BarknBig Pig Ear chew. We all know about Pig Ears, if you didn't, now you do. These have been around since the beginning of natural treats for dogs. This is the equivalent to bacon for dogs. Forget those bacon-like formulated treats, this is the real deal. They are crunchy, which dogs love. They are tasty, which dogs love and they are good for just about any size dog. Be careful not to over-treat with the pig ear as it is a little higher in fat content than most.
