If you want to push your dog away from you, move towards them, if you want them to come closer, move away. If your dog is out and running loose, instead of calling their name and moving toward them, get their attention and run in the opposite direction. Dogs love to chase and their instinct to chase usually kicks in and they will chase you right back into the house. And when my dogs chase me (as long as they don't nip my heels) and catch up to me they get a huge reward - no matter what their reason for running away was - I want them to know that coming to me is the best thing in the whole world.
