I agree with tatsxxx11 and carrie. I help teach puppy classes and although we do teach all the commands we are really teaching the "parents" how to get the puppies to do the commands at home, where there is way less distraction. We teach at least one method, since not all puppies are the same. We do not expect the puppies to be perfect by any stretch of the imagination, they are just puppies, after all. As long as they get the sit, come, and stay ( 5 to 10 seconds max.),and they don't pull your arm out when walking, that's OK for now. If they get the down that's great! As the puppies are socializing, we are just introducing them to the hand signals and voice commands, so that when it gets more serious in basic obedience, it won't be totally new to them. Asking a 4 month old puppy to do any more than that is like asking a 6 month old to recite the alphabet.
