Dogs like kids compete

Dogs, like children. once having learned a skill, like nothing better than to show-off their competence as soon as possible. They'll compete for your approval and vie to be the very best they can. In psycho-babble, its called the "model-rival" method. First a superior shows you how,or what it is, that's wanted, then you compete with your peers to excel and be taken notice of by the superior who taught you.
