Butterbean is a 65 lb pitbull, and he's had the large jolly ball for 3 years and it's still his favorite toy. After all this time he just managed to get the ball out of the inside! Worth every penny! If the large was available, I would definitely be ordering it!
This toy is a lot of fun, but watch your dog play with it. It is for your dog to tear up its gums on the plastic as it tries to chew its way to the ball. I have to take it away after ten minutes because he's managed to bloody himself. It's not a big deal or a lot, but just to be safe. If your dog is a chaser and not a chewer you will be well off.
