My Chihuahua puppy had one of these which he loved and played with daily until he bit a hole in the heal. I had paid significantly more from alternative seller than this one was on sale for from Amazon. My local supplier didn't have any more in stock so as an after thought I tried Amazon and was very pleased to see that they not only sold the slipper but also that it was a lot cheaper than the first one I had purchased. My puppy loves it and you can tell he thinks he is very clever when he managed to make it squeak. Highly recommended.
