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).

Great product
Size: 1 Count (Pack of 10)
My dog loves these pigs ears, she's a 20 lb Shih Tzu Jack Russell mix, I cut the ears in half but they're still going within 10 minutes.

Not the same as the last shipment

I have always thought these were great but this time they were black. Didn't look fresh. Don't know if I will buy again.
