Training strengthens the bond between a dog and his owner. It builds communication, understanding, mutual respect, and subtly but effectively demonstrates that you're the leader of the pack (commonly referred to as the "Alpha")—social hierarchy. If your dog doesn't respect you as his leader, you may both be in big trouble, particularly if he's a bit rowdy or dominant by nature.

When your dog obeys the simple request of 'come’ and ‘sit,' he is showing compliance to you. It is NOT necessary to establish yourself as top dog or leader of the pack by using extreme measures such as the so-called alpha rollover. You CAN teach your dog his subordinate role (to defer to you) by training obedience, manners, and/or tricks.
