Bad luck, Randy. Sounds like kids to me. Probably some who've been in your home before. Any dog you can trust around your family can not be trusted to guard the homeplace, imho. They'll put up a show at first, but are too quick to establish a relationship with a stranger, especially if a cookie is involved.

Now if you want home protection, I could rent you my wife's 'attack cat', Hendrix; he hates everybody since she had him fixed!...Geo
