Be Honest in all aspects of education and the transfer of dogs to know owners.
Practice responsible breeding as described below.  If you are NOT ready to do this you should NOT breed!
The animals you select for breeding today will have an impact on the breed for many years to come. Keep that thought firmly in mind when you choose breeding stock.  Know your breeds health issues.
The most visible ads are not always the best stock, nor is the most highest priced animals always the best stock.
Don't allow personal feelings to influence your choice of breeding. The right dog for your breeding program is the
best dog,
whoever owns it.
Discard the old "clich'e" about the litter mate of that great producer being just as good to breed too. Litter mates
seldom have the same genetic make-up.
You can choose only two individuals per gene ration. Choose only the best, because you will have to wait for another generation to improve what you start with. Breed only if you expect the prodigy (pups) to be better than both
parents.
A pedigree is a tool to help you learn the good and bad attributes that your dog is likely to exhibit or reproduce.
Remember a pedigree is
only as good as the dog it represents.
Hereditary traits are inherited equally from both parents. Do NOT breed a dog that may pass on serious genetic disease!
Be honest with yourself. There are no perfect dogs (or bitches) nor are there perfect producers. You cannot do a
competent job of breeding if you
cannot recognize the faults and virtues of the dogs you plan to breed.  You want to produce pups that will be a source of joy for it's owner not sorrow!  Avoid causing heartache!
Breed for a total dog, not just one or two characteristics. Don't follow fads in your breed, because they are usually
meant to emphasize one or two features of the dog at the expense of the soundness and function of the whole.
Remember that skeletal defects are the most difficult to change.
Keep in mind that quality is a combination of soundness (temperament) and function. It is not merely the lack of faults, but the positive presence of virtues. It is the whole dog that counts. 
Don't bother with a good dog that cannot produce quality pups. Well, enjoy him or her for the beauty that he/she
represents but don't use him in a breeding program.
A STUD dog should throw himself CONSISTANTLY. If he does not, he is a nice dog, but not a true stud dog.
Quality does not mean quantity. Quality is produced by: careful study, having a good mental picture of what you are
trying to achieve, and having the patience to wait until the right breeding stock is available
. You must evaluate what
you have already produced.
If the worst puppy in your last litter is no better than the worst puppy in your first litter, you are not making
progress.
This should consider what you are breeding for, and perhaps  make this  your last litter.
There is no such thing as "pet quality". That's NOT to say that many pups don't go to "pet" homes.  "Pet Quality"
animals are examples of what is WRONG in what you are breeding. You should always be striving to CORRECT
these faults. IF you give away or sell a *pet quality* animal, BE SURE to have a solid spay/neuter agreement so
that the animal won't add more poorly bred animals in the breeds gene pool.
Care about each pup you bring into this world, treat it as part of your extended family. Thoroughly screen all perspective homes.
Always be willing to take in or help place dogs that you bred. Brining them into the world you are ultimately responsible in making sure they never land in a shelter or rescue.  Always back your puppies with a sound guarantee of quality and health.  48-72 hours is hardly enough time for problems to appear.  If you don't feel you can gauarntee these things at least a yr., then chances are you question your breeding stock.
Research and interact with other breeders.  Our most valuable tool is EXPERIENCE!
Remember that Responsible Ownership Starts with Breeders
screening and guiding buyers! 
The Breeds Future is in Our Hands.
With media hysteria and BSL on the rise, we good breeders and  owners, find ourselves endlessly having to defend our breed.  Every bad story and headline damage our dogs even further. Irresponsible and uneducated breeders and owners have done almost as much damage to these dogs as dog fighters have. The Pit Bull is an exceptional breed that requires exceptional dedication and ownership.
Remain available as a resource, educate,  advise & support owners of the breed.
Require deposits to encourage commitment to pups spoken for.
