My go to happy thought is this:

Wild dogs, wolves, coyotes, etc… don’t have eyebrows. That is to say that they never evolved the muscles necessary to move their eyebrows in an expressive way.

Moveable eyebrows were a trait that domesticated dogs specifically evolved in order to mimic their humans and invoke more empathy (and let’s face it…likely manipulate us for more treats)
