Great quality and flavor
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
I have two dogs that can chew through everything within a day. Not these, going on four days now, there are signs of wear and tear but still intact. The dogs love the flavor.

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.
