training your dog to walk on a leash

start with your dog standing at your left side. with several treats enclosed in your left hand, hold your left hand right in front of your dog’s nose (within 1 inch of it). say “let’s walk,” and walk in your intended direction. every few seconds, pop a small treat into your dog’s mouth and praise her for walking along at your pace. you’ll need to frequently reload your hand with treats from your left pocket or from a treat pouch attached to your waist. if she pulls ahead or to the side, immediately stop. get your dog’s attention by calling her name again. ask her to sit, and praise her when she does. then put the treat-loaded hand back in front of her nose and start walking again. go a little bit farther every day that you practice. after at least a week of daily practice with lured walking, stop luring her along with your treat-loaded hand, and instead just carry your empty left hand in a natural position at your waist with elbow bent. say “let’s walk,” and reward her, about every other step you take, with a treat that you get from your left pocket or waist treat pouch. when she can walk along without pulling for several minutes, begin gradually increasing—over many daily training sessions—the number of steps you go in between treats so that your dog is walking longer distances between rewards. reward her every other step at first, then every 5 steps, then every 10, and so on. eventually, you should be able to walk with your hand comfortably at your side, periodically (every minute or so) reaching into your pocket to grab a treat to reward your dog.
