HIP DYSPLASIA... . . .AND THE “LMX” PROGRAM
Reprinted with permission from
the Shiloh Shepherds (Kennel) 1986-87 Stockbook
For the past 20
years I have read and researched everything I could find on the subject
of hip dysplasia. I have also written many articles for various
magazines. I would like to reprint the article I wrote in the winter
1983-84 issue of the German Shepherd Quarterly:
Hip Dysplasia

SINCE I have received
so many calls and letters related to my Hip Dysplasia article in a
recent flyer, I would like to make a few clarifications here. Most of
the concern was related to the fact that “if HD is a hereditary problem,
why did you state it was 75% environmental?” HD is a problem that can be
caused by genetics or a combination of genetics and environment. I did
state that the problem was polygenic (controlled by many genes) and that
it has irregular penetrance. That information came from several sources,
including an article written by Dr. J. Giardina, D.V.M. for the
German Shepherd Dog Review, March ‘83 issue. This does NOT
mean we should ignore the genetic factor! If we are to deal with this
problem realistically, we must have an understanding of the total
picture. Everything I have read on the subject of HD always mentions
that over-nutrition during the critical growth period increases
incidence and severity of the problem! This does not mean that you can
breed two very dysplastic dogs, then starve the pups and you’ll have
good hips! If there was just one answer to the problem, we would have
solved it years ago.
Also, I would like to
point out another very overlooked fact! If you can “break down” the hips
environmentally, then you can also “cover up” weaker hips that way too!
Unintentionally! I know of one breeder that had a runt female pup that
she hand-reared from birth. This pup had pneumonia at 5 weeks, then
fought respiratory infections, etc. She was small and sickly looking
until she was 4 or 5 months old. The pup got Eukanuba (30%) dog food and
raw meat (mostly raw meat) plus a lot of vitamin C during that time. At
two years, this pup had an excellent x-ray. None of the littermates,
however, were checked. She was then bred to a very good male, that was
also x-rayed very good, and had 5 pups. All the pups showed severe hip
dysplasia between 6 and 10 months of age. She was then bred to a
champion male (that I have been using for years with excellent results
-- even when inbred on) and again she had 5 pups that were dysplastic
prior to 1 year of age! After checking on her littermates, by then 4 1/2
years old, the x-ray showed severe (grade 4) hip dysplasia. The others
were either dead or we were unable to locate them. We then tried deeper
research by x-raying the bitch’s dam, now almost 7 years old. She also
proved to be very severely dysplastic! She had never been x-rayed prior
to this so there was no way of knowing when the problem had started.
There was also no way to learn the true story on the bitch’s sire, since
he had died at an early age. No records on her sire’s hips were
available. This happened a long time ago, but later the incident would
pop into my mind and I would wonder…What if her sire had been x-rayed,
what would the results show? Needless to say, she was spayed and her
line ended there ... or did it? Two of her littermates had moved out
west and we were unable to locate them. The pedigree was very impressive
so they could have easily been used for breeding, thus passing on the
problem.
Now for the other side
of the coin. A few years ago, I shipped a female pup to a very nice
elderly lady. She wanted a female that would be large and dark colored.
After going over all the stock, she decided on a Max daughter. I
explained that the pup would be dark, very intelligent, obedient, but
not oversized. I told her the pup would mature at about 70 to 75 lbs.
and 24 to 25 inches in height. I felt this pup would work out the best
for her total needs. She was truly impressed with the pup’s
intelligence! Since this pup seemed to inherit that “super smart”
personality from her dam, she was perfect. The only problem was the
weight on this “poor thing” as her owner called her. She weighed only 14
lbs. at 9 weeks when shipped, and her new owner felt that it was just
terrible that she was so thin. She was afraid that the puppy would get
“stunted.” She got rid of that “darn dog food” that the breeder
recommended and fed her ice cream, fish and chips, cakes, pastry (for
weight gain), and this pup just loved her casseroles! This lady was
quite well off, and could easily afford to give her beloved pet the best
of everything! She saw to it that the pup got as much to eat as she
could possibly want! She really loved that pup and sent me progress
reports every few months. The first telling me that finally the crisis
was over. Her little girl was now five months old, smart as a whip, 18”
tall and weighed over 60 lbs. She went on to tell me how she loved her
cooking and would eat anything! She slept on the bed, and lived a life
of leisure. No work for this girl, only eat, sleep, and be happy. She
was such an obedient dog, she didn’t need to work. She wasn’t allowed to
swim or do anything hazardous! The next report came at nine months. The
pup was now 94 lbs! What a dog! Only 22” tall but 94 lbs. Her owner was
sure I goofed on my prediction, since the pup was way over already, and
growing by the minute. Still smart as a whip, but she was showing pain
climbing stairs. I wrote back strongly urging a diet, and a hip x-ray
quick! Well, I got the report back, the vet said grade 2, but it could
get worse. The vet also felt that the pup was at least 30 lbs.
overweight. I really felt bad for all three of us! The poor pup that
would have to suffer, the owner who was totally heartbroken, and I had
to figure out why, how, and what to do next. Replacing a pup is not the
hard part. Trying to figure out how to eliminate the problem, that’s
hard! First I called in x-ray reports on all the littermates, right
away. Ten months may be a little early, but I’m very impatient! The
reports showed all seven of her littermates had good hips so far. I had
x-ray reports back three generations on her dam, and grand dam, etc. I
know there was some genetic weakness there, but the rest didn’t show any
signs of problem and after much checking, I attribute her condition to
environmental influence. Not that the owner didn’t do everything she
could for the dog, it wasn’t a case of negligence, but simply a lack of
education! All that extra food was just too much for
the poor pup. Finally at 14 months, the pup was ‘put down.’ She weighed
128 lbs. by then. Her poor owner suffered those last five months trying
to “diet” the poor pup, but just didn’t have the heart to “starve” her!
Very reluctantly, I shipped her another pup of the same type of
breeding, that somewhat resembled the original dog. But this time, I
insisted on a proper feeding and exercise program. No people food! Not
because “people food” is so terrible, but since this lady had an obvious
problem controlling herself, I felt that a NO order would be more
effective than a “not more than 20% of the dog’s diet to include ...
etc.” realizing that the pup was not allowed anything extra, and afraid
the “worst” would happen again. The owner now followed my full program
to the letter. Results? The new pup is now almost two years old, and her
worries are over. She was measured at 25 1/2” and 82 lbs, and the x-ray
was very good!
Even though it has been
proven that HD is affected by the environmental and nutritional factors
involved in raising a pup, there are many other factors there also! I
honestly believe that if a large enough group of breeders would join
forces together for the benefit of the German Shepherd breed, HD would
be eliminated! I know for a fact there are small breeders that really
love the breed, and really want to do the right thing in their program,
but due to lack of experience and insufficient help from their local
clubs and other breeders, they just end up ‘spinning their wheels.’ Soon
they realize how expensive and frustrating it is to breed these dogs
with all the built-in temperament, hip, and other problems, and they
just give up. These people need education and encouragement, not a
bunch of gossip, backbiting, politics, and false illusions!
I have received many
sincere letters from folks that state, “I have a nice bitch, with
champion bloodlines ... Yup her Great, Great, Grandsire was a Champion’
I am looking for a nice big male pup I can raise up to breed to her ...
how much are they?” Now that’s not funny! There’s people that will
answer and say, “I have a nice Black and Tan male, 8 weeks old for $
etc.” This in turn encourages the owner of the female to purchase the
male, and then breed the bitch, especially if the male has “Champion
Bloodlines” he must be used on their bitch for sure! That’s how the poor
German Shepherd gets all these problems in the first place. Did anybody
ask about the bitch’s pedigree? Did anyone ask about her hip x-ray? What
about the hips of her sire and dam? Does the owner know anything about
her littermates? Have they been x-rayed? Has she been temperament
tested, etc, etc, etc? The breeder of the male pup may have a very good
pup there, but will it do her kennel good if he sires a litter of
dysplastic progeny? Sure, we can blame the poor quality of the bitch,
right? The people who purchased these pups will care. Maybe they will
blame their heartache on the lousy bitch, but they should be blaming
that lousy breeder who sold the pet quality male to the uninformed owner
of that lousy bitch in the first place!
The German Shepherd dog
has been my only breed since I was a child. I have never owned, or had a
desire to own, any other breed of dog. But I do like other animals, and
I attribute some of my genetic knowledge and breeding policies to the
other animals in my life. Have you ever studied the pedigrees of some of
the fastest racing Arab horses in history? They were inbred! Have you
ever talked to breeders of racing pigeons to find out how they developed
the best strains? I’ve owned Arabian horses, Appaloosa horses, pigeons,
various breeds of rabbits, goats, and Persian cats. I have also done
some ‘experimental’ breeding with these animals as well as trying to
learn all I can from the top breeders in each field.
Back in ‘74 I wanted to
‘fool around’ with Persian cats, and ended up learning a lot from their
breeders. As a matter of fact, that’s where I got my idea for the
co-ownership and Breeder’s Agreement policies I’ve used on my dogs ever
since. I realized that cat breeders really ‘hit the nail on the head.’
Not only did they follow a complete controlled program themselves, they
found a way to continue the control in their program after the sale. If
you want to purchase a kitten for a pet, you must sign a neuter or spay
agreement with the breeder. The kitten is then purchased at a reduced
price, but you cannot use it for breeding! They have now made it even
easier for the breeders. The CFA has an agreement right on the papers
that is signed by the new owner, and sent in for registration of the
cat. If you have signed the ‘no breed rights’ agreement, the CPA will
not register kittens produced by that cat. This helps to eliminate the
hassle of ‘holding back papers,’ etc., for the breeder herself. It’s a
very simple program, and of invaluable help to the breeders. They can
sell their pet quality cats without worry of the new owners breeding
these cats to poor specimens, and eventually degrading the breed. I have
just recently purchased a male seal point Himalayan, show quality, with
breeding rights retained. But even so, I would never breed him to any
cat without his breeder’s approval!
We would probably end
up with much better quality dogs if we had similar restrictions in the
German Shepherd breed. I’m not saying that we should discourage people
from breeding GS dogs. I feel that the ‘novice’ potential breeder should
be educated, informed, and somewhat ‘restricted’ as to what they can and
cannot do within the realm of ‘breeding.’ If a slightly faulty dog is
sold as a pet, it should not be used for breeding even if he does have a
Champion somewhere in his pedigree! I would also encourage more breeders
to attempt using the Breeder’s Agreement. When I produce a litter of
pups from an outcross breeding that I’m experimenting with, I sell the
pups for less, and insist on the new owner signing the Breeder’s
Agreement contract. The pup is then tattooed or marked, and the AKC
papers are held back. When the pup has reached maturity and is spayed or
neutered, the AKC papers are then signed over to the new owner. This is
a lot of extra work, but the only way I know of to control future use of
these dogs. When we have excellent quality pups that we want to expand
on, we sell them on co—ownership. This enables us to follow up on an
entire litter, collecting genetic information that is vital to our
breeding program. This also helps us get sincere ‘future breeders’
started off on the right foot with minimum investment and total
supervision of their stock. They will learn as they go, hopefully to
continue producing better dogs. The co-ownerships are also invaluable
for us in the fact that each pup has been put in a different
environmental setting where we can get a much clearer picture of the
inherited genetic factors when matched against the environmental
conditions.
I am fully aware of the
fact that Germany has a lot of sound restrictions built into the
breeding and registering of their dogs, and yet we still see some awful
specimens being imported! Well, nobody’s perfect. Germany does produce
some fantastic dogs, and some very poor ones too. I honestly believe
that the root of this problem stems from finances. Many people have
‘imported in’ what Germany wanted to ‘throw out’ and then proceeded to
breed these imports together for the sake of an ‘all German’ pedigree!
First they breed these ‘culls’ with a fancy pedigree and then they
wonder why they are having all these problems? Has anyone bothered to
really check out the pedigree for quality? Just because a pedigree lists
a bunch of German names, it doesn’t mean it’s any better than a pedigree
that lists a bunch of Champion names. You have to know the dogs you are
working with and take time to research as much as you can about all of
their ancestors, not just a few names you’ve heard of someplace! Also a
lot of people don’t realize that a dog who receives the German “a” stamp
at one year of age could be modestly dysplastic and would definitely not
OFA at 2, not to mention temperaments! I have personally run into so
many brick walls with the German dogs we have in the USA that I can’t
afford to keep at it emotionally or financially. I have just seen too
many small, roach-backed, dysplastic, fear-biting hypochondriacs, and
otherwise disgusting creatures that it makes me want to cry! I’m not
against the German dogs. I am German, born and raised there. I have
lived with real German dogs half of my life. Yet as a breeder, I prefer
to work with stock I can investigate. I want to see the progeny of a
stud before I use him. I want more detailed information on the genetic
qualities bred into the dog, both dominant and recessive. In other
words, I want to be able to check out the entire ‘blueprint’ so I have a
better understanding of what was put into the finished product! Unless I
can investigate at least three generations of ‘input’ behind the dog,
I’m afraid to fool with it. Even with all that caution, breeding
Shepherds can resemble playing with loaded dice! No matter what you do,
you never know when they will explode! I fully understand why it can be
very expensive and discouraging for anyone to stay loyal to this breed!
With all this in mind,
I have designed a pedigree form for our kennel that lists some very
important information on each dog. This will hopefully help the future
breeders get a better understanding of what they are working with. I’m
aware of the fact that it’s definitely not a cure or sure thing, but as
an ‘aid’ in the breeding program, maybe it will help somebody, someday!
These pedigrees are available to anyone that wishes to use them in their
program.
The pedigree starts out
by stating information on the dog itself, and then proceeds to give
vital information on its ancestors.
For a novice who really
wants to breed good dogs, it can be very confusing when they see a
pedigree that states “he’s the daddy” and that’s “Mom,” “Golly Gramps,”
and “Old Granny.” Who the heck are these dogs? Oh yea, we’ve got
Champion So-and-So here, back in the fifth generation, but at least
we’ve heard of him before! So this must be a good dog to breed, but to
what? Well, she’s a bit shy and small, so let’s find a big nasty male to
breed her to, and we’ll have great pups! After all, they are AKC
registered. So they must be good dogs!
Speaking of AKC
registrations, what you see is not always what you get! I’ve heard
stories that would curl your hair. Substitute studs being used, bitches
getting bred again accidentally after the real breeding was done, and
certain ‘dealers’ that had boxes full of various papers that they passed
out with the dogs they picked up at the pound! There is so much ‘paper
play’ going on that it’s ridiculous! But that’s a story all in itself,
and I’m not getting into it here. It’s not the fault of the AKC, they
just register the dogs. They can’t investigate or ‘blood type’ each pup.
It’s definitely a buyer beware market, and if the buyer doesn’t beware,
then the breeder had better!
Now, getting back to
them HIP BONES! Even though we realize that environment has a large role
in ‘showing-up’ or ‘covering-up’ hip problems, we must be aware that it
all roots back to the genetic factor! The environmental factor actually
serves to confuse the picture, making it even harder to plan the genetic
factor. As it stands now, we’ve got a mess on our hands!
Hip Dysplasia does not
always mean that the dog is a hopeless cripple. As a matter of fact, I
personally know of several dysplastic dogs doing Schutzhund work, and
living normal lives. I truly believe that because of this fact we have
such a large problem in our breed. Unless a dog is x-rayed, you may not
even know that he is dysplastic. I’ve had people come to me for stud
service, and when I request the x-ray information on their bitch, they
laugh and say, “Why the way this girl can jump, she couldn’t possibly be
dysplastic!” So I tell them that’s great, but if you want to use my
stud, I want to see a picture of her hips! Just recently a lady got very
angry with me because she did not want to go to the expense. So I
suggested she use my vet since I have established a ‘quantity discount’
rate there. She agreed, and the bitch turned out to be a grade 4! At
eighteen months! We also had a lady recently come from Pennsylvania with
an 8 month old male she was showing, looking for a good compatible bitch
pup she could buy. I suggested she have her male x-rayed before she
purchases a pup to breed to him. She brought the results a month later:
grade 4!
That’s why I insist so
strongly on getting hip reports back on the pups I sell. I need that
information. Without it, I could be taking a wrong turn simply because I
was blinded by
incomplete information! So now let’s add up some of these facts
-
Hip Dysplasia is a
genetic problem, with an irregular rate of inheritance.
-
Even though the genes
may be present, environmental factors can play a large role in covering
them up.
-
Many dysplastic dogs
go totally unnoticed unless x-rays are taken.
-
Many dogs with
excellent hips still produce a large number of dysplastic pups.
The biggest problem in
my opinion is that a lot of people just give up on trying to get rid of
the problem. There are so many genetic and environmental factors
involved that it is very easy to just ‘throw in the towel.’
Please examine the
following quote from the German Shepherd Dog Club of America:
“The
parent club would like to point out that with such a small number of
dogs certified there is real danger in overemphasizing hips in one’s
breeding program. Sound hips are far from being the only consideration
in breeding. The German Shepherd Dog must be regarded as a complete
entity--a working dog, uniquely gifted in intelligence, beauty, and
utility. The breeder should not be swayed by the current emphasis on
hips, to lose sight of the various attributes indispensable to the
German Shepherd Dog; i.e. Sound Character--stability, intellect, and
trainability; correct structure--balance, harmony, and proper
proportion; Gait--ease and efficiency of movement, stamina, and natural
trotting ability; Quality--the reflection of nobility, strength, and
beauty. An exclusive concentration on any one facet may achieve its
effect at the expense of some other attributes.”
My opinion is, the
statement “Sound hips are far from being the only consideration in
breeding” and “There is real danger in overemphasizing hips in one’s
breeding program” actually contradicts the statement that the Shepherd
is a working dog bred for utility! “The breeder should not be swayed by
current emphasis on hips?!” I feel this just opens the door for
incorporating bad hip genes in all the bloodlines! I am fully aware of
the fact that a lot of people will get angry with me all over again, but
there are times when you just have to fight City Hall even if you can’t
win. I have matured enough over the years to ‘get off the bandwagon,’
but I still can’t shut up when I hear that novice breeders are being
encouraged to breed dysplastic, Champion sired bitches for the sake of
‘bloodlines.’ When I hear respected breeders state they will breed their
‘cripple’ bitches to ‘OFA’ studs in hopes of getting at least one good
one; the rest will be sold as pets anyway. If they are lucky enough to
get one good pup and IF he happened to make his degrees, what good is it
if he ends up producing dysplastic pups? No wonder we have such a mess
on our hands! I am fully aware of the fact that there are times we can
run into a very delicate grey area and it’s very hard to decide what to
do in those situations, but I have my ideas on that too.
I realize this may
sound crazy, but let’s take a moment for a fantasy. What if an
organization was formed by a group of dedicated breeders that proceeded
to compile (or program together) all the research done by all the
various groups and organizations, then helped this foundation with their
research by compiling all their knowledge and experience. For example,
the results of breeding bitch A to stud 1 and the same bitch to stud 4,
etc., encouraging all the big and small breeders to participate with
added information. Everybody would submit all they know honestly (this
is no time to advertise) for the benefit of improving the breed! Now the
research center or foundation could enter all this data (tons and tons I
hope) into the most complex computer available. Let’s see what we’ve got
here! Since this is MY fantasy, it would not only be limited to hip
dysplasia, but would include everything! A breeder could then call into
the center and get data on hips, temperament, size, color, conformation,
faults, virtues, etc., along with a full computer ‘fact sheet’
recommending do’s and don’ts for each dog they had. Actually, GSDCA has
a somewhat similar program for their top producing dogs.
Each year you can
purchase a ‘Red Book’ that lists all the ROM studs and broods, along
with futurity/maturity tabulation charts, etc. The listing includes a
picture of the dog, pedigree, and owner’s report that explains a little
about the dog’s personality, etc., along with a list of winning progeny.
The most interesting part is the questionnaire each owner fills out
about the dog. There are a total of 63 questions ranging from eye color
to tail size. The most interesting, of course, is hip dysplasia. I would
sincerely like to commend those breeders that gave honest answers, such
as ‘few,’ ‘some,’ or actually gave the number or percentage of HD
produced by their dog! Some have written “none to my knowledge.” This
could mean several things: the progeny are too young to evaluate yet, or
no x-rays were taken.
My fantasy computer
would contain similar information, but would include and emphasize
specific data such as: Stud’s name, number of bitches bred; number of
puppies produced per litter; number of puppies x-rayed; actual results
(OFA ratings); percentages. For example:
Super Stud; 18 (with
listing of bitches bred); 162 pups, 97 x-rayed, 35 good, 56 fair, 6
moderately dysplastic, 65 not of age; total percent of progeny tested;
percent passed OFA certification. Second Stud; 5 (with listing of
bitches used); 42 pups, 36 x-rayed, 4 good, 2 fair, 12 moderate, 5 grade
2, 13 grade 3-4, 6 NOA. Now with this kind of breakdown, you can get a
much better idea of what you’re doing. Both studs have had some
dysplastics, but which one would you use? What if we expanded this to
include the non-champion dogs such as the German imports, etc.? It is
very impressive to see a Champion with an OFA number, but what if his
title included a ‘status symbol’ such as “Produced 82% OFA certified
progeny?”
If all that just won’t
work, then I have yet another idea! We realize that in America the
emphasis has always been on freedom. We have total freedom to do our own
thing as long as it’s legal. We are proud of the freedom we have in this
country. Anything goes as long as it’s legal. Well then, maybe it should
be illegal to breed dysplastic dogs! Any other suggestions?
