    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]CONSTRUCTIVE BREEDING[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]By Lawrance D. Mahomes[/FONT]​

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]The Breeder—a person who has on his premises one or more bitches which are [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]mated for commercial purposes, for sale as pets, as game dogs, or to produce [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]potential show, field or obedience dogs. The serious breeders use the very best [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]selection of brood stock, (usually inbreed/linebreed) and are highly interested in the [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]genetics aspect of breed improvement. [/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Care and Management— in the entire process of the care and management of dogs, [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]the exercise of good judgment is involved. Upon the choice of the two dogs, male [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]and female to be mated together depends upon the future success or failure of one’s [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]dogs. If the two to be mated are ill chosen, either individually or as pertains to their [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]fitness as mates, one to the other, all the painstaking care to feed and rear the [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]resultant puppies correctly is wasted. The mating together of two dogs is the drafting [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]of the blueprints and the writing of the specification of what the puppies are to be like. [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]The puppies when they arrive, must be adequately fed and cared for in order to [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]develop them into the kinds of dogs they are in their germ plasma designed to [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]become. However, if the plans as determined in the mating are defective, just so will [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]the puppies that result from them be defective, in spite of all the good raising one can [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]give them.[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Element of Luck— the element of luck in the breeding of dogs cannot be [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]discounted, for it exists. The mating which on paper appears to be the best possible [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]may result in puppies that are poor and untypical of breed. Even less frequently, a [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]good puppy (champion mutts) may result from a chance mating together of two ill [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]chosen parents. The results are fortuitous and unusual, however the best dogs as a [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]lot come from parents carefully chosen as to their individual excellences and as to [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]their suitability as mates for each other. It is as unwise as it is unnecessary to trust [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]to luck in the breeding of dogs. Careful planning pays off in the long run, and few truly[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] excellent dogs are produced without it.[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Some breeders without any knowledge of genetics have been successful, without [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]knowing exactly why they succeeded. Some of them have adhered to beliefs in old [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]wives’ tales and to traditional concepts that science has long since exploded and [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]abandoned.[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Best to Best— breed the best to the best was an early breeder of Thoroughbreds, [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]names Robert Bakewell’s axioms. This led to the mating of superior animals [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]regardless of relationship and this frequently led to extremely close mating. He [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]thereby introduced inbreeding as a tool in breed improvement.[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Like begets Like— it is questionable whether Bakewell in practice carried this [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]adage to the extreme, some of his adherents did in latter years. Bakewell merely [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]maintained that superior animals were more likely to produce superior offspring than [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]inferior individuals. He was therefore very critical in his selection of breeding stock, [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]not only as to appearance but as to performance and, as to breeding performance. [/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Inbreeding— inbreeding may be defined as the mating of animals which are more [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]closely related than the average of the breed. By inbreeding the number of ancestors [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]is necessarily reduced, but the number of ancestral places remains the same.[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Reasons for close breeding— there are several rather specific reasons for [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]inbreeding. The first is the purification of bloodiness. Inbreeding induces segregation;[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] hence continued inbreeding accompanied by rigorous selection for certain [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]characteristics is the quickest and most certain method of fixing desirable traits, [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]undesirable traits are, however, fixed with as much rapidity and sometimes it appears [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]they are fixed with even more ease than desirable traits; hence the selection should [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]always be directed at the traits sought in the line after they are purified. Inbreeding [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]neither adds nor subtracts from the line, it merely brings out what is in the bred and [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]offers the breeder the opportunity of selecting more intensive than he otherwise would.[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] It is a mistake to start inbreeding until one has reason to believe that he has [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]something good in the line. On the other hand, it’s a mistake to delay inbreeding after[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] something good has been found because each outcross eliminates exactly one-half [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]of the hereditary material already in the breed.[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Undesirable Traits— undesirable traits, as mention earlier, come with inbreeding. [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Therefore corrective mating (outcross) has their place in constructive breeding. The [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]corrective mating should be made for the specific purpose of correcting some definite [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]defect in a stock or strain. The outcross needs to be followed by a certain amount of [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]inbreeding in order to fix the character in the strain; otherwise it is likely to be lost in [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]subsequent outcrossings.[/FONT]

    There seems to be some helpful info here. However I must object ot the first line saying the definition of a breeder as someone who might breed to produce pets (and I won't touch "game dogs") ...

    If a one's goal is only to produce pets, then IMO they are not just a breeder, but one of those special "unethical backyard" breeders.
