ELI5 Why do dogs love humans?

I mean, just look at all the youtube videos.

There are two reasons for this. First is that we have breed this behavior into the dogs. Back when we first started with wolves, we would keep and breed dogs that were docile and chase off those who weren't. Over time, this docile behavior became standard. Of course there are still outlying dogs who are very mean.

The second reason is pack behavior. Dogs consider humans, especially their owners as part of their packs. The human owner is typically the alpha male and deserving of praise. That is another reason while dogs are sometimes very mean toward outsiders. They aren't part of the pack.
