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.

If you were looking for a sign to buy this, here it is
Color: A) Small 2.5" Ball
If you are looking for a ball that can stand up next to a heavy, aggressive chewer.. this is a good choice. Our Pitbull literally destroyed any and every toy that she gets with the exception of one kind of kong ball. She tore through the kong Frisbees, any kind of squeaker toy, and the wobble wag giggle ball (she usually always ends up destroying these but it takes a few weeks. Today she beat her record and had her brand new ball destroyed within the first 30 minutes of us taking it out of the box). But, this ball she has not been able to destroy. I'd like to believe that the Kong ball she has and this ball are made of the same material. Because they are the only balls she can't ruin. And it's not because of a lack of trying. We have watched her sit there and chew with a side of her mouth for an hour or more, trying to make some kind of indention or tear in it and it just never happened. She loves to chew this thing, chase this thing, sleep with this thing. I most certainly recommend this ball. If it is I'ah proof then it is most certainly, 100% a durable ball and worth every penny

Chew King Supreme Chew Toy
Color: B) Medium 3" Ball
So far, freaking amazing. This ball is awesome. I have a 90 lb American Bulldog. Like other reviews. Lot of " indestructible balls" lasted minimum time. Not this one. She even took it to bed with her I bought the 3 inch ball, not the 4 inch ball. The 3 inch ball works amazingly for a large Dog. Yes the 4 inch would be better. So in my opinion, either ball would be fine. As others also said. This ball keeps a active Dog busy for hours. Love to play catch. Love frozen peanut butter in it. One last thing. The price is amazing. I don't see needing to buy another, unless it is lost, because this is made to last. We couldn't be happier.
