Rhodesian Ridgeback and a Pomeranian or Chihuahua?

Is it possible to have a Ridgeback with another small dog in the house? My wife and I might be moving to a rural area and I'd really like to get a Ridgeback. But my wife really wants a Pom or a Chihuahua and I've read that Ridgebacks have such a strong prey drive that they'll chase and kill pretty much any small animal. Can Ridgebacks be friends with small dogs, or will it always treat the tiny floof like a chew toy?
