BREEDING BETTER
DOGS requires a basic understanding of genetics and how to
apply them. It requires study of your breed to understand good
breed type and structure.

There is an old saying: be careful
what you do...
as it will always come back to haunt
you in the whelping box!

Good breeding requires
understanding and applying the terms of linebreeding, inbreeding and
outcrossing.
We should know exactly what we mean
when we talk of inbreeding, line breeding and
out-crossing.
Line breeding is
mating animals who are closely related to the same ancestor,
preferably one whose type it is desired to obtain in the resultant
progeny. In other words, it is accomplished by using for parents
dogs who are closely related to that ancestor, but are little, if at
all, related to each other through any other
ancestors.
Inbreeding implies a much closer relationship
between the mating pair than does line breeding. Instead of
involving second, third or more distant generations, it is generally
understood to have to do with only four relationships—son to mother,
father to daughter, brother to sister, half-brother to half-sister
(both having the same sire and different darns, or the same dame and
different sires). It should be remembered that when mating the
progeny of two litters each having the same parents (from repeated
matings, for instance), one is mating full blood brothers and
sisters. That too is inbreeding.
Why Inbred or Line
bred?
The purpose of both line breeding and
inbreeding is to bring about breed improvement to get the best that
is possible out of ones matings and to upgrade his
stock.
Advantages of
Inbreeding
When superior animals are used, it is the
most powerful and sure way known of making the most of their
excellence and perpetuating it. It is the method by which the
highest possible percentage of the blood of an exceptional dog, or
of a particularly fortunate "nick", can be kept, fused into, and
finally made to influence an entire line of descent. If continued,
the outside blood disappears and the pedigree is quickly loaded to
an almost unlimited extent by the blood of a single animal, or two
at the most. In practice it is usually that of a sire. Inbreeding is
not so much a matter of originating excellence as of holding and
making the greatest use of it when it appears.
Disadvantages of
Inbreeding
Although the doubling up and intensifying of
characteristics by this method of breeding insures results that are
more probable than possible and, if continued long enough, are a
certainty, it works the same for one trait as another, both
good and bad. It affects all characteristics of the animals
involved. That is why, unless a breeder knows a good individual
of his breed when he sees one, or possesses the right stock to start
with, inbreeding can bring disaster.
ANY characteristic can be bred up or down,
strengthened or weakened, by this method of breeding. Some of what
we know about the results of inbreeding in animals comes from the
scattered and irregularly reported experiences of breeders. It is
difficult to be at all sure that the evidence against inbreeding
came from using animals who were typical of their breed and should
have been inbred upon at the outset. There is also the question of
whether one hears of the usual effects of such breedings or only of
the exceptionally bad ones. Anything undesirable which does appear
is apt to be blamed on inbreeding, in spite of the fact that equally
bad results often occur when no inbreeding has been done.
The belief, and some uninformed breeders’
contention, that inbreeding and line breeding per se will cause
either physical or mental deterioration is a fallacy many times
proven.
What is outcrossing?
When we outcross, we take two completely unrelated lines and breed them
together. This is what I call "Jackpot
mating". The chances of getting something good out of such a
breeding are remote. However, if the breeder is planning ahead, this
may merely be a step in a longer term strategy. For outcrossing to
work, the next logical step is to breed close again to the line.
When you outcross you basically leave it up
to great randomness about what the babies will look like. You will
NOT get the best charactertics of the mother and the father. In all
likelihood, you will get a very average looking litter or worse.
In order to outcross successfully, you have
to understand that within every breed there are different types.
One of the fallacies of cross breeding is
that the genetic diversity you get will give you a better pup. This
is completely unfounded in any scientific study. What you do get, is
a lot of "unknowns".
If you do not have the competencies required to facilitate the
breeding of your bitch, the raising of puppies, and the placement of
puppies, it is irresponsible and unethical to breed until you
have.
