To the OP, unless you do health testing, and then get a title on your dog, your best bet is to not breed. To do it right will cost you more than you could ever get in stud fees unless he is phenomenal.
To Rosie.. wow. No. Contact BRAT and adopt a dog. The fair thing to your dog is to love her, spay her and not risk cancer, dying or complications from whelping and other issues. The responsible thing to your children isn't to become a backyard breeder creating puppies, but to show them you actually CARE about animals and not produce more. Unless of course you are willing to fork over the money required to do all the health testing (this is not your vet saying "she's fine" but rather hip xrays, Fanconi DNA, thyroid, heart etc!) AND pay for stud service to a dog who has also been tested (good luck with that– most reputable stud owners don't just breed to anyone).
