We emphasize focusing on the positive in clicker training — not pointing out a mistake, but determining a concrete, alternate behavior instead. In dog manners training, this often appears as replacing “don’t jump” with “sit to greet.”
But really, what’s the harm in pointing out a mistake? Sometimes we have to know what’s wrong so we know to avoid it, right? And surely we humans are smart enough to think through the big picture?
Eh, not so much.
