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.

Great Chew & Flavor
Size: 1 Count (Pack of 6)
My dogs chow down on these great crunchy/crispy snacks. Great for light to medium chewers. My intense chewer loves the flavor...but he can get through one ear in less than 20 minutes (on a relaxed day).
