Correct signage and complying with local bye-laws will go some way to
protect your rights, however even if you put up a 30 foot high "beware of
the dog" sign, if an intruder is savaged by the pet poodle you can still
be
sued.... and the court can rightfully force removal of the deterrent - in
that case, destroy the animal.

Unless of course you are a royal personage with a bull terrier.
