Having been through a similar situation, where 2 of the neighbor's dogs dug under HIS fence to get into my yard, attacked a puppy I was sitting and nearly severed my wrist. We have a "one bite" dog law in Pa, so he has his dogs back under major regulations, as he was found guilty in criminal court. Sorry to frighten you, but I have a huge law suit in litigation and I don't care if the idiot loses his house. He never ever checked his fence. I blame the owner, not the dogs, I'm sure the pup was prey to them. My life is ruined in a lot of ways. Since no human was injured, I don't know what your state's laws are, but I'd hunker down the hatches.
