The wolf is a predatory canine beast, whose medieval reputation was one of rapacity and strength.  It was a common charge in medieval armory, called a “leu” or “loup” in early blazons, and found as early as c.1275 in the canting arms of Lou [ANA2 109].  The wolf does not seem to have a default posture; the illustration shows a wolf rampant.

A “wolf ululant” has its head raised, howling or baying.  The term is unique to Society heraldry, and as a purely artistic detail worth no difference, is no longer used in blazon.  For related charges, see dog, fox, hyena, werewolf.
