Reference:
I was told by the police that if you have a dog on the premises and do not have signs up, if a burglar breaks into your home and gets bitten by the dog the dog can be destroyed (and burglar can sue the owner) - how mental is that? But apparently it's because there was no prior warning. (Maybe I need to put a sign up saying 'enter this house unvited and you'll get shagged with a breadknife' just to make sure I'm covered too then)
Heard so much stuff about this over the years. I have one GSD now, but bred and showed them for a number of years.
I was told by a police officer that having 'Guard dog' signs on my gate was more or less admitting that I owned a dangerous dog - which was against the law.
Not that I give a damn, the signs are still there. Often wonder, if anyone tried to break in, who'd get to them first, me or the dog...
The GSD definitely isn't on the Dangerous dogs list - although as we all know, in the wrong hands any breed can be dangerous, even the smallest.
