One of the increasingly accepted theories is that we didn't domesticate dogs, they domesticated themselves. They started following humans around to scavenge their leftovers and the braver wolves would stick around longer until they eventually lost fear of each other and basically lived together and started hunting together. Each generation breeding "love" for thousands of years before intentional breeding for specific traits really even started.
Read one paper where they can identify a gene that creates the difference between those that want to be friendly and an aggression gene.
So the domesticated ones pass on the gene to befriend humans/other animals.
And the more the dog's DNA matches a wolf, the less he's likely to pander for human attention.
