Won't go through "hurricane" or chain-link fencing - dogs LOVE it.
Color: Orange, Size: Large
We've been using this size (large) for about 2 years now. Between our Doberman pinscher and the boxer-pitbull mix, they are tough on toys. These dogs have access to the Chuckit Ultra balls only under supervision and they run like crazy in the backyard while either fetching or holding onto the balls. It keeps our doberman out of trouble because she's running with a ball in her mouth and therefor cannot nip at the other dog when she gets overly excited. Tennis balls are lucky to last one play session with these guys, just for comparison purposes.
When throwing the regular size, the ball occasionally went right through our backyard (chain link aka "hurricane") fence -- even though they shouldn't quite fit. The size large balls bounce off the fence; our only problem now is when one of the dogs does a soccer style head-butt and knocks the ball over the fence that way.
After 2 years, one ball has a split down the side and two are discolored because they were left outside when we couldn't locate them after a play session. Overall I like these very much and appreciate how well they've held up.

My dog and I love this!
Color: Orange, Size: Large
The balls are larger and fit the Chuck It with the larger ball size perfectly. The balls are hard rubber material and have stood up to continued chewing after our dog picks them up. They bounce and are really hard wearing. Great product for the price!

Durable but don't give this to them as an everyday chew toy.
Color: Orange, Size: Large
My Catahoula loves these things. Great for a training aid and to let them get their zoomies out but not durable enough for an idle chew toy.

Great for dogs that love cat toys
Size: Small - 2 Count (Pack of 1)
I have a 45# dog who loves to play with cat toys. She's a strange one, but it's what she likes. She also loves ChuckIt balls (glow in the dark, squeaker, rubber, etc.). We bought 2 2-packs and we're glad we did. These are about the side of ping pong balls or golf balls. Yes, if your dog's an aggressive chewer or smaller than a teacup these will probably not last long. Yes, my weirdo dog almost immediately picked all the "fuzz" off the ball because that's what she does. The quality and durability of the ball haven't been affected, it's just a bald little ball. Highly recommend for any non-aggressive chewers that LOVE cat-sized toys.

Not very durable
Size: Small - 2 Count (Pack of 1)
I purchased some of these balls a while back and had forgotten how quickly my yorkie puppy was able to destroy them.. I recently ordered some more bc I saw them on sale. I now have another yorkie pup that also loves to play ball. They actually play ball with each other. Within 24 hrs, the balls are fraying and they are getting choked on the fuzzy s off the balls.
I'm not going to bother to return 3 2pks bc they were so cheap. Now I know why.
