    So Far So Good
    I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.

    My dogs favorite!
    My dogs love these! They will play all day if you'd let them, these balls are their favorites. I use the chuck-it handle and they get tons of exercise in the big yard!

    The Dog LOVES IT!
    I bought this for my ex-wife's Pitbull. He is an aggressive chewer and usually destroys any toy I buy him. But not this one! The ball is small enough and pliable that it gives when he chomps on it. He loves this ball and seems to be his favorite toy. Thank you for making a product that he likes and can't destroy!

    My Golden Retriever’s favorite
    We’ve owned lots of toys and balls. This specific version (in blue) has been her absolute favorite. She’s about 72lbs and chews on this thing regularly with no visible damage. We actually own about 6 of them because they have a tendency to go missing underneath furniture and in the yard. We have two of the orange colored ones but she doesn’t like those nearly as much which I assume is because the blue is easier to see in the grass. Other than that…They bounce really well and also whistle a little when you throw them hard enough. I hope they never stop making these.

    doesn't whistle as loud as other chuckit balls I've seen, but a good ball.
    makes some noise, but I've seen (and played with) others at the dog park that whistle much louder than the 1 I got. all Chuckit balls... so, just this one I'm betting. but it flys good and the dog loves to chase it. he chews it a fair bit as well and the ball has not taken much damage from him (lab mix) or others that have had a go at it. I'll likely buy another at some point ... just wish it was a little louder when flying.
