Not for aggressive chewers!
Color: H) Infinity Ring, Color: H) Infinity Ring
Not for aggressive chewers! Done for in about two minutes. I unboxed this and tugged with my Mal for a but then let her have it. Within minutes she had chewed through it. Not worth the money.

Not Quite So Durable...
Color: B) Medium 3" Ball, Color: B) Medium 3" Ball
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.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.
