Our Original Recipe was formulated to excite dogs with the robust flavor, superior crunch, and perfect bite size that keeps them craving more. Our treats can be used for rewarding good behavior, during training, or a take-along for your dog during walks. They are non-greasy making them perfect for placing in your pocket. The shelf life is one year, however, we have never heard of a bag being on the shelf that long. Once your dog gets a taste- the bag is not likely to be on the shelf for more than a few days!
