Over many years I have heard of the occasional litter
being apparently affected by this disease, indeed I have been
contacted by several of the breeders of such litters, and I felt
somewhat lacking in knowledge and experience to offer them any
meaningful advice, other than in the manner they dealt with
devastated owners who had lost their much loved pet GSD puppy, in
most cases between 4 and 6 months of age.
During the last year or so there has been a spate of
litters affected, where all or the majority of each litter have
died in the same manner. Kidney failure through underdeveloped
kidneys.
Having had an enquiry to purchase one of my puppies
from a couple who had very recently lost their adored 5 month old
male GSD puppy, I invited them to come and visit to view my puppy,
which they bought. However I found it a very emotional experience
when they explained how they had lost their previous puppy aged 5
months with kidney failure, and how they were told by the breeder
that four of the litter of seven had died of the same cause, and
more deaths were possible amongst the remainder. This lovely couple
were devastated and in tears over their tragic loss. (see
the story of Buster below)
There and then I decided to start some very serious
and thorough research into this terminal disease of renal
dysplasia.
It soon became apparent that there had been many
years of denial within our breed with regards to its existence, and
also varying degrees of suppression of information surrounded some
affected litters. However with my ability
to research and obtain information, coupled with my complete
inability to be intimidated by anyone, including well known breeders
and leading personalities within our breed, I soldered on.
As I gained clearer information about the disease,
most of which came from other affected breeds, I circulated this
information by email throughout the GSD fraternity within the UK,
and on occasions outside of the UK also. I was informing, raising
awareness, and on a fishing trip. I was, as expected, NOT inundated
with responses, but those responses I did get were very useful and
gave me leads to various avenues of research to explore.
After some 100+ hours of internet research, and
various phone calls, I made a major breakthrough. I discovered that
a Genetic DNA test for canine JRD had been developed in Canada,
apparently late in 2007. This test was apparently developed for the
Lhasa Apso dog breed, but is now used to test many more canine
breeds. The test is done by DOGenes canine DNA services of Canada.
DNA TEST FOR JRD
This DNA test (a swab of the gums) can identify
whether a dog (male or female) is affected, a carrier, or free of
the JRD disease. The normal charge for this DNA test is between 70
US$ and 155US$ per test. I am pleased to report that I have been
offered some DNA tests for JRD free of charge by DOGenes Inc. of
Canada, and they will send me the test swab kits also free of
charge. There will obviously be postal charges.
I would like to send swabs for analysis with this DNA
test from a range of GSD, for example:
1) Sire and/or dam of affected litters
2) surviving puppies from affected litters
3) affected GSD
I may also be able to include swab samples from
litters which the breeder is seriously concerned may develop the
disease. Especially litters from a suspect line.
I have identified two sires
that appear in most, if not ALL cases of JRD that I have identified.
(both Sires are in Busters pedigree) However until these DNA genetic tests are complete, it would be
wrong for me to name them, however there is an urgency to collect
these swab samples and complete the tests, so that breeders can make
informed decisions regarding their future breeding plans, with due
regard to this JRD disease.
I envisage the possibility of GSD who are tested
being identified as either – affected, carrier, or clear.
I am also in contact with Animal Health Trust (AHT)of
Newmarket, with a view to DNA tests for JRD being done by them,
however that may require an agreement with DOGenes Inc. of Canada.
If any GSD breeder or GSD owner in the UK is
interested in one or more of their GSD being included in the free
DNA test for JRD, please contact me, in strict confidence,
and I will then get an idea of the number of tests desired, and see
if I can obtain them all free. I would like to indicate numbers to
DOGenes Inc. within the next 7 days.
