Great chew toy for large, tough chewers
Size: 1 Count (Pack of 1)
My dog is a heavy, strong chewer over 100 lbs who will chew this for an hour. It lasts, keeps him occupied and the smell isn’t terrible. Love the large size for a larger dog. Great buy.

Awesome bone for all dogs!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
My dogs LOVE this pig ear! It is very lightweight and easy for any dog, from my Great Dane to my Maltipoo, to carry and chew on. It has no odor, yet the dogs were interested immediately after smelling it. The pig ear is perfect for every dog in our household and keeps them busy for hours. Since it is curved, it is easy for them to hold on to and to pick up. We have had this bone for a few weeks, and it has lasted through our little dogs, fosters, and Great Dane! The bone is very durable, and based on the previous bones we’ve gotten from Pet Qwerks, I’m guessing it’s going to last quite a while! I recommend this to anyone wanting a long-lasting bone for their pups, especially those tough chewers!

Large and durable!
Size: 1 Count (Pack of 1)
It's large but my pitties love it. I bought this to replace a small one I found at a local store about a year ago and this one is better! Large and durable and a favorite with my boys!

Chewer was indifferent
Size: 1 Count (Pack of 1)
At first, the two ears I bought were mainly ignored. Now I am seeing teething marks. Took about 2 months for my chewer to stop chewing my wood fence and on these.
