I have 3 and my littlest one is the boss around here. Coco my oldest is a male and he is sooo submissive. He really is a great little guy. Trixie my youngest is a big girlie, about 10-11 pounds and My little Pebbles (4lbs) just runs the show around here. They all get along well. I was nervous when they play because Trix is so much bigger than Peb, but Peb is right in there defending herself. Coco walks away with a look like, "uhhh girls" rollie eyes. Haha He doesn't want to get involved. Mine are all still young though and they have been together for a while so maybe that's why they get along so well. I don't know about having an older dog and then a younger one, what will happen.
