I think it's dogs adapting to us especially if you obtain the dog as a puppy. Dogs look to us for guidance on how to react to diferent situations and such and mimic our behaviour because they think we're right since we're Alpha in their eyes (poor sods eh? LOL). Like I'm a social-butterfly, i LOVE being with people, I'm hyper, a little crazy...ok a lot crazy, always looking on the bright side of things, enjoy making people laugh or at least smile, I'm the one that when I walk in the room the whole place brightens up and i'm constantly smiling and in a good mood, consequently OC's the same way. We are total identicals in personality
