Nelson is a Suburban K9 trainer who excels at training dogs to listen off leash. He not only trains dogs to come when called, but also teaches dogs to heel without a leash. There is nothing more fun than taking your dog to the park and being able to trust them off leash. Dogs love to run and play and a well trained dog can have much more freedom.
Notice that Nelson makes sure to keep the dog guessing. Sometimes he tells the dog to come in front of him and sometimes he calls the dog to his heel side. At one point he even turns his back and asks the dog to run around him to sit in front. A busy dog is a happy dog and advanced obedience definitely keeps dogs busy!
