When heeling, your dog always works to keep pace with you, only stopping when you stop or walking when you walk. It also means your dog must ignore all other distractions to mimic your movement.

Healing can be tiring for your dog due to the constant focus required. Therefore, you should train this behavior in a low-distraction area, such as a quiet room or hallway inside your house.

• Say "heel" and point to the side of you on which you want it to walk.
• As soon as your dog comes beside you, click or mark, and then give them their reward.
• Walk with your dog, continuing to mark and give them a reward every few steps if they stay beside you.
• Repeat this process a few times.

After they are comfortable with this, stop pointing to your side, and allow your dog to willingly come up beside you.
Once your dog has begun to master this, you will need to increase your pace, turn, or zig-zag while you walk. Essentially, you want to try to "lose" your dog, so that they know to work to find the proper position again. After they have mastered all of this, you can begin to add in distractions, such as by asking them to heel in a busy park.
