(1) PYOMETRA IN THE BITCH
What is Pyometra?
Pyometra simply means pus in the uterus. (pyo means pus and metra meaning
Uterus). Uterus is the organ in the bitch where puppies grow before their birth.
Pyometra is an abnormal condition where pus gets accumulated in the uterus
leading to a number of clinical symptoms in the bitch. Unless the condition of
pyometra is recognised at an early stage it may end up in disastrous conseque-
nces in the bitch and may even lead to death of the animal.
Age at which pyometra is observed?
Pyometra is usually a disorder which is seen in middle aged bitches of 6-8 years
of age. However pyometra can be seen in bitches as young as 1 year old and the
upper limit can be at any age of the bitch.
What are the symptoms of pyometra?
Symptoms exhibited by the bitch suffering from pyometra depend on the type of the
pyometra. There are two types of pyometra namely open type of pyometra and
closed type of pyometra.
The type of pyometra again depends on whether the mouth of the uterus which is
called cervix is open or not. When the cervix is open the condition of pyometra
will be open type and when it is closed it is of closed type.
How pyometra is caused?
In the bitch following mating or even without mating, but roughly two months after
the standing heat period, a hormone called progesterone increases in the blood
of the bitch manifold its level during the heat period. This increased progestrone
brings about much stimulation of the inside of the uterine bed. There are a number
of glands embedded in the uterus which will secrete a liquid called uterine liquid
as a result of progesterone stimulation. There is increased growth of the inner
layers of the uterus. The muscles of the uterus become weak because of suppre-
ssion of muscular activity of the uterus. This enhances the accumulation of
secretions in the uterus. Bacteria from vagina gain entry into the uterus, multiply
fast in the accumulated secretions and ultimately bring about pus formation in the
uterus.
Stump Pyometra:
Owners who are not interested in using their bitches for breeding purposes often get the animals spayed . Spaying is an operation performed by surgeons in which the ovaries of the bitch are removed. Sometimes while removing the ovaries, both
the ovaries and uterus are removed in which case the operation is called ovario hysterectomy . While removing the uterus a small portion of the body of the uterus is left in the body of the bitch as a stump.If while performing ovario hysterectomy,a small portion of ovaries are left, the bitch continues to come to heat during breeding season. There will be continuous stimulation of uterine stump and utimately if there is infection of the uterus it will lead to stump pyometra. Owners often presume that the seasonal heat symptoms are normal even in a spayed bitch and do not seek veterinary help until some serious symptoms of pyometra like frequent urination, frequent drinking water,
loss of appetite etc. are noticed. It must be remembered here that even some small portions of ovaries are not left behind while performing spaying operation, still stump pyometra may occur
HOW PYOMETRA IS DIAGNOSED BY VETERINARIANS?
1. By studying the history presented by the owner.
2. By physical observation and examination of the bitch for the symptoms
present at time of examination.
3. By Abdominal x-ray- Fluid dense tubular structure is visualised in the
abdominal x-ray. Abdominal x-ray also helps to visualise the presence if
any of the foetal tissue retained from the previous pregnancy.
4. By Ultra Sonography: Ultra sound scanning helps in visualising uterine
size, thickness of the uterine wall, presence of fluid accumulated in the
uterus etc.
6. Blood examination: The white blood cell count may be very high, often
exceeding more than 30,000 per cubic milimetre. There may be evidence
of anaemia.
7. By Urine examination: Specific gravity of urine is altered. There may be
evidence of bloody urine and protein urine.
8. By examination of deeper part of vagina: This is called vaginoscopy, where
in pus may be observed around the cervix or in the most deeper part of
vagina of the bitch. (Anterior most part of the vagina)
What is Treatment for pyometra?
1. Surgical: If the owner is not serious about retaining the breedability of the the
bitch, the veterinary surgeon, performs the operation called ovariohysterectomy
wherein both the ovaries and uterus are removed. If the pyometra is of stump type,
then the surgeon explores by abdominal surgery to locate the presence of any
ovarian tissue and uterine stump and removed them surgicslly.
2. Medical: If the symptoms of pyometra are not severe and if the owner wants
to retain breedability of bitch, the veterinarian may treat the bitch by using a)
higher antibiotics, b) some hormones like estrogens or androgens or oxytocin
c) drugs like quinine or ergot preparations d) of late by using prostaglandins
(still under experimental stage)
Owners responsibility:
Slightest suspicion of pyometra, present the bitch for veterinary examination
and follow his advice.
Some Others Problems In Bitch
(2)Problems Of Vulva
The vulva is the most visible and therefore, readily accessible part of the
female anatomy. The puppy's vulva is normally small and recessed, but
it grows more prominent in the cycling bitch.
Artificial insemination solved Bess' fertility problem. Conformational
abnormalities such Bess' can also be treated with plastic surgery
particularly if they lead to recurrent infections. Careful observation
of litters produced is important to ensure the defect is incidental
and not hereditary.
Obese bitches commonly suffer from a different problem.
As they gain weight, folds of fat develop over and around
the vulva, creating the perfect environment for an infection.
A vital part of their treatment, needless to say, is weight loss.
(3)Problems Of The Vagina
Many of the bitch's reproductive problems involve the vagina.
Vaginitis may seem like a common problem, but primary
vaginitis (no underlying cause) is fairly rare. An important
exception is puppy vaginitis.
More commonly, bacterial vaginitis occurs in adult bitches
secondary to another problem. The signs are similar vulvar
discharge and licking but some detective work can uncover
the underlying cause. Usually the bitch has been treated with
systemic antibiotics for another problem, or in a misguided
attempt to 'sterilize' the vagina. The damages the normal
protective flora (yes, some bacteria actually belong in the
vagina) and allows invasive organisms to overgrow.
Sometimes foreign bodies can cause vaginal infection.
In some parts of the country, grass awn migration
presents a danger for bitches. Their migration into
the vagina produces severe irritation and infection.
Fortunately, the foreign material can usually be identified
and removed with a vaginoscope, a device that lets the
examiner observe the full length of the vagina.
vaginitis is diagnosed by physical examination and
vaginal cytology, which shows white blood cells
engulfing bacteria. A digital vaginal exam is important
to rule out physical abnormalities. In several or
recurrent cases, a vaginosopic exam is indicated.
Ideally, the veterinarian will take a sample for culture
and sentitivity, using a guarded swab to prevent
contamination from external bacteria.
Treatment consists of appropriate systemic antibiotics,
usually prescribed for a two week course. Douching,
or vaginal flushing, is indicated only in rare instances
when large amounts of pus have accumulated.
Vaginal cytology should be rechecked after treatment
to ensure complete resolution.
(4)Tumors Of The Female Reproductive System
Mammary tumors are the most common tumors of the bitch, and are often
hormone dependent. Owners can palpate theirhes' mammary glands to check
for tumors the best prevention is early spaying. (See "keeping a Brood Bitch
Healthy and Happy" for more information.)
Vaginal tumors usually affect older bitches (average age, 11 years). Most are
being and are successfully treated with surgery. The most devastating tumor
is a transitional cell carcinoma, which typically starts in the urethra and spreads
to the vagina. Unfortunately, treatment is rarely possible by the time of diagnosis.
Another type of vaginal tumor is the transmissible venereal tumor (TVT) TVT is
contagious between dogs. It is spread by transmission of whole cancer cells from
one dog to another by breeding or licking of infected areas. Fortunately, TVT is
quite treatable with a course of chemotherapy, resulting in few side effects.
Complete recovery takes from four to six weeks.
Ovarian cancer, although uncommon, occurs more often in older bitches and in
bitches that have never whelped.
Ovarian cancer can be cured by surgery. Once it has spread, however, the
prognosis is poor. Chemotherapy may prolong life in some instances.
The best prevention is to spay bitches when their reproductive careers are finished.
(5)Problems After Whelping
After a normal whelping, it's not unusual to see a green or bloody discharge for a few
days. If a bloody discharge persists, however, and the bitch appears normal, she may
be suffering from subinvolution of placental sites (SIPS). This occurs when the area
of placental attachment fails to return to normal. The reason is unknown, but it occurs
most commonly in young bitches. Recovery is generally spontaneous, although it may
take until the next heat cycle, and recurrence is not common. Rarely, a bitch will lose
enough blood to warrant transfusions or ovariohysterectomy.
Examination is necessary to ensure that the discharge is not due to a more serious
condition-postpartum metritus. This infection most commonly occurs after a difficult
delivery and results in coloured vulvar discharge, fever and an obviously sick bitch.
Immediate treatment with antibiotics and prostaglandin can preserve fertility.
Eclampsia (milk fever) generally ocurs one to four week postpartum-just about
the time most breeders start to relax. When it happens, however, eclampsia is a
true medical emergency.
Two weeks after the whelped, Magic started having severe muscle spasms and
seizures typical of eclampsia. One look at the Cocker Spaniel's six fat puppies
suggested the cause: low blood calcium levels.
Eclampsia occurs when there's more calcium leaving the bitch's body in her milk
than she can replace from her bones and diet. Toy dams an unbalanced diet and
surprisingly calcium supplementation during pregnancy, because it suppresses
the hormone responsible for mobilizing calcium stores from the body.
Eclampsia may be prevented by feeding the pregnant bitch a high-quality diet
without calcium supplementation, and later supplementing puppies from large
litters or Toy dams.
A slow intravenous injection containing calcium returned Magic to normal.
She was then placed on an oral calcium supplement. The pups were supplemented
and started on solid food at 3 week of age. They were lucky; some pups need
to be hand-raised. And some dams don't make it at all.
