Ok I'm going to address a few things all at once.
Pyometra:
I have never heard or seen this occurring in a pregnant bitch. Pyometra
occurs in diestrus, when the progesterone levels are high (almost always 2
months following estrus), which does coincide with the time of whelp.
However it is a uterine infection that was present at estrus and allowed to
grow
during diestrus due to the high progestrone levels and the closed cervix
(this keeps the infection and the pus trapped in the uterus. Bitches go
through the same hormonal changes with each heat cycle, whether they are bred
or not, so at 63 days post LH surge (ovulation), the cervix opens. In
cases of pyometra the open cervix allows the pus/infection to pour out and
then
the owner becomes aware of the issue. A bitch can get very sick from the
closed infection earlier and the owner may notice she is drinking and
peeing more frequently, not eating, very lethargic, vomiting etc. and the
infection is usually discovered by the vet by bloodwork, xray, and/or
ultrasound. Pyometra is mo
st commonly caused by E. coli. If your bitch carried a litter to term,
but then had a uterine infection it was most likely caused by retained
placentas or an infection introduced during the whelping process as a pus
filled/infected uterus is not able to sustain a pregnancy.
Antibiotic use in breeding bitches or pregnancy:
Be very careful what antibiotics are used in your breeding bitch and
especially during pregnancy. Not all veterinarians are as cautious as they
should be or even know what the side effects of these antibiotics are. The
only "safe" antibiotics to give to a pregnant dog are in the penicillin
family-stick to amoxicillin and clavamox, the rest are just too risky.
I have never heard of doxycycliine causing megaesophagus and can't find a
medical report on any of the veterinary websites, so if there is one out
there, please forward me the information. Doxycycline is known to cause
permanent tooth discoloration in young animals as is affects the tooth enamel
and calcium deposition all over the body. Never give doxy to a pregnant dog
or a puppy that doesn't have all adult teeth present (about 6 months of
age).
Baytril causes severe cartilage defects and joint deformaties in young and
growing pups and should only be used as a last resort (death vs. giving
Baytril). It should not be used on pups less than 1 year and not on any
pregnant bitches.
Chloramphenicol causes aplastic anemia in some people and after widespread
use in Vietnam is no longer used in human medicine. It causes birth
defects and also can affect the hormones of breeding bitches. Bottom line is
never handle without gloves and don't give to dogs that are intact.
Gentamycin/Neomycin/Amikacin can all affect the nerves of the ear and
cause deafness and are also toxic to the kidneys especially in young animals.
These antibiotics should never be given to pregnant animals or to young
pups.
Use extreme caution with antibiotics they are not generally safe nor have
they been tested on pregnant animals. The side effects are often life
threatening or extreme and life long.
As a side note, I just want to say that if you think a birth defect is
caused by these antibiotics which are considered an "environmental influence"
and not a genetic defect-then the ENTIRE litter will be affected because
all the puppies are exposed to the same environment-blood supply, nutrition,
etc. as the rest of the pups. If you have a GENETIC defect you will see
some normal puppies and some affected puppies-that is the way genetics works
especially with recesssive genes. The only confusion occurs if there is a
DOMINANT inherited gene that all pups would inherit and therefore all be
affected, luckily there is almost no dominant genes that cause birth defects
because these are easy to eliminate from the gene pool-you will always see
an affected individual. The recessive genes are the ones in hiding that
sneak up on us occassionally in a litter.
Cryptorchisim:
Is believed to be some mode of recessive inheritance (big surprise) and is
considered genetic. There have been several studies that have shown
cryptorchid males are more likely to produce cryptorchid offspring, but can
produce normal offspring as well (A CARRIER). The main problem with
cryptorchid males isn't there ability to breed, but the problems that are
caused by
they undescended testicle. The undescended testicle is the real problem and
often becomes a sertoli cell tumor (10 times more likely than a normal
testicle). This is a type of cancer and if internal can metastasis or cause
sex-hormone secretions disrupting the normal hormones of the body.
Sorry for the length,
