Whats the importance

Keeping a dog in heat can be very stresfull for both you and the dog. You might have to ward off male dogs from your yard, even if she stays inside and you have a fence, they are amazing how they can find their way in when they smell a bitch in heat.
Not to mention the high risk of cancers of the reproductive system.
She'll be happyer and less moody if spayed before her first heat at around 5 or 6 months.
Breeding is very time consuming and expensive. Tests so you don't produce a litter of unhealthy puppies are expensive but the vet bills for a sick puppy are even higher.
The people who would have taken a dog from a shelter take your dog's pups instead, and then the pups in the shelter don't have a home.

My dog, Visa, isn't spayed because I show her, and trust me, having an unspayed dog is NOT for everyone. Most unspayed females become dog-aggressive. They can go through pseudo (false) pregnancies which are very stressful for her -- she will gain weight, her breasts will swell and she will lactate, nest, etc. Females in heat become very annoying. They whine constantly, they pace, they always want outdoors (so they can find a mate), they hump other dogs, people, etc. They start to mark (territorial peeing), and they become total freaks. The judge at Visa's last show excused her behaviour when she was acting like a mental freak because she was in heat. Unless you plan on showing or REPUTABLY breeding, having your dog spayed is the best thing you can do for her and you. Remember that breeding costs thousands of dollars and you will never make more than you spend, if you do it properly.

The only reason I see someone would have a reason to breed would be if the parents are in perfect health and if they have something to give.

Gr.. I can't really get out what I'm trying to say.. It's like this:

The only reason you should breed Border Collies if it's parents proove themselves to be amazing working dogs, because that is what they are bred to do.

Personally, and no offense meaned, I would spay your Yorkie. Of course, everyone wants a puppy. All puppies are adorable. There is no such thing as an ugly puppy. But when it's all grown up, not housetrained, no basic obedience is down, no one wants it.

You have no real 100% guarantee when you sell a puppy that the buyers are going to live up to their word one year or more down the line.

Sad, isn't it?

I agree with the other posts I just had a couple things to add.

It can be deadly to your dog if she were to accidently get pregnant by a larger dog. She wouldn't be able to deliver the puppies. Even a c-section won't gurantee live puppies, they may be so large that the mother can't carry them full term.

Even if you do decide to breed (which shouldn't be done unless your dog is a PERFECT example of the breed & you are ONLY breedeing to better the breed) but you still take the chances of an emergance c-section, still-born puppies, the mother rejects the puppies & you are forced to care for them, the list can go on & on.

An unspayed female, especially an older unspayed femal has a greater risk of Pyometra, a eadly uterous infection. Suregery must be done ASAP or you risk your dogs life.

And of course the already mentioned health probelms associated with cancers & the like.
