Dogs came from a combination of selective forces...

The first, in the natural population of wolves... is about variation in the genetics controlling the level of trust versus aggression... and how function interacts with other factors, like learning, that enable them in overcoming that natural tendency to resort to aggression... where there is a free meal available only if they will risk getting close enough to take it... and respond to that reward, with success, by becoming less aggressive over time...

Humans are wildly successful as hunters... usually have bones with meat on them left over, and with plenty enough to not miss it if they share... find the sharing entertaining,.so don't mind throwing a dog a bone... Over thousands of years... wolves creeping around in the shadows outside the campfire seeking to scavenge a free meal... slowly became dogs sleeping beside the fireplace waiting to be fed... through selection, both natural and artificial.

The genetics of that are pretty well worked out...

Dogs... evolved from wolves that had a short circuit or two occur in their maturation process...

Those genes control "cuteness"... and they control the puppy like behavior in younger animals... which normal wolves grow out of as they mature from "teens" to adults... to provide them with Darwinian survival skills they require in the wild...

Dog breeders have maps of those functions... can tell you where along the continuum (and which genes are tied to) this breed or that, and where each breed falls... and what the characteristics are with this or that genetic variation...

Dogs have their maturation processes truncated... to stay more like puppies... where their survival depends on them being trusting, cute and friendly enough to win free food from humans... while some are selected for remaining friendly... but still aggressive enough to scare away the occasional burglar... ?

And, of course, once that basic conversion in domestication occurred... dogs willingness to be malleable for a meal... met with our willingness to exploit that in controlling their sex lives... and so now we have Toy Poodles and St. Bernards...
