hi and welcome. i am sorry for your loss! I cant relate in a way to the fear of yorkies (i got myself and my friend a yorkie each from the same breeder, her's died 3 months later from LS!!) i did contemplate getting a different breed when ready to get a baby sister for my Ziggy (my friend is going to get a Jack Russel) but I just really want to find a good breeder (and i believe I have).
I think ANY breeder can be good or bad, not just because of the actual breed. I think you should spend alot of time doing research and get advise on breeders on here too. And I'm sure you'll find a good breeder and a healthy new baby!
Good luck
