Nature's Own Pet Chews’ Cow Ear Treats are an all natural and healthy pet treat. Slow baking created a treat that’s high in protein and low in fat, unlike greasy pig ears. These treats are great for big and small dogs who obtain enjoyment from chewing. The treats are baked and packaged in Michigan facilities. Doing things the right way, takes a little more time, but we think your pet’s worth it! Hormone and pesticide free, with no added antibiotics.
