As far as I know, they spawn on every difficulty except peaceful. They are very rare, so you will have to search a while. But you should look at light grass areas. They can only spawn at light level 7 or higher, on grass, typically in taiga and forest biomes more commonly during dawn and dusk periods of the day. However, they can move around all over the map, so they can technically be everywhere.
Wolfs are mostly found in forests and biome areas. Your difficulty can be on anything from what I heard.
The only information online about a "White Wolf Team" is in relation to Minecraft. Minecraft is a popular online role playing game. If a person would like more information about the White Wolf Team in Minecraft, they may do so by visiting the Minecraft website.
There isn't one. Wolves are already in Minecraft. There are other tools and mods that can help you find and tame one though.

The only way you can disown a wolf is to kill it.
First make sure your minecraft is updated to 1.4. Wolves spawn commonly in two biomes but rarely in others. Woods and Taiga. Taiga is snow covered land. If you find a wolf, tame it and look around because they usually spawn in groups. If you do find a wolf then make a landmark so you know where you found it and you can return to that spot again because it is likely they will spawn in the same spot again.
