Weird to humans, amazing to dogs!
Size: Large (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
I find these expensive and weird, and yet I'm not the one chewing them and both of my dogs disagree. They feel they are amazing and tasty! They love to chew on these, and chew, and chew. Who am I to argue?

Defective cracked
Size: Large (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
The stuff inside was cracked. It took my dog a few minutes to get it out. I bought these from other stores in person and didn't have any problem. It must be from shipping and handling.

Great Product!
Size: Medium, Color: green, orange, pink, Pattern Name: clean tuff bone bacon
My dogs love their dental chews! This product is durable and the perfect size for each of my dogs. I've purchased two of them (medium and large). One of my dogs is an aggressive chewer and this product is holding up. Hartz makes great pet products. I'm very happy with the product.
