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.

Winnie Loves Them!
Size: Medium (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
My Winnie is an aggressive chewer and she loves these bones. They're indestructible and they must be delicious because she works on them every day. I was a bit concerned when they were out of stock for a few months. Please don't discontinue them!
