The only reason to be breeding purebred dogs is to preserve the best qualities of the breed.  Breeding to supply any market is not a justification.

You need to do all of your breeding with the best interests of the breed in mind.  Never your pocket book.

For this you need to be a serious student of the breed and devote years of your life to it.  No "in one day out the other".  As a beginner you need to engross yourself in the breed as much as possible and ideally find a suitable mentor.

Every breeding should be done with the intent of keeping something from it to further your own breeding program.

You do need to keep track of all you produce whether pet or show, to know how your breeding program is working.

All pet dogs need to go on a spay neuter contract, and all show puppies need to go on a contract that will not allow breeding unless the dog lives up to the quality intended and passes all health checks and certification necessary for that breed.

Co-ownerships allow you a certain amount of control in this regard because they require your signature in order that puppies be registered.

If a prospective breeder does not want to do this, then I am sorry but they will have to mess with someone else's dogs not mine!!

 In order to be a serious breeder, one must show and compete.

In my ideal world one could not sell dogs.  Dogs would only be able to be given as cherished gifts to deserving individuals.  This would eliminate the whole pet mill and back-yard breeding industry as they could not make any money.

Every breeder owes it to the Breed, as well to themselves, to be involved with rescue.

Every breeder should be prepared to take any dog back for whatever reason.  If they do not have the space, then they need to be prepared to make other arrangements.  But take back they must!
