrap man said, as he poked around "OMG he has a head the size of a football - is he loose in the yard at night?" He then beat a hasty retreat, never to be seen again.
Its not right, scum bags like this helping themselves, and it makes you wonder, if they run over a dog, are they capable of doing the same to a person should they get in their way?
We have had a lot of quad bike thefts here. Thieves have been breaking into outbuildings and then making off across fields, to a waiting trailer.
