Domestic reindeer (which, in Europe, is all of them - except for a small non-domesticated group in the southern mountains of Norway, and the Svalbard reindeer).

Domestic reindeer were domesticated by a nomadic people, or at least not an agricultural one. When that's said, they don't look "tame" like cows or sheep, but on the other hand anyone who's been involved with bringing in sheep which have spent the whole summer by themselves in the mountains will want to discuss how "tame" sheep can be..
