Dog loves it!
it's crinkly and squeaky, both things the dog loves. You can stuff treats in the mouth as there is a sort of treat pocket in the alligators 'belly', but my dog has a long skinny snout so he got the treats out fast. Other dogs with narrow snouts might not benefit from the treat pocket either.
My only complaint is the teeth are made out of a woven fabric that shreds very easily, I'll just cut them off.
