Teach a cue. Introduce your puppy to a sound cue that means, “food is coming.” Some people like to click and treat, some people use a word like “yes,” and some people cluck their tongue. Whichever you use, the method is the same: In a quiet, distraction-free area, with the puppy on a leash and collar, make the sound. The second your puppy turns toward you and/or looks at you, reward him with a treat. After a few repetitions, you’ll notice your puppy not only looking at you, but also coming over to you for the treat.
Leash walking outside may be more frustrating because there are numerous distractions for you to compete with for your puppy’s attention. Understand, from his point of view, how much more difficult this task has now become, and whatever you do, don’t lose your patience; don’t drag him or allow him to drag you! Walk slowly and click and treat if he stays at your side. If he begins to pull, stop or change your direction, then click and treat when he reaches your side again!
I mean, have you ever seen anyone successfully loose leash walk their dog using a retractable leash? I observed a man yesterday at our local pet food center trying to control his medium sized dog while another customer was walking their very petite pups. Guess what he was using? A retractable leash, that malfunctioned, the dog was able to get far enough away from the owner that he lost control and the dog went right after those little puppies. Luckily, the dog just wanted to say hello, and those two little pooches knew exactly how to take care of themselves! This scenario could have turned out pretty bad.
