My understanding is that wolves don’t have “eyebrows” at all. The fact that many dogs have them is either an evolved or selected trait specifically to communicate with humans.
I think one theory is that they were sort of accidentally selected for because they made dogs appear more friendly or attentive, making them seem like a better fit for companionship.
