Personally have trained my dog to travel with me to South America with no leash. Trained him to walk with me along the sidewalk and have him know exactly who his owner is and not run away or be easily startled. I Develop a unique language to communicate with dogs. This helps with the ability to train them to listen and follow clear instructions when out in public. I aid in calming dogs down as well as helping them release their energy if they are too energetic.
