I waited to write the review on this because I wanted to see how long it lasted. JW toys have typically been very sturdy and withstood significant chewing by my super chewer pit bull. The best toy he's had was the Bad Cuz devil ball by JW...once he chewed the feet off of it the rest remained intact for months and months. I was hoping for the same effect with this ball (sans feet), but no such luck. The squeaker broke within the first hour of play, which I expected and don't really care about (why even put squeakers in toys? they NEVER last more than a day with just about any dog).
My boy absolutely LOVED this ball. For about 3 weeks it was his favorite toy. He plays fetch a little bit, but mostly just wants you to chase him around with the ball in his mouth while he squishes it around in there, then he'll lay down and chew away for a long time. So the ball withstood several long chew sessions, but after about a week it had a crack in it, and a couple weeks later he managed to break a chunk out of it. I'd say about 3/4 of the ball is still intact and floating around the house. It's no longer his favorite (I think once he cracks a toy open the fun is gone), but he'll still grab it and run around the house with it for a while and occasionally do a bit of tug-o-war with it.
I think it would be a great ball for a dog that isn't such a powerful chewer. I might buy one again someday, but I'll try other things first in an attempt to get something more durable that will last longer.
