To find out which of your Animal Guides is your base totem and protector spirit is relatively easy:
Sit comfortably in a meditative state.
Take 3 deep breaths and send out the question "Which animal is my Base Totem and protector spirit?
Sit quietly and breath gently until you sense which animal it is. Do not doubt, it will be the first one you see or sense.
Ask it its name and ask it to protect the door between you and the Spirit world, leaving you protected 24/7.
