How to introduce pets to one another?

My boyfreind and I are moving in together and we have three pets. I have two older cats and he has an older dog. I am concerned about introducing them to one another so that they get along. My cats have never lived with a dog and his dog is interested in cats to chase. One of my cats has FIV and I am concerned about the stress it will cause to him. Any tips or advice?|||Introduce them slowly. Leave the cats in a bedroom for a few days, especially if you are moving in to a place that is new to the cats.|||Get dog trained not to touch cats. Nothing else will work.
