May I ask what for? If you think it's good for her, it isn't. A bitch does not have to have puppies ONCE to be healthy. It is a myth.
If you hope to make money off her, think again- you should know first of all that you probably have no way of knowing if your dog and/or the possible father carry any bad genes that may affect their offspring.
You should make these lab tests to determine if you dog is indeed healthy to breed, and does not carry any undesirable traits. You probably won't..
Because that costs a lot of money. But if you don't do that you dog may have puppies that later will grow into sickly adults or aggressive adults.
I have a dog like that- a home breed Aussie who is blind in one eye and which eye is now filled with blood- from a genetic trait characteristic for this breed. Both parents were "so heatlhy" !!! no cure for this eye except removing it.
Another Aussie I have is fear aggressive toward other dogs and it is not pleasant to go for leash off area with him and yet we must because it is Aussie it has to run freely a lot.
So please think twice about wanting to breed your dog, please, and also look up Google for your breed and see if they have any "rescue".
You might think because you have pure breed then you will readily find for them homes- which is another question- are you sure you will be able to find GOOD homes for all puppies?- but just because a dog is purebreed might not ensure finding him a home that easily.
I have pure breed Aussies, not with "papers" but purebreed nevertheless, and look at the rescue:
