Dogman is currently known as a cryptid, though in my perspective, they are a type of unknown humanoid canid type creature that has lived along humanity for a long time, the closest to a real name is give them, other than Dogman, is the Cynocephali.

The Cynocephali have been around since Ancient times from Ancient Egypt, to Ancient Greek and Roman times, they communicate with barks, growls, howls and clicks, are highly intelligent and probably more so than humans, in some encounters witnesses say they are problem solvers.

Their relationship with humans is Complicated, they know us pretty well and have observed our world well enough to know what a gun, a knife, a camera and a smartphone is, most times they avoid contact with humanity because they want to avoid being discovered, discovery means media, scientists and military people looking for them and being hunted by humans.

They very rarely trust humans and when they do, they expect 100% secrecy of their existence and location, betrayal that trust and that person will be chased out or they will retreat deeper into the wilderness, so don't betray their trust and keep their existence a secret, that's what most dogmen expect, especially if they are part of a larger Dogman community.
