I have a very active 60 pound "mutt" with high energy. He loves this ball! It probably isn't 100% chew proof, nothing is with a heavy chewer, but my dog is more interested in racing around the yard with it than chewing on it. He loves to fetch it, play "chase" with it, push it around in his kiddy pool, and even throw it to himself. He only plays with it under my supervision (which really should be the case with all dogs and their toys) so I think it is going to last a long time. For my dog it has to be an outdoor toy only and is stored outdoors when the dog comes inside, otherwise I could see him throwing it around the house and possibly breaking things. He really flings it sometimes! And it is quite heavy and more on the solid side, not squishy. If it were to hit a precious knick-knack, or a lamp, those things would smash to the floor! The "handle" makes it super easy for the dog to pick it up. It didn't take long for him to figure out that was the way to carry it. He tried biting it at first, but now he just rolls it with his paw until the handle is in a better position for him to grab it, and off he goes.
