Crack!, is a breakable training treat. Each package contains two tasty bars that can be broken up into as many as 50 small squares per bar (or into larger pieces if you want as well). And at only 2 calories per square, they're the perfect training treat. We care about farm animals as much as we do dogs, so we only use nitrite-free, free-range pork in our treats. Bar Size: 4.75" x 2" (contains 2 bars per pack). Available in 3 flavors: Bacon, Peanut Butter & Pumpkin.
