Dog Birth
As the puppies start to pass through the birth canal, there is an even greater
effort of expulsion, which is probably due to a reflex occasioned by pressure
on the upper part of the vulva. This is true labor and is a useful fact to know
in helping a bitch to whelp. If you want to make her strain, insert a clean-gloved
finger in the vulva and pull upward and backward. She wig nearly always strain
and assist you. The average whelping time for dogs is five hours. Small dogs,
such as Cocker Spaniels, usually finish whelping in three hours, but large
dogs, such as Great Danes and St. Bernard’s, often take seven or eight hours. Twelve
hours is the limit of normal time for a large dog, although bitches have been
known to take thirty-six hours with no particularly abnormal aspects to the
whelping.
The contractions of the uterus push the young dog out through the vagina.
The puppy appears in one of several ways. It may still be in the amniotic sac.
If so, the sac must be broken or the newborn will suffocate. If the mother does
not do this, you should do it for her. The puppy may still be in its sac, but
the sac may have ruptured. Or the young may be born with the sac remaining
inside the mother. In this case, the umbilical cord is still connecting it to
the sac. The mother may chew this cord to break it, and the sac and placenta
will he discharged later. But you can wrap a cloth or tissue about the cord and
pull gently until the sac comes out with the placenta. If a placenta is not discharged,
it may or may not become a problem.
How do you know when the mother has delivered her last puppy? When is she
ready for ass examination and perhaps an injection? The birth process is a
natural one happening often in dogs all over the world. Most deliveries are
simple, normal events requiring only the mother’s help. But for the owner, the
experience of a first delivery is fraught with healthy concern that results in
more difficulty for him or her than for the dog. To relieve the anxiety, it is
wise to contact your veterinarian in advance of the accouchement, both to alert
bins or her and to ask advice. The veterinarians will tell you of any potential
problems of your breed and will decide, depending on the individual case, if
the female should be brought in after the whelping. If so, your vet may suggest
bringing the puppies in for an examination, too. The trip will be disturbing to
the new mother and is to be avoided in most cases, in our opinion.
The first puppy, frequently the most difficult to he birthed, may be the
largest in the litter. This may occur because the first pup develops at or
close to the bifurcation of the uterus, where there is a rich blood supply to
the developing fetus. A good many contractions may be necessary to force this
puppy's head or hips through the pelvic girdle. Sometimes the mother tires at
this point and this is a time when you may help her by donning a disposable
examination glove, lubricating your first and second fingers, inserting them in
the vagina and gently pulling that part you feel. She will then contract and
gradually you will be able to bring the head or the rear legs out of the canal.
Now, if the membranes have not ruptured with the head exposed, tear them and
dry the puppy's nose. Then wrap a dry dolls or tissue around the head and
continue gentle traction as the shoulders squeeze through the pelvic girdle the
puppy suddenly slides out with ease. If the delivery is breech, or hind legs
first, and the legs are out of the vaginal canal, the umbilical cord will be
under pressure, preventing the blood exchange circulation to and from the
mother. In this situation there is no time to rush to a veterinarian for help.
To save a breech puppy it is better to grasp the rear legs with a cloth or
tissue and exert enough traction to deliver it. Sometimes you must pull so hard
you may hesitate, but if you wait too long there is the danger of possible damage
or death to the puppy.
When a female is delivered of a puppy that appears dead or if you find one
during the whelping still in its sac, tear open the sac, dry the nose, and
holding the puppy in a towel in one hand, imitate the mother's licking motion
by rubbing it with the towel with your other hand. If there is still no motion
gently swing it through the air in an arc to force blood into the head, then
continue to stroke its sides firmly. Roll it over and stroke the other side.
Rub it roughly but not roughly enough to damage it, and don't give up easily.
If you lose a puppy or two, remember that for creatures of multiple births
it is natural for some to die. Some have birth defects and some are very tiny
by virtue of an inadequate blood supply to the uterus during development.
Studies of wild wolves in Michigan
find an average of only one pup from each litter grows to maturity and this is
adequate to perpetuate the species.
It would appear we may be overzealous in saving puppies that would die
without our help. Some of these dog must contribute defective genes to the gene
pool of all breeds. This may account for the seemingly fewer problems of mixed
breed dogs that as a group are not given the attention expended on our valuable
purebred dogs.
It also appears that a female may regulate the number of puppies she has,
provided, of course, she has been bred at the correct time. There is an
occasion some years ago to perform an exploratory operation on a champion
English Setter female to determine why she had not had a heat period in four
years. She had cysts on one ovary and all along one horn of her uterus. Half
her uterus was thick walled and diseased. The offending ovary and horn of the
uterus were removed. There had been an agreement between the breeder and a
prospective English purchaser that if she came in season and was bred they
would purchase her. She did indeed come in season two months after the surgery,
was bred, and shipped to England where she had twelve beautiful pups while in
quarantine. Twelve pups from half a uterus! Although we doubt she would have
beaten the world's record of twenty-three puppies with twenty-four pups if she
had had both horns of her uterus.
Birth defects are common problems. Don't be discouraged if you
encounter one from time to time. If you do find such a puppy, take it to your
veterinarian for euthanasia. He or she may send it to a pathology department
where records arc kept of these happenings. It seems to us there may be an
environmental basis for some defects and although we have urged different
groups to collect and classify birth defects, each declares there are no funds
available for it. It would seem that monitoring our dogs might disclose environmental
problems that can also affect mankind.
In our experience, delivering thousands of puppies an estimate about 20
percent arc born with a breech presentation. There is nothing abnormal about
it.
Normally a female will chew off the cord at varying distances from its
attachment, then eat the placenta and lick her young dry. This is unpleasant
for most people to accept, but it is part of a natural function and there is no
indication that interference is called for. However, it may be necessary to
crush the navel cord with blunt scissors two inches or so from the body if the
mother is unable to do it efficiently. There is good evidence that the
ingestion of the fluids, placenta, arid membranes by the mother in some way
helps the mother produce in her first milk immune bodies that increase the puppies'
resistance to disease. This milk is called the colostrums.
If you attend an dog giving birth you will find that your assistance and
affection are reassuring and that she will trust you with her young. If she has
a large litter, it is a good idea, when she is not looking, to hand the first
ones to a helper, who can put them in a warm, dry place to stay until the
mother is relaxed and ready to take care of them. In this way she can attend
each one as it is born, without injuring others from whom her attention has
been diverted.
Healthy newborn puppies are perfect examples of the inheritance of instincts
when, blind, deaf, and still wet, they seek out a nipple and attach themselves
to begin nursing - even while the mother is chewing their cords. It is a
remarkable sight to behold, no matter how many births one observes.
Why a hitch decides to eliminate a certain puppy from her brood is difficult
to ascertain. Perhaps a given pup has an odor she does not appreciate so she
pushes it out of the way with her nose. You find it and return it to her breast
and conic back later to find it once again excluded from the litter. A pup like
this should be removed to a container with a heating pad or heat light and
returned to the mother every two hours when it must be placed on a breast for
nursing. After a few days most bitches will then accept the previous reject.
Two post parturition infections in hitches are not common but do occur -
uterine infections arid infection of the breasts. Infection of the uterus is
unlikely if no placentas remain in the uterus. Normally a female discharges
from her uterus the lining to which the placentas were attached during
pregnancy and through which the young were nourished. This takes the form of a
dark red discharge and may last for ten or twelve days or even longer. Infected
breasts are extremely serious to both a mother and her young, and they require
immediate attention.
What Not to Do in Whelping. One often had been told about the most ludicrous
directions for helping bitches to whelp, especially those about the need to be
sterile. These warnings" disinfect the scissors and hands"; "tie
the cord with sterile silk" are overzealous applications of the human
birth precautions. With dogs you need pay no attention to such nonsense. Every
puppy is a bacterial flower garden almost as soon as it is born. It comes, bacteriological
speaking, into a filthy world. If its mother is left to herself, sire may allow
it to drop into a manure pile; and even if this happens it will be unaffected.
You can be as sterile as you wish and in spite of your efforts the puppy will
be an ideal breeding ground for bacteria. Its mother's breasts and legs, its
nest, hair, and intestines are teeming with them. Fortunately, most of these bacteria
will be benign, and nature has equipped the puppy to combat the others. The
most important precaution for you to observe is to avoid handling puppies after
you have been handling sick dog. You have far more to fear from viruses and coccidiosis
spread by flies than from contamination from well-washed hands or clean home
instruments.
The End of Whelping. One by one the puppies are pressed through the
birth canal until the last pup and the last placenta have been expelled. Then,
and not until then, will the bitch become relaxed and calm.
Using the method of palpation, it is possible to tell a great deal about
birth just as it is possible to diagnose pregnancy. One fact that can be
ascertained is when a cesarean operation is necessary. By reaching up from
underneath and placing the fingers on one side of the belly and the thumb on
the other, you can clearly feel a puppy entering the pelvic opening. If you
find that the puppy is in the birth position and the bitch is straining but
accomplishing nothing, check the situation again in a few hours. If the puppy
is in the same position, get the dam to your veterinarian. He or she may be
able to extract the puppy with special forceps or may have to perform a
cesarean section.
Palpation can also be useful in determining whether or riot the bitch has
finished whelping. If you have not had practice in this technique, hold one of
the newborn puppies in your fingers and then feel through the abdomen to see if
there is a similar object contained within it. Some persons prefer to feel with
both hands, keeping the fingertips of each opposite the other. This is
particularly helpful in the case of large itches.
Birth can take a few minutes for one or two puppies to perhaps twenty-four
hours for a large litter. If, after having a puppy, the mother relaxes and does
not appear to be having contractions, take her out of the nest for a walk. As
she pulls to return, release her and she will runback. This exercise will often
start strong contractions. Walking the female up and down a staircase a few
times has the same effect. If you choose to walk her outside at night take a
flashlight. Many bitches, appearing to urinate, are passing a puppy.
When you think the last puppy has been horn, wait a few hours before you let
the mother out. The great pressure on her bladder and other organs has relaxed
and she can and naturally does go a long while without elimination. If she
refuses to leave her pups twelve or sixteen hours after birth, take her for a
walk, unless she is in a pen where she can go out at will. If she is in a pen,
she will wait until it is dark and very quiet before going out.
Before the young are born, the mother should be prepared for suck-ling by
being carefully cleaned and having long hair cut away. It often prevents the
young from reaching the teats.
Breasts often cake because a mother produces more milk than her young need.
This is inevitable when her litter is small. Caked breasts are normal and the
symptoms usually disappear without medication. Sometimes a mother dies during
parturition or when her litter is very young. Although it is not easy to save
the orphans, you can probably raise them successfully if you understand their
needs. This means that you have to understand what their mother would supply if
she were living.
A wise dog owner will look carefully at the puppies' navels every day to see
that they are healing. The dried-up umbilical cord drops off sometime during
the second day, although occasionally puppies will have it much longer. After
this, healing should progress rapidly.

copper, iodine, zinc, cobalt, fluorine, boron.
