From our article Introducing Your Dog to Working in Harness
Many owners while training their puppy to walk to heel also train the puppy to "pull" in harness. So basically when the puppy is wearing the harness, let them pull on the lead all they want without correction. This should help the puppy associate "pull" whilst wearing the harness.
Some people start to teach their dogs the commands "gee" (right) and "haw" (left) as they turn. Another useful command to learn at this stage is "on by" which encourages dogs to continue on without distraction. It is important for your puppy to learn that when they are wearing their harness, they must stay focused - it is not a time to play. Obviously, ensure that you only spend a few moments teaching a young puppy; there needs to be plenty of fun time to socialize and sniff too.
