From
the history of the pembroke corgi we can read about the little bobtail
dog that has been bred on Welsh farms through centuries. We know that in
the beginning of this century the majority of pembrokes were born with
bobtails. I
believe that the period in the beginning of this century, when the
pembroke and the cardigan were registered in the Kennel Club as one
breed and were also interbred to a certain extent, is the reason why the
bobtails are so few today. When the breeds were separated I 1934, the
longtail gene had been introduced to the pembroke population and the
breeders docked the puppies that were born with long tails as the
standard described a short tail. The
bobtail gene has proven to be a dominant gene, and it is very easy to
loose a dominant gene if you are not aware of the genetic rules. If you
want to keep a dominant gene in your population, one of the parents have
to carry the gene, otherwise you will loose it. It is easy to understand
how the breeders would hold on to their best puppy regardless of it
being bobtail or longtail as they were all docked anyway, and how the
amount of bobtail dogs in the population gradually could decrease. When
we got the docking ban in Norway, I am happy to say that most of the
corgi breeders in Norway agreed that they wanted to take part in the
project of trying to reintroduce the bobtail gene into our corgi
population. This
has been a necessity as our population is so small that we needed to use
all our breeding material to keep our breed healthy while introducing
the bobtail gene. Although I had bobtails born in my first litter in
1968, and also in a litter in the mid seventies, we were not able to
find any dogs of our old lines that could be used when we got the
docking ban. This
meant that we had to import dog from England where Mrs. Peggy Gamble (Blands)
and Miss Patsy Hewan (Stormerbanks) had just started a project of
reintroducing the bobtail gene to the breed. Miss
Patsy Hewan at that time run a very large kennel, and over the years she
had managed to keep the bobtail gene in her stock. Peggy Gamble bought a
bitch from Patsy, Stormerbanks Bobs, and Peter Hopwood (Jofren) used her
uncle Stormerbanks Barnaby Bear to introduce bobtails into his line. As
Patsy Hewan died shortly after they agreed to start the bobtail project,
the Blands and Jofren kennels were the ones that carried out the pioneer
work, and Stormerbanks Bobs and S. Barnaby Bear will be in the pedigrees
of most bobtailed dogs in England, and in Norway. Miss Sarah Taylor (Bymil)
and Miss Leila Moore (Kaytop) also had litters containing bobtail
puppies sired by Kaytop Ming, but it seems the bobtail puppies have not
been used for breeding and that line seems to be lost. I
know that Peggy Gamble also gave her stud dogs for free to some pet
owners with bobtail dogs, but I do not think that they have bred on, at
least I do not know of any. There
are many hypotheses of defects that are supposed to be linked to the
bobtail gene. However, as far as I know there has been no serious
research into this matter, and the Norwegian corgi breeders were not
willing to accept these theories as long as they were not supported by
scientific proof. We could not understand why dogs should be so
different than other wild animals or even humans, which live and
reproduce happily with their short tails. We
must admit that the first bobtail dogs that were imported to Norway were
not of the quality that we were used to, and we had to take a few steps
backwards quality wise. This because we had to use our best bobtails
even though there might be better longtails available.
For
many years we have done mainly longtail/bobtail matings to try and
preserve most of our quality, and have tried to import breeding material
and find stud dogs that could help us to improve our quality. It has
been a long and difficult process, but the last three or four years I am
happy to say that I think the quality has improved very much, and our
bobtail corgis has won well at group level, and I myself have won both
BIS progeny group and breeders group at big International shows with all
bobtails. We
have not experienced any of the predicted defects to pop up in our breed.
It is as sound as it has always been. Some years ago the Norwegian Welsh
Corgi Klubb together with Norsk Kennel Klub and the Veterinary institute,
made an x-ray study of the spine of a random selection of bobtail dogs
from double bobtail matings. The
conclusion to the study was that there was no indication what so ever to
say that the bobtail gene should be responsible for any spinal
deformities. In
nearly every litter we will have puppies with different tail length.
Some can be long, some half long and some quite short. We do not know
why the bobtails appear with different length, but it is a fact that the
tail is the only body structure that will appear with different number
of bones, this is also true for the longtails. I
believe that in the same way as some terrier breeders select for shorter
longtails, we can select for shorter bobtails. So far it is difficult to
predict the length of tail of our bobtail puppies. I have mated longtail/bobtail
and have got puppies with very short tails, and I have mated
bobtail/bobtail and have got half long tails. Some of the bobtails, but
also the longtails can be seen with a kink on their tail. Our x-ray
project also involved some of these dogs, and there was no indication
that this would also affect spinal vertebra. So far we do not take any
notice of these kinks when breeding, as we have not seen them to cause
any problems. We
have not yet found the dog or bitch that will produce only bobtails.
Because not all bobtail puppies from bobtail/bobtail matings are
suitable for breeding, the Norwegian Welsh Corgi Klub, together with
geneticists from England, The Norwegian Veterinary Institute, and the
Norwegian Kennel Klub, some years ago made a project of blood testing
our bobtails to try and find the homozygote bobtail through gene
research. The
locus for the tail gene was found, but from our random selection of dogs
from bobtail/bobtail matings, the scientists were not able to find a
homozygote. Also dead bobtail puppies were tested but even in this
selection there were no homozygotes. The scientific conclusion was that
the bobtail gene that produces bobtails in Pembroke corgis is a lethal
gene. This gives no support to my working theory that the longtail gene
was introduced by the interbreeding with cardigans, or explain how the
welsh farmers managed to maintain the percentage of bobtail dogs so
high, as there is no reason to believe that they knew that one of the
parents had to be a bobtail to produce bobtails. Even
though the scientists find it statistically likely that the bobtail gene
is a lethal gen, I think that historic facts gives some support for my
theory, and I still hang on to the hope of sometime finding the dog that
will only produce bobtails. There is also the possibility that the
bobtail gene has undergone changes over the years, and has become a
lethal gene even though not being so originally. If
the conclusion of the scientists is correct, and this is the basis for
our This
of cause can be explained by the different fertility of different bitch
lines, and does not exclude the possibility of the bobtail gene being a
lethal gene. Our aim, in time to produce only bobtail pembroke corgis
seem to be impossible. There should, however, be no reasons for not
doing bobtail/bobtail matings, other than a possible ethical view that
one will not produce a litter were there is a possibility that one or
maybe two of the puppies will be absorbed in mothers womb, and never
come to life. There should be no reason to expect any physical defects
resulting from bobtail breeding either bobtail/bobtail, or bobtail/longtail.
The
Scandinavian countries were the first to have the docking ban, and the
breeders here have been leading the way in seriously trying to breed the
bobtails back into the breed. Over the last ten years many more
countries have got the docking ban imposed on them, and many corgi
breeders in many of these countries have joined the Scandinavian
breeders in their wish to maintain their short tailed corgis. In
2004 docking was also banned in Australia that is one of the really
influential countries when it comes to corgi breeding. Some breeders
have been breeding bobtails there for many years, but like in England
the discussion is loud, and many breeders are all against. An extended
interest for bobtail breeding in a country like Australia would be of
great help to all the bobtail breeders in countries with numerically
small corgi populations. Imported bobtails from Australia could help us
increase our gene pool to keep our breed healthy with no inbreeding
depression, which is a much larger threat to the breed than defects
resulting from bobtail breeding.
