Our NEW Joyful Jerky for dogs start with cage-free chicken breasts or ranch-raised beef rounds, which are thinly sliced, and then air-dried to savory perfection. They're a delicious way to show your dogs how much you love them during snack time, or anytime really. Jerky Filets are larger pieces of jerky that are a deliciously chewy treat for medium to large dogs, but are easy to break into smaller pieces for dogs on the more petite side.
