"Line breeding"
This particular matter has often been discussed, and below
is a chart which has been especially prepared for students
of line breeding.
By adhering to strict methods of selection, it is possible
by using one sire and one dam to "line breed" for a period
of 17 years.
Dam:-----------------
Sire:----------------
|
21/32 Blood
21/32 Blood to original Sire & Dam

Male No.2 mated with Female No.1. produces Group No.3. Male
No.2 mated with Female from Group 3 produces Group
No.5.
Male No.2 mated with Female from Group 5 produces
Group No.8. Male from Group 3 mated with Female No.1
produces Group No.4.
Male from Group No. 5 mated
with Female from Group No. 4 produces Group No. 7.
Male from Group No. 6 mated with Female from Group No. 4
produces Group No. 9.
Male from Group No. 7 mated with Female from Group No. 6
produces Group No. 10.
Male from Group No. 8 mated with Female from Group No. 6
produces Group No. 11.
Male from Group No. 8 mated with Female from Group No. 5
produces Group No. 13.
Male from Group No. 8 mated with Female from Group No. 7
produces Group No. 12.
Male from Group No. 9 mated with Female from Group No.11
produces Group No. 14.
Male from Group No.12 mated with Female from Group No. 9
produces Group No. 15.
Male from Group No.12 mated with Female from Group No.10
produces Group No. 16.
Male from Group No.13 mated with Female from Group No.10
produces Group No. 17.
Male from Group No.13 mated with Female from Group No.11
produces Group No.18.
The Downside of Inbreeding:
"Line breeding"
Inbreeding has been the
rule in dog breeding for the better part of two centuries.
Now It's Time for a New Approach:
Please read the article in the
November 2006.
Queensland Dog World, Page 13
"Inbreeding was once a valuable tool in shaping
today's breeds. As these have now reached
a high degree of
homogeneity, it has lost its importance and
turned into a
fatal and disastrous habit." - Hellmuth
Wachtel, PhD.
SHOW
QUALITY:
SUBSTANCE OR
ILLUSION?
By, Isabel
M. Gordon
Perhaps
the time has come to re-examine the term "show dog".
The words themselves imply that the dogs' purpose is merely to
look good.
Unfortunately, some breeders have embraced this misnomer as
their breeding objective.
If that statement disturbs you, as it should, the following
will shock (if not embarrass) you. I am not addressing the
"Backyard Breeders" from whom we have all learned not to
expect too much. My comments are directed to those whose names
have the same effect in Yorkie or Silky's - doom as E.F.
Hutton has on Wall Street; the ones to whom we refer potential
puppy buyers after warning against the small honest
breeder or "Backyard Bogeymen" The fact that recently some of our
most respected "show lines" have demonstrated serious genetic
defects and tendencies is in itself an indictment of some
reputable breeders. But in all fairness, we all stand accused of
allowing our quest for the "living standard"
to overshadow our original cause; the betterment of the breed. We share collective guilt, if not
for our actions then for our inaction as we stand by silently
watching our colleagues breeding for the ring to the
exclusion of all other considerations. So, how do we differ from
those mini; mills we look down on? In some cases, not very much.
(With the possible exception of the credibility lent by show
stats and club affiliations.)I guess we all know the truth,
but few admit this openly. Instead, we whisper our
impressions or cover up our weaknesses in a breeding
program. But now. The Devil has come to take his due.
What do we say
to a puppy buyer who calls his/her breeder, upset because
after spending $1500 on vet bills, a puppy.' dog has died of
a congenital defect? In defence can a breeder say "His
father is a B.I.S.W winner and he can talk!" or "His mother
has 500 BOB's" or how about "I'm sorry about your dog, but didn't he have a
coat to die for? " Unfortunately,
he did! And none of those fancy titles made a bit of
difference. Those of you who are at this
very moment shaking your heads in denial know that
questionable breeding practices DO take place, sometimes
with sad results for pet owners and fellow breeders as well.
It is true that ALL bloodlines have the potential for
various defects, but that is where the Breeders skill full
choice of sire or dam can make the difference.
Anyone can breed two dogs and produce puppies. However, it
takes care and sacrifice to produce quality puppies
We can never hope to purge the
breed of all defects!, but through selective breeding we can
work to stack the "genetic
deck" more in our favour over the years. This basic principal of
responsible breeding has, in some cases been lost in the
vast collection of ribbons, trophies and prestige. Whatever
the reason,
the effects are the same. Caring breeders and loving pet
owners are meeting on common ground they share; the place
they come to bury their darling little charges and their
sorrows.
To the breeders of these "Trojan Doggies", I say it's time
to get on with the true business at hand — the improvement,
refinement and above all the safeguarding of our breed as a
whole. It is
very likely that I have displeased a few, perhaps surprised
or embarrassed some.
Good! Maybe that is what we need every now and then, a
little shaking up. Granted after the final tremors, we may
find a few pedestals will stand empty, but only those whose
hold was weak. Thankfully however, we will find many
standing. Those who through the years have stood as true
bastions of the breed and who will hopefully continue to do
so for many years to come.
I have to apologize to re
print this article, but thanks to M. Gordon every honest
good Breeder should read this before his next selective
mating. Thanks Helmut.
