Before you train your dog to heel, it's important to understand exactly what heeling is. Heeling is precise. It is not casual. Teaching your dog to walk politely on the leash is not the same as a heel.
Competitive heeling will vary depending on the country and type of trial. You will see dogs heel with their head wrapped around the handlers' left leg in some sports, while others do not allow the dog to touch or crowd the handler.
Typically, heeling refers to having the dog on your left side with his head and shoulder aligned with your left leg and hip. The dog remains in that position through pace changes and turns. When you stop, the dog sits perfectly straight
Before training your dog to heel, decide what heel position means to you!
