Yorkshire terriers are among the smallest breed of dogs. They are well loved because of their size and temperament. Yorkies are purebred dogs so it is important to find one that is close to the breed standard and free from any genetic defects. Learning the basics of how to breed yorkies is not easy at all. If you choose a breed that is a health risk, it is likely that you would jeopardize the whole breed as well.
When learning how to breed yorkies, you first need to find out if the female yorkie is healthy enough for breeding. You need to understand that yorkies are susceptible to several genetic conditions like hydrocephalus, hypoglycemia, and luxating patellas. Check with your vet if the female has no genetic defects before breeding.
When the vet has cleared your female yorkie, choose a male that matches the characteristics of your female. Remember that yorkies differ in size so complementing the size of your female with a male can prevent any problems during delivery. Likewise, see to it that the male is free from any genetic or communicable diseases.
Another way of breeding yorkies is to look for one that had a history of successful breeding or has reached a minimum of 18 months. In general, this is the proper time for any health issues to have surfaced. At the same time, this is the time when the female yorkie has already one estrus. The proper time for breeding female yorkies is during their second estrus.
Before breeding, check the female yorkie for signs of being in heat. You will know it when the vulva of the female is swollen and noticeably larger than the normal size. Likewise, there is occasional discharge of blood. Finally, females are ripe for breeding when they show change in temperament.
When this happens, do not breed the female right away. Wait for about 10 days before breeding. This is usually the time when the female is fertile. They are usually unwilling to mate before their fertility period.

When the female yorkie has already reached their fertile stage, this is the time to put them together with the male. If there are no health issues and the female is willing to mount, then the dogs are already aware of what they need to do. How to breed yorkies may be a complicated subject, but the most important thing to remember is that educated breeders rarely let caution to the wind, or let nature take its course. Instead, such breeders make sure that yorkie breeding is done as a structured process.

If the female becomes pregnant, her swollen vulva does not disappear right away even after her cycle is finished. The bloody discharge may have already disappeared but the vulva is still swollen. At this stage, she should be taken to the vet for prenatal care.
Learning how to breed a yorkie can be easy by following the steps mentioned above.
