Extreme chewer
Size: 1 Count (Pack of 6)
The dog loves them. Not the freshest smelling thing, but she gets through them so quickly it doesn’t really matter. She is an extreme chewer. They’re a good size. I think the price is fine. She weighs about 12 pounds. I know this is a lot of random information, but it can help you make a decision on whether to purchase or not. I would recommend them.
