I wanted my pup to love this. However, because it was backordered, by the time we got it he was already crate trained, so it’s not been too useful in that regard. He also doesn’t seem too interested in it in general, even with peanut butter on it. I dislike using the peanut butter anyway as it’s kind of a pain to clean out if he doesn’t finish it. I wouldn’t buy again... frozen carrots work best for us.
