If this is occurs only due to external powers, like magic cast by some wizard or the gods extending their powers onto some character, use some other tag (unless it is a permanent state change and the character functions as if it was a therianthrope from there on out by its own).
This is specifically limited to animals, so no transforming to dragons or half-dragons or similar.
