What are some real-life 'Snow Wolves'? 🐺❄️

Nack is set as a 'Snow Wolf', but in reality, there isn't a species officially called 'Snow Wolf'~ However, there are quite a few wolves that actually live in the Arctic, tundra, and cold high-latitude regions! 🐺 Arctic Wolf One of the subspecies of the Gray Wolf, living in places like the Canadian Arctic Archipelago. Their fur is mostly white or off-white, probably the closest to everyone's image of a 'Snow Wolf' 🤍 🐺 Northwestern Wolf Mainly distributed in Western Canada, Alaska, etc., these are quite large Gray Wolves. Their fur color varies greatly, with white, gray, and black all appearing. 🐺 Eurasian Wolf Their distribution range is very wide, extending from Europe all the way to Russia, with some populations living in cold regions like Siberia. Additionally, there are many Gray Wolf populations living in northern tundra, forest, and snowy environments ❄️ So, the 'Snow Wolf' in reality isn't a single species, but more like an imagination of wolves living in cold, snowy areas~ As for the coolest wolf with blue markings and red eyes... So far, I've only found Nack 🐺 😆
