1. Remember that 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.

2. You can choose only two individuals per generation. 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 progeny to be better than both parents.

3. You cannot expect statistical predictions to hold true in a small number of animals (as in one litter of puppies). Statistics only apply to large     
    populations.

4. A pedigree is a tool to help you learn the good and bad attributes that your dog is likely to exhibit or reproduce. A pedigree is only as good     
    as the dog it represents.

5. 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.

6. Quality does not mean quantity. Quality is produced by careful study, having a good mental picture of what you are trying to achieve, having  
    patience to wait until the right breeding stock is available and to evaluate what you have already produced, and above all, having a breeding   
    plan that is at least three generations ahead of the breeding you do today.

7. Remember that skeletal defects are the most difficult to change.

8. Don't bother with a good dog that cannot produce well. Enjoy him (or her) for the beauty that he represents but don't use him in a breeding      
    program.

9. Use out-crosses very sparingly. For each desirable characteristic you acquire, you will get many bad traits that you will have to eliminate in    
     succeeding generations.

10. Inbreeding is a valuable tool, being the fastest method to set good characteristics and type. It brings to light hidden traits that need to be      
      eliminated from the breed.

11. Breeding does not "create" anything. What you get is what was there to begin with. It may have been hidden for many generations, but it     
      was there.

12. Discard the old cliché about the littermate of that great producer being just as good to breed to. Littermates seldom have the same genetic   
      make-up.

13. 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.

14. Hereditary traits are inherited equally from both parents. Do not expect to solve all of your problems in one generation.

15. If the worst puppy in your last litter is no better than the worst puppy in your first litter, you are not making progress. Your last litter should  
       be your last litter.

16. If the best puppy in your last litter is no better than the best puppy in your first litter, you are not making progress. Your last litter should be
       your last litter.

17. Do not choose a breeding animal by either the best or the worst that he (or she) has produced. Evaluate the total get by the attributes of the
       majority.

18. Keep in mind that quality is a combination of soundness and function. It is not merely the lack of faults, but the positive presence of virtues.
       It is the whole dog that counts.

19. Don't allow personal feelings to influence your choice of breeding stock. The right dog for your breeding program is the right dog, whoever
owns it. Don't ever decry a good dog; they are too rare and wonderful to be demeaned by pettiness.

20. Don't be satisfied with anything but the best. The second best is never good enough.
20 Principles of Breeding Better Dogs
by
Raymond H. Oppenheimer


There are a vast number of different breeding methods, some good, some bad.  I should never presume to try to tell fanciers what is the right
method because there is no such thing.  Outstanding success can be achieved and has been achieved in a variety of different ways.  So all I am
going to do is to make some suggestions which I think helpful and to warn against certain pitfalls which trap too many of the unwary.

(Note: Oppenheimer was a great Bull Terrier breeder.  But what he says applies to Schipperkes (and other breeds), too.)

1 Don't make use of indiscriminate outcrosses.  A judicious outcross can be of great value, an injudicious one can produce an aggregation of      
   every imaginable fault in the breed.

2 Don't line breed just for the sake of line breeding.  Line breeding with complementary types can bring great rewards; with unsuitable ones it   
    will lead to immediate disaster.

3 Don't take advice from people who have always been unsuccessful breeders.  If their opinions were worth having they would have proved it    
    by their success.

4 Don't believe the popular cliche about the brother or sister of the great champion being just as good to breed from.  For every one that is,       
    hundreds are not.  It depends on the animal concerned.

5 Don't credit your own dogs with virtues they don't possess.  Self-deceit is a stepping-stone to failure.

6 Don't breed from mediocrities; the absence of a fault does not in any way signify the presence of its corresponding virtue.

7  Don't try to line breed two dogs at the same time; you will end by line breeding to neither.

8  Don't assess the worth of a stud dog by his inferior progeny.  All stud dogs sire rubbish at times; what matters are how good their best            
    efforts are.
9 Don't allow personal feelings to influence your choice of a stud dog.  The right dog for your bitch is the right dog whoever owns it.

10 Don't allow admiration of a stud dog to blind you to his faults.  If you do you will soon be the victim of autointoxication.

11 Don't mate together animals which share the same faults.  You are asking for trouble if you do.

12 Don't forget that it is the whole dog that counts.  If you forget one virtue while searching for another you will pay for it.

13 Don't search for the perfect dog as a mate for your bitch.  The perfect dog (or bitch) doesn't exist, never has or never will!

14 Don't be frightened of breeding from animals that have obvious faults so long as they have compensating virtues.  A lack of virtue is far the  
     greatest fault of all.

15 Don't mate together non-complementary types.  An ability to recognize type at a glance is a breeder's greatest gift; ask the successful          
     breeders to explain this subject - there is no other way of learning.  (I would define non-complementary types as ones which have the same    
     faults and lack the same virtues.)

16 Don't forget the necessity to preserve head quality.  It will vanish like a dream if you do.

17 Don't forget that substance plus quality should be one of your aims.  Any fool can breed one without the other.

18 Don't forget that a great head plus soundness should be one of your aims.  Many people can never breed either!

19 Don't ever try to decry a great dog.  A thing of beauty is not only a joy forever but also a great price and pleasure to all true lovers of the      
     breed.

20 Don't be satisfied with anything but the best.  The second best is never good enough.
