I hired a trainer to help me introduce a new-to-the-family adult Lab to my Yorkies several years ago. She had me do it on neutral ground, during a walk at a park. We started with them both on leash and proceeded on a parallel path for a while. They were all behaving, so we did let them touch noses early on, then we just proceeded on a long walk. As they grew more comfortable, we let them have more interaction. Only after that did we bring everybody home.

I think that helped. There was some jostling for position in the pack in the days that followed, but I think it was lessened by that walk.

If you have a fenced park or neighbor's yard where you can introduce them off-leash after a while, that might even be better.

Good luck! Let us know how it goes.
