No signs of any kind here. The dogs make their own presence known. I follow the same premise as with my CCW: be armed, be ready, be discreet. As far as the "beware of dog" signs, different areas may be different, but here, if that goes to a court proceeding, that is an admission that your dog will bite. Most people prefer the signs more along the lines of "keep gate closed, dogs may be loose in yard".
