Great product
Color: Multicolor, Color: Multicolor
I have three aggressive, chewing dogs that absolutely love these bones. I've had them for a couple of months and they have yet to break them or damage them. Lots of chewing left.

Great for aggressive chewers!

Great for aggressive chewers!! My grand-dog loves it. It is slightly heavy, perfect for him. It definitely cleans his teeth. He plays with it all the time.
