to NOT to...IT ONLY TAKES ONE TIME.
The first is dangerous.

1. You are obviously inexperienced, you should post about finding a mentor.
An experienced, YTCA member, AKC showing exhibiting breading mentor-not a hobby breeder or BYB or someone who breeds another AKC showing breed, say miniature schnauzers-not all breeds are the say you need breed specific knowledge for breeding.
Even if you choose to breed another variation of Yorkie (let's say you have Parti females) wouldn't you learn more and be 'improving the breed standard' if you learned all from a respected YTCA member? AKC is the only respected reputable registry in America. Period.

2. You need to learn about breeding, care, conformity, health, training, showing, matching/mating, whelping. All he aforementioned, prior to considering if you can;

3. all prior to considering if you can; afford to breed, financially, emotionally, time wise.

4.You need AKC full registration breeding rights on your females, they should be health checked, certified I.e. OFA, CHIC, CERF and then you need to know their lineage and appropriately mate them with males of the same quality: not just any random purebred Yorkie.

5. You need the funds & support system around you to support the pregnancy, delivery, whelping, puppy training

6. Finding homes-well the mentor should have taught you how to do this, have a health guarantee in place, re-homing clause, how to register your litter, home them on limited registrations, etc etc plan for unadopted pups, returned pups, sick pups.

7. I think every breeder should first volunteer at rescue & animal control for their own education prior to breeding.
