Hulk might be the strongest one there is, but who knows? Your pooch could very well be the one to “out-strong” the Jade Giant from Marvel’s famed collection of superheroes! This $9.99 Hulk Fist Pull Toy is a machine washable dog toy that also comes across as an officially licensed Marvel product. If you have ever played a game of tug with your little pooch, you would know just how much strength it has when it comes to wrenching away a particular toy from you, and not only is it good exercise for both dog and owner, it will also help Fido work out some of the pent up aggression.
