Check if pet gets feared

[Fierce]

So, sometimes when my pet gets feared in a boss fight i fail to notice this cause i‘m too busy with everything else thats going on.

Now when the fear effect is over my pet resets and returns to my side. And sometimes i dont even see that. So now hes just sitting there, doing nothing for a good amount of time.

I wanna write an addon that checks whenever my pet gets feared. I dont know how tho. Now there are a whole lot of debuffs that cause a fear effect. Anyone got an idea where to start? I found an event called PLAYER_CONTROL_LOST but it doesnt work on pets.
