Maybe I have a SUPER aggressive chewer...he went through this ball in under a week. I originally bought the ball because of a review that stated the owner's Pitbull had the same ball for two years; not so much for my Rottweiler. He started chewing off and swallowing small crumbs from the ball within a day or two. By the end of the week, it was chunks so I had to toss it in the trash to prevent an intestinal obstruction. On the up side, my Rottweiler LOVED the ball while it lasted. However, I can't, in good conscience, give this ball a rave review based on this experience. Please take this review with a grain of salt as I have yet to find ANY toy that my boy won't DESTROY in a week or two. I hope that someone finds this informative when searching for chew toys for SUPER aggressive chewers like mine.
