Dogs have an amazing capacity to learn commands.
Most pet dogs are taught with vocal commands, but hand signals or nonvocal sounds are also effective. Whatever method you choose, most dogs only need to know 11 simple commands to get along happily with you and the rest of the world. Some dogs have a way of pushing their way to the front of the line when they want to go through doors or down narrow hallways. This is one of the easiest commands to teach, and also one of the most useful. Dogs who know how to sit are less likely to be jumping on you or anyone else, fighting with other dogs, or dragging you across the street at a red light.
