Conception to Birth
I have always wanted to know what goes on inside my girls when they are pregnant.
I would count down each day and wonder
What do they look like now?
What is going on inside there?
So I decided to search the Internet and I have found some amazing articles and pictures that I thought others might enjoy as well.
***All the following pictures of the puppies in the womb were taken from National Geographic's web page.***
Pregnant dogs carry a litter for roughly 63 days. Unlike human eggs, dog eggs aren't mature when they are released from the ovaries, so they're not ready for fertilization right away. That's why the male dog's sperm will attach to the uterine wall, and wait for several days until the egg matures for fertilization. Because of the time lapse, mothers can bear puppies with two different fathers.
We start counting day one, the day the male and female mate for the first time.
For the first few weeks, we don’t see much change and we spend a lot of time wondering...is she pregnant or isn't she?
But INSIDE her, this is what is happening
Week One
DEVELOPMENT OF THE PUPPIES:
Fertilization occurs and a two celled embryo begins its life.
WEEK TWO (Days 7-14)
DEVELOPMENT OF THE PUPPIES:
The cell will start being a 4 cell and will separate into 64 cells. At this time the Embryos enter the uterus.
WEEK THREE (Days 14-21)
DEVELOPMENT OF THE PUPPIES:
On about day 18-20 the embryo will implant in the uterus.
CHANGES TO THE MUM:
Possible morning sickness.

WEEK FOUR (Days 21-28)
This is when the vet can palpate (feel) and possibly detect pregnancy.
DEVELOPMENT OF THE PUPPIES:
Fetuses grow from approximately 5-10 mm to 14-16mm, faces take shape,eyes and spinal cords developed.
CHANGES TO THE MUM:
She may have a clear, odorless vaginal discharge,
and her teats may begin to develop.

WEEK FIVE (Days 28-35)
DEVELOPMENT OF THE PUPPIES:
At this time the fetuses begin to look like dogs and sex can be determined.
Their toes, whiskers, and claws are developing.
Eyes that were open now close (When eyes are developing in the uterus, the eyes are
developed in an open position and then they close and remain closed until about 10 days old or so)
CHANGES TO THE MUM:
Her weight will begin to increase and
Swelling in the belly will begin to be noticeable
WEEK SIX (Days 35-42)
DEVELOPMENT OF THE PUPPIES:
Puppies become coloured (development of skin pigment)
CHANGES TO THE MUM:

This 3-D picture shows an embryo at 60 days
At 60 days in the womb, three days before birth, the puppy has developed a full coat of hair, with nails and paw pads, and the body is covered with touch-sensitive nerve endings. It has also displayed its characteristic panting in the fetus, a behavior that helps the dog regulate its own body temperature in the absence of ample sweat glands.
At this point, the puppy has also developed its defining sense of smell and hearing.
