My dog gives this 5 stars because she loves to destroy stuffies and this was no exception. She immediately removed the ears and tail, along with the little nubs that were supposed to be nostrils. I give is a few points because she still hasn't removed any legs. I thought it was so cute, and it is far less cute since my dog has had her way with it. She still loves it however…so it is a winner in our book. The photo is after only a couple hours of play
