Color: Rubber Chew Toy, Size: Large, Color: Rubber Chew Toy, Size: Large
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.

Airedale tough!
Color: Rubber Chew Toy, Size: Large
We have two young Airedale Terriers and I thought this would be a good inside toy for them to tug. And I was right! Very happily so. I have to admit I was surprised when I first saw it; it seemed so small. But the thing stretches and springs back to shape. We’ve had it about 2 weeks now and it is constantly played with. Absolutely the best toy! Very interactive either alone (it rolls) or with us or they play together. I am surprised how tough it is with all the constant rough play. Highly recommend!!!

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.
