Let the dog bite them.. then shoot them. Problem solved.

If you would like to defeat any lawsuit against your dog biting someone on your property.. I'm serious about this. Post a 'Beware of Dog' sign.. I'm not kidding about this.. I can't tell you how many dog bite cases we've had on private property.. the insurance company will literally send us a picture of the sign posted on the property.. take a date stamped pic as well..

It serves as notice for people not invited on your property. Now if you invite someone and your dog bites them that's a different story.
