This was recommended by our trainer and it worked great for calming our Chihuahua down, we noticed a change right away. We continue to put a new one on when ever the dog starts acting up.

I have a very nervous chihuahua and thought I'd give this a try on our last trip. It really worked. I can't believe it.
