Not so much
Size: Small (Pack of 1)
My Pup likes other chew bone from this company, but not so much this shape. *As with all these type THROW them away when they become too chewed up*! Pieces of nylon aren't meant to be eaten..

Love it
Size: Small (Pack of 1)
We adopted our pup and the only thing that came with her was this toy. She loves it!!! Of course we have to purchase a new one about every 3 months, when the plastic starts crumbling.

Amazing chew product!
Size: Small (Pack of 1)
I use these for my large dogs. Both dogs love them! And the first two survived our two pups first 10 months. I just reordered and they were excited and immediately began chewing! Highly recommend.
