Welcome to Yorkie Talk and congratulations on the new addition to your family. Be patient and continue as you are doing, petting your other dogs, acting confident and cheerful. The dogs will work everything out in time.
You can encourage togetherness with playtime, or trick training with treats, or walks together. That is how my guys came together.
Give her time and don't worry. She will settle in.
