The UK black dog and other similar cryptids from around the world are reported to have long slender legs, especially at the rear, with a long shaggy mane. This fits with the "trousers pulled down" imv and would perhaps indicate extra fur around the feet to insulate against the snow on the ground.

http://www.monstropedia.org/index.php?title=Bergman%27s_BearIt is artwork created specifically for a fantasy roleplaying game, I don't even think the person is human, and can't really be used to suggest it is an artist representation of anything real. Kodiak bears can have hind paws of 18", so the Bergman's Bear may be larger than other Kamchatka brown bears, but smaller than Kodiak bears, certainly not twice the height of a person at the shoulder.
