Found a great natural dog treat to make, and yes you can call it "chicken crack"! Works best if you have a food dehydrator. Semi-freeze boneless chicken breasts, take out one piece at a time to cut. Cut with the grain, as thin as possible. Place pieces flat on dehydrator trays. Set on meat/high and dry for 8 hrs. Place in ziplock freezer bag and freeze. Take out what is needed for the day. Your dog will love it!!! Haven't given it to the cat yet, he might like it too.
