Cassie the Sheltie loves the JW Dogs in Action toy that looks like a section of DNA or a twisted ladder. We own 3 of them in case one fails or we lose it or... It is moderately predictable in its action when thrown, and also makes a good tug toy. But THIS Football is crazee. Where it will end up, nobody knows. Ramps up the game. Not as rewarding as a tug toy, because of the flex in the DNA one, but her choice when she wants extra fun in the chase. Shelties aren't known for their powerful jaws, but she hasn't destroyed anything yet. Should work for any small breed.
