One clue is in mythology.

Across many cultures, dogs exist in a transitory space between life and death (ie Cerebus). Hinting at dogs being "transitory" from here (camp) and out there (the wilderness). Going between, getting scraps, staying for a while, leaving. You can imagine a process unfolding over Millenia of gradual domestication this way. You see it in Ancient North Eurasians myth across different cultures. Ancient North Eurasians are genetic precursors Eurasian, Western Europe, and American lineages where dog domestication originated, and arguably where many cultures have the deeper associations with dogs.
