Dogs are incredibly good at perceiving through their nose. They smell almost everything around them including other species’ old feces. Some dogs even eat their own. A lot of smells must be something unbearable with human nose but they take them well. If their physical mechanism enables them to embrace all kinds of disgusting smells with less rejection, I think the same mechanism also makes the nature of dogs more tolerant and altruistic than that of human being who are easily disgusted. Dogs are overall just nice : )

Dogs were domesticated in such a way so that their very existence depends on them being nice to humans.
