- Day 2 -3 - Fertilization occurs in the oviducts which lead
from the ovaries to the uterus.
- Day 4-6 - Fertilized eggs migrate down the oviducts and into
the uterine horns.
- The migration continue to enable even spacing of the embryos.

The fur on the dams belly and around the nipples may become
thinner.
Day 21-27 - Morning sickness might occur due to hormonal
changes or stretching and distension of the uterus. Dam may appear a bit apathetic.
She may be off her feed for a while and vomit from time to time.
Feeding the dam several meals spaced throughout the day might
help.
Your veterinarian may want to prescribe a drug to relax the
uterus.
Day 26 - 30 - An experienced person (a breeder or a veterinarian)
can tell by careful palpation whether the dam is pregnant.
It's now the best time to do this because the embryos are
walnut-sized now and easy to count.
Day 28 - Start to increase the dams food ration.
Don't overfeed, excessive weight gain should be avoided.
The foetuses are now and are fully developed miniature dogs.
Day 34 - The Dams abdomen starts to get larger.
Day 44 - It's very easy now to feel the puppies, counting
them might be a bit more difficult.
Dam begins to spend a lot more time in self-grooming.
Her breasts become even more swollen.

Day 47-55 - She may become a bit restlessness and begin to
search for a suitable place to have her puppies.
Day 50 - The dam might lose her appetite during this period.
Her abdomen can be crowded with puppies.
Day 50-64 - Dam has difficulty grooming herself.
It is better to feed several smaller meals spaced throughout
the day.
You can easily detect abdominal movement now.
Nipples and vulva should be gently cleaned with warm water,
you might want to trim the hairs surrounding the nipples, to allow easier
access for the puppies to suck.
Day 59-62 - Milky fluid may be expressed from the nipples.
Day 61 - You might want to start taking the dams rectal temperature
each morning and evening.
Day 63(?) - Twelve to 24 hours before she is due to deliver,
the dams rectal temperature may drop from 101 to 98 degrees.
Clear discharge from the vulva might occur.
Day 64 - Expected date of whelp. Of course this is just
an average. Whelping may take place from the 59th to the 65th day. Puppies
born before the 58th day will probably be too young to survive.
