Dog is Happy!
Color: 3PC-Peanut Butter-Green, Pattern Name: Tough Dog Toys
My dog likes the bones, especially because they are peanut butter-flavored. The bones are very strong and well-made, so they are good for heavy chewers. By the way, these bones are very large for big dogs only!

They last for months
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
This is my second order of this product. I have 2 medium size dogs and they love them. The nice thing is a 3 pack of these is that they will last them for a few months.

Indestructible
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
Finally found a chew bone strong enough for our pit mix, would highly recommend for an agressive chewer! Will buy again
