It grew to about 8 feet (2.4 meters) in length, 4 ft 6 in (1.4 m) at the shoulder, and weighed around 450 lb (200,000 g). They had glistening white or silvery coats of fur and eyes that were either silvery or a very pale blue, with the latter eye color being more predominant in their species.
These creatures were known to often have a foul disposition.
Using their fur as camouflage, winter wolves would lay in wait for prey. When an ambush was triggered, winter wolves would encircle their prey and take turns to attack, or attempt to pin it. They could breathe gusts of cold as well as bite their victims. They could also trip their enemies. They were immune to cold and cold magic, but were vulnerable to fire.
Winter wolves typically lived in packs of around three to five. They were well organized and their leaders were both the strongest and smartest among them. When hunting they typically traveled against the wind in order to ensure that their prey couldn't smell them.
They inhabited the region of High Ice, where they often hunted ice toads. In the Unapproachable East, winter wolves could be found in the the High Country and coastal regions of Rashemen, as well as Ashanath and Rawlinswood.
Beyond the Prime Material plane they could be found in the plane of Clangor, where they were used as mounts by the plane's goblin inhabitants, and the plane of Jotunheim where they were as large as elephants.
