Indestructible bully toy
Color: Blue
We have a bully that chews through everything, believe it when I say, he loves this n it is still in one piece. Where I put treats in it or not. He’s also able to play tug of war with is brother with this toy. I will be buying additional ones!

Durable, Dogs love it
Color: Red
My Frenchie is a crazy chewer and can chew up a nylabone in a day, so I was looking for something that would last longer. So far this is holding up, and is pretty durable. Both my dogs like it a lot, it’s easy for them to grasp, and chewable but still very tough material. I suspect at some point it’ll wear down, but not for a while. The size was just as described / expected. Not too small and not too big

NOT FOR PLAYING CATCH.
Color: Blue
This toy is quite heavy, making it good for a chew toy or for fetch, but not for catch. It could very easily injure your dog as it damned near did mine.
