These are fun Bait/Treat Bags, you can hang them up while your working with your dog, or just hang it off your wrist or belt and always have your treats at the ready. They are super fun if you want to use them to teach your dog to tug. You choose the handle length, longer lengths are great for little dogs. If you are going to use it to teach your dog to tug we recommend the longer handle lengths as the longer handle reduces shock to your dogs neck, your shoulder and saves your hands. Opening is 5" wide with a quick pull tab open for quick access to treats.
