The word puppy comes from the French word papee, which means doll. And a doll is how we treat it. We handle it, hug it, stroke it, brush it, play with it. To lie on your back and be assaulted by a litter of puppies, simultaneously climbing, clawing, wagging, and licking, is an experience unlike any other. It is good that a puppy is cute, as it prevents most owners from killing it when it does the inevitable damage to house, property, and self.
Puppies do harm primarily by biting, clawing, and excreting.

Traumatized dogs recycle their bad feelings later. Which is why people are leery of adopting previously owned dogs. There were difficulties with the dog.
