These are the extremities of the mammoth bones that are removed, cleaned and lightly smoked. These bones are ideal for satisfying large dogs chewing needs. Hard bones are a natural way to clean teeth and exercise muscles. They improve the dog's dental health by giving the dog a chance to exercise gums and scrape teeth. Natural bones can be fed anytime as a snack or reward, as a substitute for chewing furniture (especially useful for teething puppies!), to occupy a dog during travel time or to help alleviate separation anxiety. They provide an enjoyable chewing experience and satisfy a dogs natural carnivorous instincts.
