i taught my dog sit, (lay)down, up, off, kiss, stay, go get your...(bone, bear, leash, toy), stop, go get my purse! still working on heel but knows "go on" for releasing from a heel. my dog is 6 months old and practice will make better but he definitely knows what they all mean whether or not he decides to do them right away. i have had ALOT of experience with animals...BUT, i am only 19. and i believe spending the time everyday 10 minutes at a time so the dog WANTS to learn the trick is all it takes.
