The main reason many people choose a Labrador dog is because it is naturally spirited, playful and respected.  Since it is a hunting dog, it is very instinctive and can act on impulse, including doing things you may find unfavorable.  To keep it in check, you have to train it to be obedient and make it understand what you expect from it.  The best way you can do this is by getting a labrador obedience program that focuses on bridging communication between the owner and the dog to create a seamless instruction channel where the dog will understand and obey the owner.
