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!
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!!!
