I know a lot of people want to breed their Yorkies, but the truth of it is, Yorkies are very hard to safely breed. Once man domesticates an animal, they no longer are a wild animal that can breed and deliver on their own; they need man to help with the process. In nature, there's a rule "survival of the fittest," and only the strongest and healthiest gets to breed, weak and sickly animals don't breed. This allows for the offspring to be healthy. However, this isn’t true with domesticated pets, you can't tell by just looking at your dog, if she's carrying genetic illnesses that may show up in a couple of years. The Yorkshire Terrier has so many genetic illness because backyard breeders don't do the required health testing, and there are very specific health tests that you should do before you breed. Also, you should never breed unless you are sure you can take care of every offspring your dog produces for the life of the dogs. Remember, you might not be able to sell all the offspring, or they might be returned to you, should a genetic illness pop up and someone can't afford to pay for needed surgery. Then it would be your responsibility to pay for the surgery the dogs needed. You should never breed a dog, because you don't have the money to buy one. Breeding is a very expensive hobby and unless it's a passion, where you want to learn everything you can about it, please don't consider breeding your little girl, let her be a pet, not a money maker.
