Cow Ears are a single-ingredient chew and a classic favorite of dogs everywhere because of their flavor and taste. Because Best Bully Sticks doesn't treat their cow ears with preservatives, chemicals or additives, dog parents can rest assured their pups are getting a healthy and safe dog chew. We don't add flavoring or smoking agents to our cow ears, either! Sourced from free-range, grass-fed Brazilian beef, cow ears are a great alternative to rawhide or supplement to pig ears as they are low in fat! Unlike rawhide, cow ears are fully digestible dog treats. These will last just as long as a pig ear. Treating your dog to cow ear chews are also a great way to clean your canine's canines! When your dog chews a cow ear, tartar and plaque are removed from your dog's teeth, leaving a healthy mouth and a happy dog.
