Chasing a dog that is running away is almost a sure way of letting him take off. A chased dog will just keep running because they think you are playing with them a game of "keep away". Or perhaps, they think they are in trouble.
The more you move in their direction, the more they'll move away. And if you try to reach out for their collar, they'll swerve away. Some dogs may even snap or bite.
What works better is to run away from the dog if you can catch their attention doing something that intrigues him. Start kicking the dirt with your feet enticing them to join you in digging, start singing in a silly voice, start making movements with your hands, and then start running.
Your dog will likely approach to see what you are doing and he may chase you all the way you need him to be.
