You have the right idea. You may also want to try making your own twisted leaders - i don't trust many things that are straight from the packet.
Making my own, i attach a swivel before ending the twisted leader. This allows me to attach a split ring - making changing lures and the connection itself a breeze.
I haven't seen a knotted dog so i can't comment on how to connect it. I have heard of anglers crimping a single stand to the twisty then using a 4-turn Uni knot to the lure.
