I can't offer much help, but will give what I can. Often animal spirit guides resonate with us on an energetic level; there are similarities in our energies. Here is the little information that I have:
Red Fox - his wisdom includes shapeshifting, cleverness, observational skills, cunning, stealth,camouflage, feminine courage, invisibility, ability to observe unseen,persistence, gentleness, swiftness
Mustang Horse - power, stamina, faithfulness, endurance, freedom, control of the environment, cooperation, expanding one's own potential, friendship, travel, astral travel,warns of possible danger, guide to overcoming obstacles
Snow Leopard - understanding one's shadow side, trusting one's inner self,agility, strength,ability to stalk, understanding the power of silence
Snow Owl - stealth, secrecy, silent movement, seeing behind masks, keen sight,messenger of secrets and omens, shape-shifting, link between the worlds of dark and light,comfort with shadow self, moon magic, freedom.
Hope that is at least slightly helpful in some way.
