There are no such characters named "Louis" on Family Guy so your question cannot be answered.
Once.
He's never appeared on an episode of Family Guy. He did however appear in commercials w/ Stewie during Peter's Progress
This happens in many episodes. It is just Stewie trying to annoy Brian. Throughout Season 7 it happens more.
Stewie told Brian he had killed Seven babies.

Sounds like you're referring to the sensational episode 'Road to the Multiverse', in which Brian and Stewie visit one of many universes where humans are pets and dogs are owners. They visit the Griffins and obviously Peter, Lois, Stewie, Meg and Chris are dogs and Brian is a human.
He has four. Chris, Megan, Stewie and Bertram (deceased).
