Our trainer told us about
these mousetraps - I cannot recommend them highly enough! They don't hurt the dog, but they do scare him and are not pleasant. We used them on a six week old puppy without problems.
You simply place them on the couch, in shoes, on books - whatever you want him to leave alone and they will teach him to stay away. As soon as he touches the large hair trigger trap, it snaps shut but there's no metal item to bite into them and it doesn't pinch so hard it would hurt. I think it must work on mice by suffocating them.
I would suggest you set these on the couch and your dog will learn to stay away quickly.
