The German Shepherd Dog is a very popular breed. In fact, it is
Number One worldwide although in the U.S. it ranks much lower partly
because of AKC clubs’ non-adherence to the international Standards —
usually in the AKC top ten, though. As a result of there being so
many GSDs, veterinarians and others typically see more cases of most
disorders than they do in other breeds. Popularity has its
drawbacks, and undeserved notoriety is one of them. Take the
incidence of dog bites, for example. Many breeds have far more of a
tendency to bite people than does the GSD, although they don’t get
the same “press” (publicity). Min-Pins, Skye Terriers, American
Cockers, Chows, and many others will sink their fangs in you more
readily and with less provocation. But the popularity of Shepherds,
Rottweilers, and a couple others is their downfall.
Of course, not all popular
breeds are involved in as many biting incidents. You have to travel
a long road to find a Golden Retriever that has ever bitten a
person, and Labs have an intermediate incidence compared to others
of its size. Nor do big dogs bite more (although perhaps with more
damage) — the mastino types are usually placid, while the feists
like Chihuahua/terrier-types and mixes give credence to their name
and the word “feisty”.
That was just an example of
generalizations that abound in the dog world. Some are unfounded;
others have a basis in statistical facts. But I want to concentrate
more, in this article, on non-behavioral problems. Another example
of those generalizations is the incidence of hip dysplasia.
Rottweilers and American Pit-Bull Terriers may have nearly the same
percentage and typical severity of HD as in the GSD, but the
Shepherd is somewhat different than most breeds, in that HD causes
more discomfort and lameness than does the same degree of looseness
in the joints of the more stoic breeds (many with some bulldog
heritage).
Another problem seen quite
frequently in the GSD is the deficient immune system syndrome (a
syndrome is a collection of symptoms). It is characteristic of this
problem to manifest itself in one dog in a certain way, and in
another dog in a different way, a little like a pleiotropic trait.
Some evidences are so slight that many owners and vets miss or don’t
guess at the underlying cause. This can lead the doctor to wrongly
prescribe a certain medicine or none at all, and the breeder to go
ahead and breed a covertly defective dog that should not be mated.
Further complicating the matter, and preventing as much progress as
could be had, is the subclinical nature (a lack of, or
hardly-noticeable, signs). Many intermittent or mild complaints that
owners have are not identified as related to the dog’s immune
system, and others have taken years of badgering by breeders before
the veterinary community has acknowledged what breeders had known
all along. So you will find some disagreement in some of what I will
present in the following material. I don’t want to just list a table
of disorders under the subject heading, but you might want to do
that for yourself. Let’s take a look at some of those
immune-mediated disorders after a few more words about the general
subject.
The GSD has more than its
“fair share” of immune-related problems, and the clues usually
appear in the intestines, eyes, skin, and other places. The breed
has many individuals with a deficiency of a particular
immunoglobulin called IgA, and this genetic defect may be very close
on the chromosome to genes controlling general immune problems.
However, we must remember that environmental “events” such as
exposure to certain chemicals, and especially to multi-component and
frequent vaccines, can be and probably is the greatest factor in the
many cases of autoimmune disorders we have seen increase in the GSD
and in many other breeds.
Autoimmune disorders
The dog’s “Defense
Department” has a number of soldiers: antibodies, immunoglobulins,
specialized cells, and more. Some vaccine ingredients, adjuvants, or
carriers have been known to cause an over-reaction by this army and
result in an autoimmune situation in which the body also attacks its
own cells. A recent vaccination development called “recombinant
vaccine”, helps avoid bad reactions to vaccines or the medium in
which they are cultured or carried into the blood system, but is not
effective against parvo. Nowadays, the over-reaction is more often a
matter of the interplay of genetics with stimulus from vaccine
components. The more vaccines that are given to the dog, the more
frequently administered, and the number that are in the same
combined “shot”, means that the part environment plays in reactions
is much larger.
The German
Shepherd Dog breed seems to be at relatively higher risk for a
number of systemic abnormalities, and while not all have been
directly linked to immune suppression, with most of them there is
great suspicion of some connection. We have seen such problems in
the breed as pannus (chronic superficial keratitis), corneal
dystrophies, and plasmacytic conjunctivitis in the eye; lupus and
anal furunculosis in the outer integument; and plasmacytic colitis
in the gastrointestinal tract; these we suspect are related to
autoimmunity. The various components and functions of many glands
and chemicals in the normal body are lumped together to refer to
their joint action of protection, and given the name “immune
response” or “immune system”. It involves such things as T cells,
phagocytes, white blood cells, antibodies (immunoglobulins),
complement proteins, and others. Together, their job is that of a
second line of defense against antigens and other threatening
“foreigners”; the skin, mucous membranes, and stomach acid are some
of the first-line defense mechanisms that bodies have, and if
something harmful gets past the frontline troops, the interior guard
must go to work.
Invading
organisms may be viral, bacterial, parasitic, fungal, and may come
into the body via puncture, swallowed foreign objects, impurities in
eaten material, absorption through the skin, intake by the lungs, or
other routes. This second line of defense even goes after waste
generated in the cells, or abnormal cells which if left alone could
become cancerous. To do this, the soldiers must be able to recognize
the enemy, and do so by chemical means, such as “seeing” if the
projections on the suspects fit like jigsaw pieces into receptors
carried by the troops. If so, they attempt to neutralize by putting
chemical handcuffs or a half-nelson on those invaders until they can
dispose of them. Some of the home guard, macrophages, actually “eat”
bacteria; some poke holes in the invaders or mark them for other
cells to eat or destroy. When such interactions occur, the guard is
stimulated to call for reinforcements (multiply rapidly) to search
for more of the invaders’ ilk. B-lymphocytes have antibody protein
molecules on their cell surfaces that recognize the foreign molecule
called an antigen. One result of this encounter is that these B
“white blood cells” become antibody factories called plasma cells,
and can turn out their product for many years to come. Thus, some
diseases are warded off the rest of our lives because our bodies
continue to have patrolling soldiers that can recognize them. The
other type of defender lymphocyte is the T cell. They directly kill
“bad” cells without using antibodies. Besides killer T cells there
are helper T cells and suppressor T cells; the latter call off the
attack so the white blood cells (lymphocytes) don’t get carried away
over-multiplying (hopefully!) or that would present other problems.
One hitch in the war
machinery is that some lymphocytes get confused and mistake normal
body (called “self”) proteins for the “bad guys”. If “self”
doesn’t kill off these errant traitors, as normally happens in the
embryo and very young individual, we have what is called an
“autoimmune” situation. An oversimplification would be to say that
the body is “allergic to itself”. In any case, the body uses the
home guard to attack and possibly destroy part of itself (its
self). Such a defect can affect immune response all through the
body. It is possible that this is happening in pannus, “allergies”,
lick granuloma, and a number of other problems in our dogs. In human
AIDS, all the active helper T cells are destroyed, so the body no
longer has adequate defenses against any and all antigens. In most
disorders, only one or two pathways are affected, so a problem may
show up as an itch, skin blisters, hemolytic anemia, a corneal
defect, rheumatoid arthritis, or something else in one or more
organs.
Demodex
— One of the most easily identified immune-mediated problems is
demodectic mange. To distinguish between this and the purely
contagious sarcoptic mange, see some of my other articles or buy my
book on the GSD. The demodex mite is ever-present on nearly all dogs
and humans, but doesn’t cause a problem unless the host is weakened
by something, especially another immune system related disease or
stress. It is widely believed that stress of various kinds, whether
of a genetic origin such as a very nervous temperament, or either a
genetic or acquired immunodeficiency disease that suppresses T‑cell
function in the immune defense system, may be the major factor in an
outbreak of symptoms such as demodecosis in a dog. With lowered
cell‑mediated immunity, the individual reacts adversely not only to
the mite and its toxins, but also to the presence of other microbes
and antigens.
“Neutering” reduces stress
in the individual (as well as putting the brakes on the spread in
the gene pool). A bitch in estrus is in the highest state of
systemic stress that any dog normally encounters, outside of severe
trauma and shock, so spaying is recommended in cases of demodex.
Often enough, demodecosis is concurrent with another immune-related
defect. If your dog has demodectic mange, look for another condition
that should be treated at the same time. Is there a history of
subclinical pancreatitis? Has there been recent surgery or other
physical or emotional trauma? Any exposure to debilitating diseases?
Even the minor stress of teething may be sufficient to tip the
balance and encourage sudden proliferation of demodex mites and
their symptoms in susceptible “on the borderline” dogs. Very healthy
dogs rarely show symptoms even when exposed intentionally by
clinical transmission of these mites. Stress (such as illness) seems
to "awaken" the mites. Combating demodecosis is largely a matter of
curing or controlling the dog's other ills, both physical and
psychological. Use of steroids is contraindicated because they
compromise the dog’s immune defense. See my “Total German Shepherd
Dog” book for more detail on this topic.
Pancreatitis:
In its chronic, subclinical, or often-undiagnosed mode, exocrine
pancreatic insufficiency (EPI or PI) is fairly common in German
Shepherd Dogs of certain bloodlines. It has even been identified
with demodectic mange, possibly because during the stress of the
dog’s affected digestion, its body is less able to immunologically
suppress the proliferation of the mange mites. Supplementation with
vitamin A and pancreatic enzymes should be supervised by a
veterinarian who is knowledgeable in this area and has been made
aware of the genetic portion of the problem in certain lines of our
breed. The occurrence in pancreatic insufficiency among German-line
dogs in the U.S. seems to have increased since the 1970s, but I
believe there are a couple of different reasons for this, if it is
an accurate observation.
Malabsorption (poor digestion and poor stool condition) are
frequently seen in the GSD, and in my experience, has been more so
in the heavily linebred typical lines in American-bred dogs since
the 1970s. EPI is one of the conditions
that can contribute to the malabsorption syndrome.
The symptoms can be exacerbated by
physical or emotional stress, change of food, and other things. I
suspect that dogs with subclinical weakness in immune systems or
pancreatic function may be most likely to show these reactions. I
have also seen an apparent connection with temperament weakness, as
those dogs with especially “hard” character have a much lower
incidence, and there is a higher percentage of digestive disorders
among American-line GSDs which customarily are not trained in,
tested for, and eliminated by the Schutzhund (protection) sport.
With EPI, the fur often
becomes dry and brittle, and even lost to some extent, and
Staphylococcus infection scabs may appear on the skin because the
compromised immune system doesn’t allow the dog to fight off the
infection. The symptoms of EPI mostly show up when the TLi value is
down (Trypsin‑like immunoreactivity test). So there seems to be a
possible connection, with insufficient pancreatic function and other
“resistance” all being tied to the immune system.
A dog with the sub-acute
form of pancreatitis may exhibit coprophagy, which means he eats his
own (or others') stools. It may be that he smells the undigested
fats and carbohydrates and instinctively consumes it as food to give
those nutrients "another chance." Remember, though, this can also be
a habit arising from boredom, lack of owner clean-up, or diet.
Often, the addition of liver to a low‑fat diet and daily
administration of enzyme powder or capsules, or regular
supplementation with ground or chopped pancreas if you are lucky
enough to get some from a nearby slaughterhouse, will bring the
condition under control or at least improve it. Researchers at
Tulane University found that a commercially available enzyme
supplement could improve blood analysis, neonatal vitality,
digestion, and general health. The manufacturers of Viokase™, one
dried raw pancreatic enzyme brand, have shown supplements/medicine
to be effective in combating nonspecific diarrhea as well as
subclinical pancreatitis. The juvenile-onset generalized demodecosis
often has a spontaneous semi-remission because of better stress
management.
Dogs that exhibit symptoms
such as much flatulence, or intermittent diarrhea or pasty
light-brown/yellow to clay-colored stool, perhaps should be tested
for levels of Lipase, Protease and Amylase, or just fed the
recommended preparations without testing. But keep an eye out for
other immune-system signs, too. Some people perceive a probable
connection or coincidence between anal furunculosis (perianal
fistulas) and EPI. Both of these problems may show up in the same
dog, strengthening the suspicion that they are manifestations of the
same underlying immune system weakness. A great deal of the
digestive tract functions and stages may be affected one way or
another by the same genes governing immune response.
Pancreatic insufficiency is
an abnormality that suggests removal from the gene pool, whether the
dog has a severe or a mild case or is asymptomatic most of the time.
Most vets take very few hours of nutrition and practical genetics
classes in vet school, and then forget most of it because they don’t
use it every day. Breeders are sometimes more reliable sources of
information.
Unfortunately, many people who offer their EPI males at stud do not
admit or declare any cautions about their dogs. As one observer
quipped, “It’s funny isn’t it, that those who deny all those things
have Viokase-V on the shelf in their back rooms?” Although it is
good for various unspecified causes of diarrhea, the product is so
much more expensive than kaolin or changing the diet, that it makes
you wonder if you should try one of the other “remedies” first.
Bloat/Torsion/Volvulus:
Is there a connection between PI
and GDV (gastric dilation and volvulus)? There have been reports
from dog owners indicating that many episodes of EPI begin with a
bloating incident, or with gastroenteritis, marked by vomiting and
blood tinged diarrhea. One observer said, “From
the general info collected, the dog first bloats, which often leads
to torsion of the gut, which of course requires surgery for a
tacking of the stomach, and this is usually followed by a full blown
episode of EPI within a few months of the surgery.” I suspect that
there is, at least sometimes, a common root cause if these two
problems. Dogs with a history of bloating/torsion
and/or bouts of unexplained diarrhea are reported by several of my
correspondents to be quite likely to be EPI-carrier suspects,
although this observation is admittedly anecdotal.
Megaesophagus:
German Shepherds have over thirteen times the incidence of
esophageal disorders of all other breeds combined, although PRAA, an
unrelated heart defect that causes similar symptoms as caused may be
part of this statistic. Dr. Labato at Tufts U. School of Veterinary
Medicine says, “It [sometimes] may be secondary to … myasthenia
gravis, systemic lupus erythematosus (SLE is an immune‑mediated
disease), …[and possibly others].” Breeds susceptible to the
juvenile-onset, inherited type of megaesophagus include Irish
Setters, German Shepherd Dogs, and a few others. Frequently, large
dogs are diagnosed with the idiopathic form, which means the cause
is unknown. “In most cases we don't know the causes”, said Dr. Twedt
in the vet school at Colorado State University.
The characteristic loss of
peristaltic action is probably due to a disorder of the afferent
nerves, which is why there is no successful medical, pharmaceutical,
or surgical treatment. There may be a connection with other nerve
disorders, even giant axonal neuropathy, which mimics HD and GSD
myelopathy. Because of these similarities, some have hinted that a
general immune system deficiency is at the root of this problem, as
it appears to be in so many disorders.
Diagnosis of megaesophagus
is confirmed by means of various tests, some of which are intended
to discover the underlying cause, and may include the acetylcholine
receptor antibody titer that is used to diagnose myasthenia gravis.
An antibody titer is a blood test that looks for immune-mediated
disease — one in which the body attacks itself. One source I detail
in my GSD book states that the incidence of symptomatic
mega-esophagus in the GSD population in the US is at least 1%, but
about 18% of U.S. (AKC-lines) GSDs are carriers of the altered gene
(assuming autosomal-recessive inheritance). With 18%, the [risk],
even if you avoid linebreeding and stay completely away from all the
[known] lines, is extremely high. The pedigree study in “The Total
German Shepherd Dog” (published by Hoflin) indicates that both Bernd
Kallengarten and Lance of Fran-Jo were suspects in carrying the
recessive for megaesophagus, and the latter was known to produce a
considerable number of descendants with various other manifestations
of immune defects.
Intussusception:
In very young pups (and other animals
including humans) the intestine can invaginate (one part slips
inside another). The condition, also referred to as “telescoping
intestines”, also occurs in adults, but not as frequently. Most
common immediate causes include worms, obstruction by indigestible
materials, garbage, or toxic substances. However, since the German
Shepherd Dog seems to experience a relatively high incidence of this
disorder, I have to suspect the possibility that (other than those
above causes) there is a genetic propensity in certain bloodlines,
and perhaps interrelated to other “GSD disorders” — those more
common to this breed than most others.
Pannus:
The GSD has more than its “fair share” of immune-related problems,
and they appear in the intestines, eyes, skin, and other places.
The breed has many individuals with a deficiency of a particular
immunoglobulin called IgA, and this genetic defect may be very close
on the chromosome to genes controlling general immune problems. The
GSD, after the West Highland White Terrier, probably also presents
most of the cases of pannus, an eye disorder caused by lymphocytes
migrating into the cornea and causing blindness unless treated. More
and more vets are referring to it as chronic superficial keratitis;
CSK for those addicted to abbreviations. I have watched quite a few
eyeballs “peeled” in the surgical part of the therapy, in the days
when steroid drops in the eye on a frequent basis (several times a
day) for the rest of the dog’s life was the post-surgical treatment
of choice. Peeling was the more heroic procedure, when injection of
cortisone under the conjunctiva as a first step is not effective.
Today the drug cyclosporine is used to best advantage in pannus,
although a steroid such as dexamethasone is still effective. This
cyclosporine is the same drug, originally found as a component of a
Norwegian soil fungus, that is given to counteract the body’s
tendency to reject donor organ transplants. The drug is given as an
ointment or in food twice a day until the cornea is free of the
lymphocytes, then there is a once-daily administration; it seems to
work partly by causing the tear ducts to operate almost full time.
Enough is absorbed by the tissues of the eye to get into the far
reaches of the circulatory system where it does the other part of
its job, fighting those wayward lymphocytes. Tacrolimus is 10 times
as potent as cyclosporine but is minimally absorbed through the
skin.
No cure is in
sight, since it is highly likely that pannus is an inherited
autoimmune disorder, and people who have dogs with pannus will have
to deal with the frustration and regimentation of daily treatment
for the dog’s lifetime. The same situation has been nagging
sufferers from human autoimmune disorders for a long time. MS,
multiple sclerosis, is considered by most to be such a disease, in
which T-cells attack components of the central nervous system
(brain, spinal cord and some major nerves). One of those components,
myelin basic protein (MBP) has been experimentally fed to lab
animals, and later to human MS patients, and it was discovered that
the severity of symptoms was considerably reduced. Rheumatoid
arthritis, dealt with more in my book on orthopedic disorders, is
another supposed autoimmune pathology in which the T-cells act
against parts of the joints, especially Type-II collagen. Again,
oral-dietary administration of this type of collagen was fed to RA
patients with significant improvement in managing the disease
symptoms such as number and severity of swollen joints, gripping
strength in the hands, and subjective descriptions of pain or
stiffness after rest or sleep. Experimental treatments involving
feeding normal cornea extracts to dogs with pannus may have similar
results.
Pannus was
previously called “keratitis superficialis vasculosa pannosa
pigmentosa chronica”, “German Shepherd Dog Keratitis”, and
“Keratitis Überreiter” after its Austrian discoverer, is an
inflammation and pigmentation of the cornea and sometimes involves
the conjunctiva. It is rare in almost every other breed, and in the
GSD it usually appears around 3-5 years of age and in both eyes. By
that time, many affected dogs will have already been bred. Besides
the hereditary, breed-dependent predisposition there is an
environmental component that brings it on earlier and more
certainly: ultraviolet radiation. UV rays in sunlight trigger the
onset of symptoms, explaining why an increased incidence is observed
anywhere during the sunnier months of the year, and more cases are
presented in higher elevations such as Denver. This means that to
avoid outbreaks of the acute phase, the owner should not only keep
up with the medication schedule, but also make sure his dog is
protected from exposure to strong sunlight, even if reflected off
snow or water, and especially at high altitudes. Some dogs are kept
indoors (glass windows filter out most UV rays) and are walked in
darker hours; some wear fitted sunglasses.
Corneal dystrophy:
While I do not draw any definite connecting lines between pannus and
this disorder, I mention it because I think there may be an immune
system relationship here, also. Small opacities may appear on the
cornea over the pupil or slightly off-center, and the novice might
think the dog has cataracts. It may be triggered by an allergic
reaction or some other suspected cause, and show up as a small spot,
varying from slightly translucent to cloudy-white. The size is
usually less than 5mm across, round, oval, or horseshoe-shaped.
Most eye specialists refer to this type of opacity as "corneal
dystrophy"; the spots do not interfere with vision. In my experience
the spots have faded away in a few years after reaching maximum
size. Corneal dystrophy appears to be genetic, but is not serious.
Probably less than one percent of the breed is affected. I once had
a bitch who developed very small oval opacities, one on each cornea,
after she was about four or five years old. They finally and
gradually disappeared (shrunk to nothingness) by the time she was
about ten years or more. This bitch also developed atopic
(allergic-type) problems marked by itching feet and sometimes parts
of the skin, but most noticeably by an assumed feeling of excess
phlegm in the throat. One of her many sons developed the same
transient and minor corneal defects, appearing in maturity and going
away without treatment by old age. While it is possible that some of
these opacities may be immune system related, I think most are
largely if not fully environmental.
Pemphigus:
Uncommonly seen in dogs and more found in humans, this group of
related autoimmune disorders involves mostly the mucous membranes
and skin. You may never notice the spider-web mucosal condition in
the mouth or purplish, fragile splotches of skin in some forms. In
some forms it can produce ulcers in mucous membranes. Very high
doses of corticosteroids for life may control the disease,
but this is a controversial approach because steroids are generally
contraindicated in autoimmune diseases, and usually cause a great
deal of capillary rupture and bleeding. It may be best to just leave
these alone and see if they will “go away” on their own.
Primary Seborrhea:
I strongly suspect seborrhea may sometimes be a sign of an acquired
autoimmune disorder. I would bet on it. This disorder is a condition
in which there are scaly patches and a greasy feel to parts of the
dog’s skin. You will probably notice great difficulty in keeping the
ears clean and free of dark wax and yeast or fungus. Often, the
older, long-affected dog will have an over-all rancid odor. Many of
these cases are related to thyroid hormone imbalance, and such an
immune- and general endocrine-related disturbance may become chronic
and in need of very frequent bathing and/or ear cleaning with little
or no hope of remission. Soloxine (thyroxine, or levothyroxine)
might be indicated and recommended by your veterinarian. It would
not hurt to try, as this drug has very few minor side-effects. The
disease most probably is centered in the thyroid.
I have seen many cases that
have been brought on (triggered) after extended or repeated exposure
to fleas and other factors. The flea allergy or exposure may be the
prime cause of the skin condition, with the flea antigens weakening
the dog’s immune response and thyroid function, resulting in severe
seborrhea. Or, the immune defense weakness may be the prime cause of
the dog not being able to withstand fleas. Ask a veterinary
dermatologist to try to find the underlying cause as well as give
you ideas on how to treat for the symptoms. If the dog shows
evidence of much itching, it is usually called secondary seborrhea,
which refers to a primary cause being mange, fleabite allergy, or
other trigger influences, involves relatively large reddish-skin
patches with hair loss, and is often more scaly and less greasy than
is the primary form. Primary seborrhea is something GSDs seem to be
more predisposed to than are most other breeds, and it is this type
that more affects the ear with fungus growth, and sometimes an
increase in bacterial colonies on the skin. It is a chronic
condition that requires constant or renewed treatment regimens with
no hope of eventual cure, just some control.
Most owners of dogs so
affected report considerable success in managing or partially
suppressing the symptoms by attacking them on several fronts: get
rid of fleas (and the cats and carpets they rode in on!), clean the
ears daily or several times a week with a 50/50 mix of vinegar and
water, and temporary regimens of Soloxine for perhaps two weeks
initially. Your vet can suggest a dosage level to try, of this quite
safe internal medication, and by adjusting the dosage, you can find
an acceptable maintenance level.
Degenerative Myelopathy: DM was once as “GSD myelopathy”
because most cases in the early days of investigation involved this
breed. It is the first disorder that comes to mind when German
Shepherd Dogs and spinal lesions are spoken of together.
“Degenerative” means that it is chronic and progressive, and
“Myelopathy” means spinal cord disease. The first symptoms are
usually seen at about six to eight years of age and have a duration
of five to twenty-four months, perhaps a bit longer if aggressive
measures are taken, but who knows if they are really effective?
Initially, the dog does not seem to realize what position his rear
legs are in; soon he will begin to drag his toenails and the top
part of his paws, and later may tremble as if palsied. Eventually,
he will be unable to get up on all four legs, and by this time most
owners will have decided upon euthanasia. Symptoms and histological
changes are very similar to those in multiple sclerosis (MS).
It is also seen (though
rarely) in the Belgian Shepherd and the Old English Sheepdog, and
some authorities feel that other breeds’ degenerative myelopathies
are probably not caused by the same immune-system deficiency as we
have in the GSD. Autopsy shows demyelination (loss of the insulating
sheath) of the spinal cord, destruction of some large axons (nerve
cells leading from the cord to smaller branch nerves), and abnormal
cells (or certain cells in abnormal locations). Similar signs may
be seen in the brain, kidneys, and intestines, giving further hints
of the immune system failure being at the root of this disease.
It may be that relatively
high vitamin E dosages may be helpful, but it is difficult to
compare a particular dog’s disease progression with a “what-if”
situation. We have a good idea that this vitamin is very helpful in
general immune response improvement, so it is natural to assume a
probable direct benefit in this immune-related disease. 800 units (IU)
a day may be enough, although some years ago one researcher claimed
that 2000 IU of vitamin E daily, 500 mg of vitamin C twice a day,
and a high-strength vitamin B complex twice a day was the best
dosage. While his results were not duplicated by others, I mention
it just in case you come across his claim. In DM dogs, low serum and
tissue concentrations of vitamin E have been observed. I recommend
that vitamin E be given to all older German Shepherd Dogs for
general resistance and health. It can’t hurt — they will excrete
anything they don’t need, within reason — and it is synergistic with
other vitamins and nutrients. Chemical-pharmacological treatment has
largely been via the use of aminocaproic acid, and more recently,
acetylcysteine three times a day found some acceptance, although
conventional drug therapy (medicines) has been of little lasting
help to patients with DM. The combination of exercise, vitamins and
certain drugs seem to have delayed the progression of DM in many
dogs a little. Treatment has been directed at suppression of
symptoms and the multi-pronged approach may slightly prolong the day
you have to face euthanasia because of debilitation and inability to
stand to defecate or to walk.
Lick Granulomas:
Dogs with GSD myelopathy often develop lick granulomas on the
extremities, especially the hind feet; these are non-healing
ulcerations or, if you are lucky, merely callous-like reactions of
the skin to extremely frequent licking, sometimes chewing, at the
location of a supposed itch. It is probably a case of the limb
feeling as if it has “fallen asleep”, to put it into terms familiar
to human experience. The tingling sensation caused by incomplete and
erroneous signals by the nerves serving that place is much like the
irritation caused by an ant bite, or hairs out of place, or anything
in between. In trying to lick it away, the dog actually softens and
wears away the hair and skin. Lick granulomas are not restricted to
dogs with DM, but often occur on the pasterns or toes in dogs that
have atopic allergies, another clue to the presence of a general
immune system deficiency.
Other
problems: Keep in mind that the various parts and systems of
the body are all inter-related, that a disruption in the process of
one may have an origin or an effect in another. The endocrine system
is a prime example, with hormones being produced in more than one
gland and greatly influencing some or all of the other glands.
Something that has not yet been thoroughly explored in veterinary
schools or with research grants is the collection and inter-relation
of problems very common to GSDs, with yeast/fungal infections, flea
saliva allergens, and general autoimmune system weakness. I have
observed countless cases of dogs in this breed with a combination of
seborrhea, low resistance to fleas, thyroid insufficiency, nagging
ear infections, interdigital pyoderma, and other “complaints”. The
lines between these dots, I hope, will someday be drawn with more
clarity.
More about
Vaccines: There is good
reason to suspect over-vaccination to be a big contributing factor,
if not possibly the sole reason for what many believe to be a rise
in incidence of auto-immune disorders.
Kris Christine of The
Rabies Challenge Fund says, “Please
educate yourself to make sure you don’t needlessly over-vaccinate
your companion animals.” She

of over-vaccinating a pet (i.e., injecting it too often, or using
vaccines that are not required for the specific pet)?” he replied, “Yes.
Vaccines should not be given needlessly, as they may cause adverse
reactions. Vaccines are medical products that should be tailored to
the needs of the individual animal.”
My personal
experience as a breeder, show handler, and judge, and other
observation of thousands of dogs belonging to others have convinced
me that there is an extremely high probability of cause-and-effect
between the plethora of vaccinations and inoculations and the rise
in autoimmune disorders I have witnessed in seven decades of living
and working with dogs. I am a scientist, and based on cautious
conclusions following careful observations, I believe that most of
the immune system disorders I have described above result largely
from too many vaccines, too many at once, and too often given.
Other Articles
about Vaccines:
There is a good
article written by
Melissa Burden for
the general pet-owning public, “Are Our Pets Being Over-Vaccinated?” on
http://www.thedogplace.org/Projects/VACCINES/Dodds.Vaccines_Protocol-0606.htm
and
http://www.presspublications.com/pages/specialreports10.asp,
The Press,
June 16, 2006. And in the
July 31, 2002 Wall Street Journal, reporter
Rhonda Rundle in an article entitled Annual Pet Vaccinations may
be Unnecessary, Fatal quoted Dr. Ronald Schultz as saying, “My
own pets are vaccinated once or twice as pups and kittens, then
never again except for rabies.” Dr. Schultz knows something the
pet-owning public doesn’t – he knows there’s no benefit in
over-vaccinating animals because immunity is not enhanced, but the
risk of harmful adverse reactions is increased. He knows that most
core veterinary vaccines are protective for at least seven years, if
not for life.
Other
scientists have come around to realizing the truth in what Schultz
and a handful of others have discovered. The first entry under
Appendix 2 of the AAHA Guidelines in 2003, “Important
Vaccination Do’s and Don’ts” is “Do not vaccinate needlessly – don’t
revaccinate more often than is needed, and only with the vaccines
that prevent diseases for which that animal is at risk.” The website
URL is
http://www.dogs4sale.com.au/AAHA_Special_Report.htm .
They
also caution veterinarians: “Do not assume that vaccines cannot harm
a patient – vaccines are potent medically active agents and have the
very real potential of producing adverse events.”
Very few pet owners have had this disclosed to them.
The AVMA’s Principles of Vaccination now states
that “Unnecessary stimulation of the immune system does not result
in enhanced disease resistance, and may increase the risk of adverse
post-vaccination events.”
Backing up this
statement, practitioners and scientists like Larry Glickman suggest
that the repeated use of vaccines encourage antibodies that can
attack a host’s own organs, causing autoimmune disease.
On page 16 of the
2003 AAHA Guidelines
under
Immunological Factors Determining Vaccine Safety, a comment on
multivalent vaccines states that: “Although
increasing the number of components in a vaccine may be more
convenient for the practitioner or owner, the likelihood for adverse
effects may increase. Also, interference can occur among the
components. Care must be taken not to administer a product
containing too many vaccines simultaneously if adverse events are to
be avoided and optimal immune responses are sought.”
