Jack's Premium bones and other chews are slow-smoked over a wood-fire. We source all of our bones from local Texas slaughters and do not add any preservatives. Jack's Premium 'baby' bones are bones that happen to be smaller than the average dog bone. These are a great option for small dogs that still love to chew and enjoy a treat. Our bones are not limited to just babies, we offer large bones for your medium-large dogs as well.
