Animals vs non-Animals

[EvilMinion]

OK, so according to the Handle Animal skill and training of animals, normally they will only attack humanoids, monstrous humanoids, giants, or other animals (extra attack tricks aside)

Most folks know about this, and apply it when they're using animal companions and the like...

But I had never actually thought about this from the other direction. Given that PC's can fall outside of those 3 types quite often (with the influx of races like aasimars, fetchlings, oreads, et al)
I'm pretty sure most wild animals are not considered 'trained', so how are they supposed to react?

Does this mean an aasimar, thiefling, oread, et al character will not be attacked by animal enemies?

I don't think I've ever seen a GM take this into account. Should they? Has anyone ever actually cut both ways with this knife?

I just use the "If it looks like a duck ..." rule. I always assumed that "humanoid was in the description for aasimars, etc. (outsider, native, humanoid, etc). but even if it isn't I would have no problem with animals attacking them. I think the above rule was to acknowledge that animals don't like to approach hideously unnatural things like aberrations and things from beyond. Horses might not love being ridden by a tiefling, but a trained war dog or hungry bear will still attack one.
