You know one of the first rules of correct breeding is this;

Just because a dog "can" be bred doesn't mean they should be bred!

If you rescued this dog from a shelter, I know of none that allow intact dogs to be adopted. If you rescued this dog from a private party that DID NOT want that dog bred ever again, then why would you breed these dogs?
It is unhighly un-ethical to say the least.

Future owners of these pups should be made fully aware of the health status of both parents -(likely unknown) as I can almost guarantee you did not do all the pre-breeding screening tests.

Literally you are asking future owners to adopt/buy what could be a health time bomb!

In terms of selling these puppies - I would not even consider one for free, from untested parents, with a breeder that seems as un-knowledgeable as yourself.
