...on my
very simple and plain english :-) If you want to read
better writen or else scientific articles about pyometra
just use google :-)
Pyometra
can appear at any age after the bitch has got her first
season. But usually it is more common among older bitches. Hormonal
changes affect to the walls of uterus. After seasons the
hormone called progesterone starts to work and there is
lot of it in body about 8-10 weeks of time. At that time
the walls of uterus grows thicker and prepare for the
possible pregnancy. If bitch will not be pregnant and
years go by the walls will grow thicker and thicker and
there may be seen some cysts as well. Cysts and thick
walls of uterus create an ideal place for bacteria to grow.
But this kind of uterus wall thickening happens every time
the bitch has been in season so that is why even very
young bitches may get pyometra. Also high progesterone
level keeps the uterus big incase of possible pregnancy
and stops uterus to press the pus out of it. Bacteria
can get into uterus via cervix. Normally cervix is closed
but during the seasons it opens to let the semen in. When
it is open also bacteria can get into it and then into
uterus. Some of these bacteria are not normal for the
bitch but can cause problems which lead into infection. The
symptoms of pyometra depend on the cervix - weather it
stays open or else closes up. If it stays open pus can
come out. In these cases pus is seen on bitcheīs coat and
under her tail. It is pale coloured and smells bad. It may
also make the dog bed dirty so it is good to check the
place where bitch sleeps. If cervix is closed pus stays
inside of the uterus and makes it bigger and bigger and in
the end, if the bitch is not treated, the uterus breaks. Infected
uterus has the kind of bacteria in it which releases toxic
poison to the blood circulation. It makes the dog very ill
in very short time. Toxic poison affects to kidneys and
that sometimes makes the bitch thirsty and naturally she
needs to pee more often than usually as well. Other
typical symptoms are fever, depression, diarrea, stomack
upset and bitch may be very tired. Also enlarged stomack
or else unusual bleeding from vulva may tell about
pyometra. But the only way to get the right dignosis is to
take a bitch to a vet and scann her. Also blood and urine
samples are needed. Most
often pyometra is treated by surgery where uterus and
overies are removed. If uterus is only slightly infected
this operation may be just like spaying usually is. But
when uterus is badly infected operation is big and
complicated. If infection is mild also antibiotics may be
used to treat the infection. If bitch is not treated and
she has infection in her uterus she will die. Our
finnish DDT Club made a health survey at year 2004 and
according to it 19 of 77 bitches had got pyometra. In
percents this means 14,6 % so it is about every sixth
bitch who get it. If bitch will not be used into breeding
the spaying will save her from pyometra and it will also
stop the risk of unanted pregnancy. |
