Take down Loskey first. Pop blood fury and start with L.bolt, then hit chain lightning, and finish with an earth shock. He should be dead or below 10%. Finish the dogs off with windfurys and crossheal yourself with lesser HW's.

Things that can help if you still have trouble: healing stream x5, stoneclaw x5 for the dogs if you do double lightning bolts instead of chain lightning on Loskey, and fire nova totem bombs.
