I really do not recommend this. I tried it and returned it two days later. I only got it because I live in an apartment and in the winter months, my dog is not fond of the snow or cold (and either am I lol). It was a complete fail and not worth the money! My Yorkie wouldn't even walk on it or go near it. Seemed about half terrified of it. I'm not saying that all dogs will react this way but I'd def skip out on this one. Good concept but does not work. And, it could confuse your dog.
