By Wings, we mean Scapula. Scapula comes off the animal's shoulder blade made of cartilage resembling a wing. We deliberately remove the piece of bone attached to the cartilage due to the danger of splintering it presents in the wrong mouth. With the bone removed, this is 100% digestible.
We have also found Scapula to be full of naturally occurring hyaluronic acid to build glucosamine, aiding in hip and joint health. These Mini Wings are cut to a size that gives smaller pups the ability to indulge, but not over indulge.
If you have not given Scapula to your dog before, you can expect it to last longer than a Pig Ear only with more nutritive value.
