"My family adopted a rottweiler puppy several months ago. Last Friday, two men rang my doorbell and attempted to sell me a new roof. My rottweiler bit one of the salesmen. He came back yesterday and is claiming I am responsible for his injuries. I told him to get lost and slammed the door in his face. It's his fault he got bit. I never told him to come on to my property and hassle me. My dog was just protecting me because he made a move towards my front door. He also missed the no trespassing sign on my mailbox. It may be a bit faded,  but it says no trespassing. The salesman is now threatening to get a lawyer to sue me. Am I responsible? Is it his fault or mine? Should I pay him to make him go away?"
