Will Aela the Huntress ever use werewolf form in combat?

I completed the game, and in all my time playing, and having her follow me, I have never seen her wolf out.

So, I guess not.

Normally, as said above, there is no way for her to turn werewolf...

But, if you are a PC player and don't mind a mod,

Enhanced follower Aela mod.

This may help, making her able to transform into werewolf and also the mod has some other helpful additions as well.
