    Finally a ball my power chewers cannot destroy
    Size: Medium
    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!

    Perfect for ball demolishers
    Size: Medium
    The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪

    Chuckit medium rebound balls
    Size: Medium
    My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!
