From Nookipedia, the Animal Crossing wiki
Fang (シベリア, Siberia) is a cranky, wolf villager in the Animal Crossing series. He did not appear in Animal Crossing: Wild World, but reappeared in Animal Crossing: City Folk. His name comes from the fang, a tooth found in carnivores.
Fang is a light gray wolf with a white muzzle, cream tipped paws, and purple eyelids (brown in Animal Crossing). His initial shirt will be an Ice shirt. His appearance in Animal Crossing: City Folk differs from that of his Animal Crossing appearance, the main change being his eyelids.
Below is a brief description of the cranky personality. For more information, click here.
Fang has a cranky personality, meaning that he can be quite rude to the player and be all around grumpy. He will warm up to the player as time goes on, and may eventually become a close friend.
Fang's house has a loose Asian theme. He incorporates an Exotic bed, exotic chest, glass-top table, a few gyroids, and a Weeping Fig and Dracaena from the House Plant set. He has the Shoji Screen (wall) and Red Tile (floor). "K.K. Calypso" plays on his hi-fi Stereo.

 Card description
Fang likes the winter most, because he can blend in with the snow and sneak up on people. And if he doesn't feel like talking, he can curl up in the snow and practically disappear. There's "snow"-body quite like Fang!
 e-Reader letter
"There's one place you won't catch me: the islands. It's way too hot for me. Cha-chomp. The last time I was there, I got a major sunburn! People mistook me for Freya. I steer clear of the heat and prefer to practice bobsledding when it's snowing."
