1. You could, but you should not, as it's horrifically irresponsible of you to be selling the offspring of two dogs when you have no idea of the health of their parents. Not to mention, the price of vet care alone would probably be more than you could make selling the puppies, since papered and registered labs are a dime a dozen. I've seen them sell for as little as $50 in my area of the country. If there was a problem during the whelping, you might spend $1000 or more on a c-section... or just risk losing your female outright from complications.
2. You can't, not with a legitimate registry. Or rather, you can't get them registered without neutering/spaying them first, the AKC will give them Indefinite listing privelede if they're altered.
3. You can't, without the parents of your dogs being registered or your dogs being registered.
Never trust a tall dwarf... he's lying about something.
Thank you for all the input. I was just wondering really if and how I could go about getting a pedigree and if I had to to that from a vet. Also, if I could register them. - Without this I would not breed them.
