New dog/Old cats. Help.

Restrain the dog on a very short lease on one end of the couch. You sit with a cat on the other end. When dog lunges, reprimand and say, and growl at, because your are protecting a family member and a growl indicates such. As dog settles down, slowly sidle over closer and closer, saying good dog and good kitty, etc, petting the kitty to remain calm at all times.

This will take many rounds, but worked in a fashion (outdoors not on the couch) with my german shepherd pup who killed a hen and then became the protector of the rest of the flock within two weeks of this adoption technique.
