Welcome to YT! Sorry to hear about what happened to your baby...
When I first started looking, I contacted several breeders on the Canadian equivalent of
Yorkshire Terrier Dog Breeders- Yorkie Puppies
I know in this day and age, most people like websites, but I found that a lot of the good reputable breeders who are more focused on showing than running a Yorkie puppy business don't have websites (which makes sense to me). Try calling them or emailing them with your interest. It's a good starting point. Then, somewhere down the road ask when it'd be convenient to meet with them either at their home or if they're attending any local shows. It's easier if you're willing to travel outside of your state too, depending on availability...
Good luck in your search! Make sure you don't rush into it. It's well worth it to have patience and
find the perfect breeder (rather than finding the cutest puppy that a bad breeder tries to 'sell' to you).
