Is your dog calm and gentle until he sees a cat or postman, at which time he turns into a wild-eyed angry green monster? What you need is the Hulk Fist Pull Toy to keep Fido distracted and busy, and help him let off some steam by chewing up the Hulk’s fist. This is an official licensed Marvel toy, and it’s machine washable so that Fido can keep making a mess of it and you get to do the good part of cleaning it up all over again.
