This is also a red wolf...he's just being lazy.
Wolves ears are like cats they can go to a 180 degree angle. Fowards, sideways, backwards, and downwards (Downwards does not add to the angle)
This guys ears are the same angle as the one above.
Ears on a wolf can be many differant sizes, they are rarely skinny though. Usually, the smaller the wolf, the bigger the ears. A read wolf would have bigger ears than a grey wolf.
Emotions in ears
Ears on wolves tell emotion as well as the tail, (Again.) Same with the cat, the ears will relax if they are tired, or relaxed. (Obviously.) If the wolf is angry it's ears go back, if it's REALLY angry then they will point straight up and foward, as they glare (in a way) at what wolf they are mad at, Happy, just normal, sad could be backwards.
