Real, scientific facts as they are, I will continue to s/n yorkies that come to me intact at six months .. of course that is for puppies which I don't always have.
I will also advocate for it whether you all think it is emotional or whatever you think.
I have seen what I believe are personal agendas (Heaven only knows what they are, but I believe they are) all over the place on this thread....and in my mind it is not what I believe is in the best interest of this breed that has clearly been almost destroyed by bad breeding. Call in unscientific as you may...emotional as you may. I call it responsible.
