Training Technique - The Umbilical
Establishes Pack Order and helps the dog realize you are Pack Leader

A technique call the umbilical makes problem dogs, good dogs and makes good dogs better. Put him/her on leash and hook the leash around your waist and make him/her walk behind you as you do your every day chores (do the dishes, vacuum, etc) do this indoors and in you backyard as well. As you do this never let him/her go in front of you, never let him/her enter a doorway in front of you, never let him/her go up the stairs a head of you. (The pack leader always goes first. When you first do this watch to see if he/she tries to take the lead. If he/she does you will know he/she thinks he/she is the boss.)

Don't talk to the dog too much.
Every member of the family should take turns doing this as well as feeding him/her.
