I am putting this together primarily for my own use, but I will also list active real-breed registries even if I don't personally use them, in case anyone else has use of a list like this. Please let me know if you know of other active* real-breed registries on deviantArt- so many groups out there are dead these days, we need to find the current ones! (Note- these are categorized according to my own ease of use, therefore multi-breed registries will list the main breed I would use them for, but I'll include a note of other accepted breeds as well).
