There is no breed of dog that is totally free of
health issues, but the Siberian Husky breed has been very fortunate in
this respect. They are generally healthy and have a good temperament and
throughout the years, there have not been a great amount of genetic
issues.
One of the things that we test for, is hip dysplasia.
To put it simply, this is where the hip bone does not fit into the
socket in the correct way. This is an inheritable condition and is
passed on by a combination of multiple genes. Because of this, it is
possible for a normal dog to produce a certain amount of dysplastic
pups. Although both parents in the breeding pair may be normal, they may
each have some of the multiple genes needed to produce dysplasia. When
their genes combine in breeding, it may be the combination needed to
produce a dysplastic pup. There is as yet, no way to test for this in
normal dogs.
We do OFA test our dogs, which is the test for hip
dysplasia. If one of our dogs would fail this test, it would not be
used for breeding. However, as stated above, even if both parents pass
this test, a dysplastic pup may be produced if each parent has a part of
the multiple gene combination which is needed and they combine in the
pup. The chance of producing a dysplastic pup is lessened by testing,
though.The OFA test helps breeders weed out any dog who is not normal.
Therefore, it is still important to OFA test, so dogs that are shown
to be dysplastic are not used in a breeding program.
While we test for dysplasia, fortunately, it is not a
huge problem in Siberians. According to the Siberian Husky Club, out of
114 breeds of dogs which are at risk for hip dysplasia, the Siberian
Husky is one of the breeds least affected, ranked at #111 out of a
possible 114.
Another possible health issue in the Siberian is
inherited eye defects. There are many types of inherited eye defects,
but only three are considered a concern in the Siberian Husky. These are
hereditary cataracts, also known as jeuvenile cataracts, corneal
dystrophy, and progressive retinol atrophy or PRA. Eye problems in the
Siberian can be serious and should not be overlooked.
Of the three eye concerns, hereditary or jeuvenile
cataracts are the most common. These may be able to be seen in a pup as
young as 3 months of age. They usually will develop by 2 or 3 years old,
if they are going to. They can be mild and cause diminished vision or
they can be so severe that they cause blindness.
Corneal dystrophy affects the cornea, which is the
transparent portion of the eyeball. It results in a hazy opacity in the
cornea.Vision is seldom affected and there is no effective treatment at
this point.
PRA affects the retina of the dog.This is where the
rods and cones of the eye are. Rods are necessary for sight in dim light
or night light and the cones are necessary for vision in bright light.
This condition will first cause a loss of night vision and then day
vision, leading to eventual blindness.
We CERF screen our dogs. Any that have
this screening and do not pass, are not used in a breeding program.
However, it is possible for any dog to pass their CERF test and still be
a carrier. They will display no cataracts or traits of these diseases.
Their eyes will be and will test, "normal" or be found to be "clear' of
cataracts. So CERF or SHOR tests will help you weed out dogs who have or
are getting cataracts, but not dogs who are carriers. There are some
estimates that state that likely 75% of all siberians ARE carriers.
CERF testing does not weed out dogs
who are carriers of the recessive gene for any of these eye issues. If a
carrier dog is bred with another dog who is a carrier, they will produce
a certain number of pups who will get cataracts or PRA, etc. There is no
way to tell if your dog is a carrier. Scientists are working on
developing genetic tests to determine which dogs are carriers. Once that
is accomplished, it may be possible to entirely wipe out these eye
issues in this breed. As it is, with the available testing which allows
us to weed out dogs with cataracts, the incidence of
hereditary cataracts is thought to be at about 8% of all siberians.
About 3% get corneal dystrophy and less than 1% get PRA. So, our present
testing is helping keep the incidence of these eye issues much lower
than they would be with no tests. However, because people do not have to
post failed tests, the incidences of these eye issues are felt to be
much higher than these statistics reflect.
The final issue for this breed is an intestinal
issue. This breed is more prone to irritable bowel syndrome and diarrhea
than many breeds. Beacuse Siberians are so clean about themselves, they
groom themselves much like a cat. This is wonderful, except in doing so,
they ingest alot more bacteria than many breeds. This sits in their
intestinal tract and if they have a strong immune system, it will keep
it in check. The dog won't notice it and neither will you.
However, if they are stressed, it suppresses the
immune system and they can get a flair of some intestinal issue like
coccidia or giardia. Coccidia is a bacterial parasite and giardia is a
protoza. I have read that as many as 70% of all Siberians carry one or
both of these in their intestines,most of the time. Their good bacteria
and their immune system, keep it in check. If their immune system gets
suppressed and they get a flair of one of these, it will bring on
diarrhea. The puppy will play, eat, sleep and act normal in all ways
except for having diarrhea. Your vet can put them on metronidazole for
giardia or albon for coccidia and in about a week, it will clear up.
Changing foods too quickly can also bring on
diarrhea. Even drinking city water as opposed to well water can upset a
new puppy. It is important to make any changes gradually.
There are rare cases of chronic diarhea which most
often can be cured or at least improved, by choosing a better dog food.
It is also good to use a probiotic on the food, with this breed. Do not
feed human food to a Siberian or you no doubt, will have "messes" to
clean up.
All in all, this is a very healthy, hardy breed. They
are energetic, non-aggressive, and have great temperaments! This breed
is blessed to have a minimum of health issues. With good breeding
practices, such as testing, Siberians will continue to do well and be a
sound and healthy choice for a pet.
