Yup its true though, if you have control over him than he can't get away.

Grab the other end of a leash, tell him come if he does not listen reel him in. If you tell him to come multiple times he will wait until you say it multiple times before he listens.
Praise when he comes.

Its good to always have treats in your pocket when you are training, you can practice this anytime, if you call him in the house you have a reward for him.
Oh and NEVER EVER punish a dog when you call him to come otherwise he associaated the come word with scolding. He has to want to come to you, there fore you have to be better, funner than what ever it is he is doing, he has to love you lots.

Good luck
oh & obedience will help w/ that command too
