I'm a retired maternity nurse, so know more than most about human physiology. I went back to school, to certify as a surgical technologist, so I have seen hundreds of human bodies from the inside-out. I have assisted in ooodles of C-sections.
It is NOT advisable for women to have more than 3 C-sections, even with our improved methods and smaller/safer incision. . Those who do, make the choice on their own, and not on the Obstetrician's advice.
When the incision is perpendicular, as the old-style C/S, the second pregnancy was at much higher risk to mother than the risks with today's bikini-cut incision. With each following C/S, when sewing up, it becomes more difficult to find good, viable tissue to suture. You can tell immediately if it is the third C/S delivery, and precaution protocols are initiated.. Now, dogs don't have a neat little uterus as humans do.
They have two uterine horns with multiple little bodies in them. C-section delivery is much more invasive. There is no neat little incision to get the pups out, so there is more compromised tissue for the next pregnancy.
Uteruses do rupture. Also, there is a good chance that the pups will have to be handraised, at least for a while, as the incision is between the breasts. There is a wound right down the middle of the belly, and it can be very painful for the ***** to nurse the pups.
( that isn't the case with humans, although scheduled C-sections do often result in mom's milk not coming in, because the hormones produced in laboring provide the signal for the milk to flow.) Most breed parent clubs have a code of ethics, that say that the member won't breed the ***** more than 3 litters. You sign that when you join the breed parent club. That code has nothing to do with C-sections, but is referring to normal whelping.
It IS a MAJOR surgery, as the body cavity is opened. The incision is made, and instrument is inserted to hold the bladder out of the way, the uterus (with infant) is lifted out and set on top of the body, the incision is made into the uterus, and the baby is pulled out. The uterus is cleaned out, sown up and put back in..then several layers of tissue are sown, up, and then the skin is sown or stapled.
Yep, it is major surgery. ( in minor surgeries, the body cavities are not opened) Now, an above answer stated that 'birthing' was the wrong term..That isn't necessarily so, as whelping prefers to the natural delivery, and delivering via C-section is often called 'birthing'.. (My answer was probably more than you wanted to know..lol..and would have been even longer, if my arm didn't hurt so bad.).
First off. A C section is major surgery. Any surgery that is invasive is a major surgery.
Second a humans reproductive organs and a dogs are entirely different. Human medicine, far exceeds what is practiced on animals...typically. In regards to humans.
A C section is something done in a life or death situation. Now, I understand there is a new trend for woman to plan a C section for no medical reason. IMHO this is asinine.
This is a very controversial subject and I would not say for a moment that it is safe. (for mom or baby) There are many studies that prove that this is not the way to go if you have a choice in the matter. I could go on but I will stop there.
Every C section a woman has increase her risks of complications with the next pregnancy. Uterine rupture, placenta attaching too low and the list goes on. Babies born via C section have a much higher risk of contracting pneumonia amongst other things.
This is a risk a woman takes on her own accord to bring forth children into the world. Those woman who choose this route over going natural really really need help. But that is just me.
Now when it comes to dogs this is a bit of a different situation. We are talking several offspring VS one. The uterus itself it entirely different shaped etc. I do not have a breed that "requires" C sections in order to be born so I am not even going to discuss that aspect.
However, I have had girls that needed a C section. I opted to spay at the same time. The one girl was too narrow pelvised and her pups were large.
There is a good possibility she could have passed this onto her female pups. So why continue the bloodline? The other female I purchased as a mature dog who had one litter.
I was never told her first litter was born via C section. I found out later it was due to a pup coming transverse. Anyway, her labor stalled out on her and I had to rush her to the vet for a C section.
My vet told me she had had a C section before and due to the amount of scar tissue the higher pups where unable to descend. Yup, she was spayed. I don't see any reason to breed a girl that cannot have pups naturally and put her life in jeopardy along with a tough recovery period just to get a litter out of her.
Why is a C section a major surgery? First of all it is invasive. Second, due to the blood supply to the uterus you can have major blood lose.
Third every time a dog is put under anesthetic there is a risk to her and to the pups. A C section by no means guarantees live puppies.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
