Brackett Principle #6: Know What to Expect through Inheritance!

“…ONLY those breeders knowledgeable in what constitutes a near-perfect specimen of the breed, as well as those having information on what to hope for, and look out for, through inheritance factors, should even THINK of doing closed-up breeding on them.”[i]

Mr.Brackett employed a three-step procedure for this component of visualizing what a proposed breeding might bring forth.  First, the breeder must know what constitutes a good GSD according to the breed standard.  Next, the breeder must be knowledgeable of the pedigrees of the potential mates.  This naturally leads into the third step of knowing the characteristics (attributes and faults) of as many of the dogs in the pedigree as possible.

It is imperative to be certain to select near faultless dogs as foundation stock!  It will be very difficult, if not impossible; to implement planned breeding using mediocre stock.  Brackett was adamant that if a beginner, or any breeder for that matter, discovers (obviously through gained knowledge and experience) that they possess mediocre stock; then there is only one course of action—“Cull relentlessly!”

Even when the proposed mating matches very good dogs, never mate two dogs with similar faults.  This action would only heighten the probability of reproducing that very fault.

This principle rests upon knowing both the “phenotype” and the “genotype” of the dogs being used in your breeding program.   Phenotype can be defined as the “outward, physical manifestation of the organism. These are the physical parts, . . .anything that is part of the observable structure, function or behavior of a living organism.”[ii]

Genotype can be defined as the "internally coded, inheritable information carried by all living organisms. This stored information is used as a ‘blueprint’ or set of instructions for building and maintaining a living creature. These instructions are found within almost all cells (the ‘internal’ part), they are written in a coded language (the genetic code), they are copied at the time of cell division or reproduction and are passed from one generation to the next ("inheritable").”[iii]

Brackett goes so far as to suggest that many beginners are “stuck” and have little hope of moving away from mediocrity.  He wrote that “few indeed are those who have more than one bitch and, more often than not, that one not such a specimen as a knowledgeable fancier of the breed would select as a foundation brood matron.”[iv]  They are “stuck” with the stock they have and therefore are determined to make use of what they have.  The reasons for breeding from such mediocre stock may be the result of affection for the bitch, insufficient financial ability to purchase something better, the lack of knowledge to be aware of what constitutes a good GSD and the inability to set a vision in regards to developing a breeding program or planned breeding.  Brackett advocated beginning with something much better than an ordinary, run-of-the-mill specimen.
