Have researched this before. I was told by a dog behaviorist to limited the amount of space she is allowed in when she first moves in. This is teaching her boundaries and resetting her order in the pack. When she sees one dog being allowed to wonder throughout the house and she has to stay put, say inside the kitchen or bedroom or xpen area, she will quickly learn. This is not for a long duration, but for the beginning time until she is used to the new family. Also he says to introduce a new dog to the pack outdoors before letting them meet inside. But I'm sure it can still be corrected after that, the choice is always yours.
Also feeding your other dog first, treating him first, leasing him first ect.
What others said is true though, the yorkie female is one of the most domineering of any breed. However, with persistence it can be done.
Yes you should be kind and gentle, but if she is displaying behaviors that you don't want use a sharp "no!" or another sound that you would like to make that means no.
