Query: No match for a puggle.

I have a puggle who, as adorable as he is, continues to be one of the most untrainable, stubborn and clever dogs I've ever encountered. I was told by a friend that this Scat Mat will help me stop him from going into my downstairs family room area. He goes down there every chance he gets to forage for food, or chew something, or go trash picking. He's very smart and listens for when someone leaves the room and doesn't close the door. So I bought the Scat Mat, and the extension, hoping a few good zaps would discourage him. He got zapped once, he barked, then added a little howl of dismay. He sniffed it, then backed up, got a running start and nimbly jumped over the mat and the extension mat. He figured it out in about 30seconds. Epic failure. Scat Mat will be returned.He's a clever little bugger. Maybe it works on other dogs, but not my puggle.
