The owner will be lucky an attorney does not sue him. You cannot boobytrap your property. Even with warnings. With dogs that out of control he is grossly negligent for not keeping them locked inside. Sure if someone breaks into his house that is one thing, but walk up the front path to the door? The mailman will be next.
I’m sure the owner will get sued, and no doubt the dogs will be put down. All because some stupid twit ignored the warnings and went where she wasn’t wanted. So it goes.
