Our supplier says: “The cow ear is baked to a soft, chewy texture. This chew isn’t as hard as a bully stick, so we recommend these for senior dogs or dogs with missing teeth. We also recommend this easily digestible chew for dogs of all life stages, especially puppies! These ears have almost no odor and are a very clean, non-greasy chew if you are worries about a mess in your home or on your carpet. There will be a slight variation in each ear.”
