On Toravon in VoA, especially 25-man, you may find Frozen Orbs running amok and generally destroying faces.
If you send pet (I raid with a wolf) and hit growl, intimidation if you have it etc, the pet will hold aggro and -not- take damage due to the -90% on AoE strength. Granted, I'm BM so the pet does more damage (= more threat), but I still think pets have hidden threat mechanics especially when set to Defensive.
Try it out, but make sure you don't stop them right next to tanks/healers
