There will most likely be an adjustment period, check out my latest thread....

Many people do have yorkies who get along right away, many don't. But I say if it will benefit in the long run....go for it, that's why I did it, I know in time all will be well, just gotta get through the tough, rough 1st month or 2. I enjoy it by spending QT with each pup. For some reason although my pup Reesie is STUNNING (what pup isn't??? right) but Snickers (my 2.5yr old) is just beyond words beautiful to me. I see things in his that I love that I have never noticed before. BUT I CANNOT WAIT UNTIL THEY ARE FRIENDS!!!!
Good luck-
