Saying "owners should have more responsibility" is an utterly meaningless platitude. As I mentioned previously I represented many dog owners in dogbite cases and every one of them that I can remember was as responsible as any dog owner I know. There was nothing they could have done to prevent what happened in my mind. I have represented many dog owners who acquired their pets as rescued animals at shelters. It is possible the dog was abused by a prior owner but how is that my client's fault? They gave the dog a home and did the best they could and got rewarded with a lawsuit after their dog bit the guy delivering a package they were not expecting. That client put the animal down. With the rescues they get put down as the owners can no longer trust them. I would say a large % of my dogbite defenses were on rescue dogs who may or may not have been abused prior to my clients' ownership. If someone thinks owners should be doing more in this situation what more should they do?
