I know a tamer who does these with a well trained cu sidhe, but he's generally good at what he does.
He puts the dog on it and then just flamestrikes the heck out of the coil, basically mana dumps on it, and at the end of the process the dog is pretty hurt but the coil is dead. He's a stacked 120 eval tamer mage template with a good suit.
If I recall correctly, a good superdragon did okay when I used one, my tamer has chiv and can pull the mortal off now and then.
