Wolfos

First appearing in The Legend of Zelda: Ocarina of Time, the Wolfoses are anthropomorphic wolves that attack Link with their claws and sometimes somersault backwards when attacked. One appeared as somewhat of a mini-boss in the Lost Woods, and Link could also meet them in the Forest Temple. Striking a Wolfos's tail will kill it in one hit. In The Legend of Zelda: Majora's Mask, they appeared in place of White Wolfoses in Snowhead Mountain, once the boss of the Snowhead Temple was defeated and spring returned to the mountains. One Wolfos also appeared in Sakon's Hideout in Ikana Canyon, which would be fought during the Couple's Mask Quest. They also appear in the Southern Swamp at night.

White Wolfos
Completely white, cold-habituated counter-part of the Wolfos. They resemble Arctic Wolves. They are far larger than standard Wolfoses, but identical in strength. In Ocarina of Time, they appear only in the Ice Cavern and the Gerudo Training Ground and they are limited (Though in Master Quest there are many more in the Ice Cavern.) In Majora's Mask, they are the same size as a regular Wolfoses. A hit to the tail will also end in a one hit kill. These Wolfoses are also in Twilight Princess, with the ability to burrow into the snow (although they have lost the ability to defend themselves with their claws), and are notoriously (for them) glitchy, which is a blessing for players, as this allows an easier kill. They are commonly found in snowy areas.
