Small, but twisty and fun looking. Seems relatively sturdy, though doesn't look indestructible at all.
Color: Rubber Chew Toy, Size: Large
SLIGHTLY disappointed because I thought this was bigger than it is. If you squish it all in close, it's maybe one and a half times the size of a tennis ball. (Of course, the size is probably listed; I think I just assumed, so my fault.) That being said, it's entertainingly twisty and squishy, though the rubber seems relatively sturdy. I'm not yet positive if it will hold up to the 8 month retriever/lab mix it's intended for; he tends to rip instantly through anything much less sturdy than kong natural rubber. But it seems like something that will amuse him, so we're going to give it a shot at Christmas.

Great product!
Color: Rubber Chew Toy, Size: Large
My dog is an aggressive chewer. I have bought this 3 times for her she loves to play tug and fetch with it. They last longer than most of the other toys I get her and it’s one of her favorites.

It’s okay I guess
Color: Rubber Chew Toy, Size: Large
Good price and decent toy, seems well made. My puppy is entirely uninterested and doesn’t play with it at all.

Very dangerous for chewers!!!
Color: Rubber Chew Toy, Size: Large
My dog was chewing/swallowing the hard rubber within seconds of having this "toy"!!! Not safe, sturdy, no play attraction; only desire was to consume!!!

Get one!

This was my puppy’s fav toy for the longest time. Not too heavy and is the right amount of tough for a chewing teething puppy. Cute toy that’s easy to chew and safe for a teething puppy it’s not loud and lasts. Worth the price.
