I have to say, somewhat in mrs merch's defense....
Because we are from the same down, I KNOW how rare it is around here to happen upon a breeder who DOESN'T let their pups go early. It is very much the common practice here to release pups at young as 6 weeks. Unless you take it upon yourself to learn about Yorkies VERY thoroughly first, you'd have no indication that there are huge risks invovled with getting one young. I remember that years ago when I was researching before I got my furbutts, learning that threw me for a loop too because it's honestly just not something you hear 'around these parts.'
Unfortunately, our state is one that has yet to adopt a minimum age release law as so many others have.
