This 14" to 16" femur bone is uncut, cleaned and lightly smoked. It is an ideal treat for large breeds and makes an impressive gift item. 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, to occupy a dog during travel time, or to help alleviate separation anxiety. They provide an enjoyable chewing experience and satisfy a dog"s natural carnivorous instincts.
