How do you teach animals new tricks? With positive rewards only. You ignore bad behavior.

And you end up with a fat spoiled brat ... I mean dog.

If you really take a look at the animal kingdom, you'll find out that the animals use both positive and negative feedback to teach their offspring "new tricks". There's not just "here, that's what you do", but rather also "no! This is not how you should behave." But the animals did not read didactic texts from acclaimed professors with no actual students, child-less well-meaning feminists or mothers neglecting their spoiled brats 'cause they have no time for the kids due to all the conferences and books.
