What wonderful news....there will be an addition to your family soon!
I am a newbie and appreciate all the info. that I have gained on yorkietalk! I am currently on a waiting list for a my first yorkie pup.
I was told by a reputable breeder that yorkie pups personalities / temperaments start to develope at eight weeks old.
When I pick I will visit for several times and not make a decision until the pup/s are at least eight weeks.
Good luck with your selection!
