I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.

My dog LOVES this ball

Size: Medium, Size: Medium

Does your dog destroy tennis balls in seconds? Yes? Then your dog NEEDS this ball! It's squishy like a tennis ball, fits in ball launchers (even the cheap ones) and bounces when it hits the ground. My dog has been literally playing with this ball all day and not a single mark on it! The only bad thing is that it does not float. Definitely worth the money! Put it in your cart!
