These cow hooves are a fantastic alternative to cow ears as they are a lot tougher to chew, keeping your dog entertained for longer. Great for teething puppies (saves the furniture) and aggressive chewers. Cow hooves are highly nutritious, an excellent source of natural vitamins and minerals and grain and gluten free. They are also great for promoting dental health as the chewing action scrapes plaque and tartar off teeth. As an added bonus place soft food, peanut butter or cream cheese in the hoof to keep your dog engaged and entertained for longer.
