Passive Submission~ Submissive wolf is laying on back, often with tail tucked between legs, curls up front paws and lays ears back against the head. Wolves do this to show submission without going to the full blown out active submission. Mostly done by lower ranking wolves to all members of the pack that are higher in rank.

Fighting Pin-Down~ Display of dominance. An alpha pack member will often assert his or her authority over other pack members by this form of ritualized aggression. Dominant members of the pack will pin down the lower ranking ones to make sure they understand they are lower in rank.
