If you assume you will always be walking your Boxer on a leash and do not need to teach him the "Heel" command, think again! Did you ever see someone being walked by their dog? You should not be behind him or her, essentially allowing them to lead the way. Your dog should be by your side, walking together in tandem.
When you walk with your Boxer, as he grows from cute little puppy
to a large and strong dog, you will want your dog to walk with you. Walks will not be pleasant if your Boxer is trying to pull you along the street. With you in control, you should be going at your
pace and taking corners or moving around obstacles in the direction that you choose.
Begin by having your dog on a short leash. Hold a treat in your hand. Say the command word, "Heel". Begin walking. Take 6 or 7 steps. If your dog walks nicely beside you, stop and give him the treat. Say words of praise that include the command word such as, "Good dog, you learned to heel".
Whenever your Boxer does not walk along side you, do not give him the treat. You must stop walking, allow the dog a moment to recoup and begin again.
As time goes on, your goal will be to be able to take more and more steps before giving the treat. Always use the command word.
If your Boxer has learned to walk with you for quite a distance, repeat the word in a pleasant tone as the 2 of you stroll down the street.
Give an occasional treat and certainly give words of praise. A dog can never receive enough positive reinforcement.
