It really just depends on the dog. Some transition like it is nothing and others do not want to go outside when they have been going inside. I have never trained a Yorkie myself, but lots of other dogs. Terriers, poodles, setters, labs, etc. Yours sounds really smart so hopefully she will take to it really well.
