Basic strategy is to simply have one tank at the front of the beast and everyone else behind. About the only AE worth dispelling is the 200FR debuff as that can greatly increase the damage taken from his fire AE. This mob goes down very fast and we don't bother with them too much anymore since they don't respawn once Magmadar is dead. You should have another tank (with FR) ready to tank the dog. Since some of its abilities (like the fear and stun) cause the tank to temporarily lose aggro, it might wander into the clothies area, and bake them.
