How do you train a German shephard?

first of all NEVER train anything with treats because when you are away from home or wherever you wont be able to give him/her treats and when you dont they will be confused and it will just go downhill from there. anyway start with something simple like sit, lie down , or shake then work your way up. but when your GSD-German Shepherd Dog- does it right simply say one or all of the following- good dog, good boy, good girl, good_____-what ever your GSDs name is-, or even yay you did it! dont forget to pet your dog when you say those things. ITS A SIMPLE PROCEDURE CALLED PRAISING!!!!!!!!!!!!!!!!!!!
