Hernias in the Imperial Shih Tzu
HERNIAS IN
SHIH TZU PUPPIES as well as other breeds is
very common, and is not a medical condition
or cause for immediate concern. Please be
informed before you agree to surgical hernia
repair on your SHIH TZU PUPPY.
The following information is copied from
Bullwrinkle.com and is being offered as an
educational tool:
"A hernia is a protrusion or bulge of a part
of the body tissue, fat, or an organ through
an abnormal opening of the surrounding
tissue. There are numerous types of hernias,
each type named after its affected area.
A hernia which can be pushed back into the
abdomen is called reducible. Hernias which
are not reducible are called incarcerated.
If the blood supply to an incarcerated
hernia is pinched off, the hernia becomes
strangulated. A strangulated hernia is an
emergency situation and must be brought to
the attention of your veterinarian."
The most common types of hernias in shih tzu
puppies are:
"An umbilical hernia is the most common type
of hernia found in puppies. In case of
umbilical hernias, a portion of fat or
internal organs protrudes through an
incompletely closed umbilical ring.
Umbilical hernias may be present at birth,
or may be acquired. The most common means of
acquiring an umbilical hernia is a result of
the umbilical cord being severed too close
to the abdominal wall. In most cases
umbilical hernias are small and reduce as
the puppy grows. Generally, by the time the
pup is six months old, the umbilical hernia
will shrink and disappear on its own. "
"An inguinal hernia is the result of
abdominal organs, fat or tissue protruding
through the inguinal ring. Inguinal hernias
are presented as skin-covered bulges in the
groin. They can be bi-lateral, involving
both sides or unilateral, involving only one
side. Inguinal hernias are more common in
females than males, but do occur in both
sexes. As with umbilical hernias, most
inguinal hernias will shrink and disappear
as the puppy grows."
Open
Fontanels
Some puppies
are born with what is called, "open
fontanels". The fontanel is the location on
the skull where all of the skull plates
join. It is the "soft spot" at the
top-center of a baby's head. When babies
(human and dog) are born the bony plates of
the skull a somewhat soft and separated. As
the puppy grows these bones will become more
rigid and will gradually fuse together. It
will take 2 to 3 months for the skull plates
to fuse and the soft spot (fontanel) to
close. In some pups the fontanel never
closes. This means that the owner has to be
particularly aware as to the sensitivity of
this area. It should be noted that even
though the fontanel never closes, the
affected pup can still live a full,
energetic and active life. The major
difficulty with owning a dog with an open
fontanel is for the owner - the constant
concern that the spot will be damaged. The
dog is unaware that there is a problem and
will be as rambunctious as any "normal" dog.
It is
important to note that while many Imperial
puppies are born without an open fontanelle,
there are probably just as many born with
one, and its presence is nothing to become
alarmed over. An open fontanel in an
Imperial Shih Tzu will occur on the top of
the head and may vary in shape and size when
present.
Unfortunately, many lay people (and some
Veterinarians not familiar with the Imperial
Shih Tzu) have tried to link the mere
presence of an open fontanelle with the
condition known as hydrocephalus. This has
caused many new comers to the breed serious
concern and undo worry. The truth is that a
domed head with a soft spot present does not
predispose the Imperial Shih Tzu to this
condition.
Along with the observations of devoted
breeders over the years, there is adequate
medical evidence to support this statement:
In "Diseases of the Brain"(1989), Green &
Braund stated that many clinically normal
toy breeds may have open fontanelles without
associated hydrocephalus. *
Drs. Walters and Rivers, Veterinarians at
the University of Minnesota, concluded that
there did not appear to be any relationship
between the presence or size of a fontanelle
and the condition of hydrocephalus. *
Dr.
Alexander de Lahunta of Cornell University
in New York, one of the top neurologist in
this country, stated that it would be wrong
to conclude that any opening is abnormal.
While it
would be impossible to list all the medical
documentation in this paper, these few
included here are perfectly clear: the
presence of a shot spot does not mean the
dog has a medical problem.
The Imperial
Shih Tzu is a little dog! They belong in the
house, at their owner's side, returning all
the love they deserve to receive. With or
without a soft spot, the healthy Imperial
that is loved and given proper Veterinary
care will live well into its teens as a
beloved member of the family.
