To determine the exact date of the beginning of pregnancy to the first day of mating in most cases is problematic. That is why it is advisable to conduct special tests to determine at what point there was a release of an egg from the ovary into the fallopian tube.
This is due to the fact that a few days (up to 5) survive in the womb of the female sperm. They have a long way of development – from egg to formed fruit.
To dogs pregnancy was easy and not complicated by some unpleasant moments, it is important to know how the fetus develops week by week. That is why a pregnancy calendar for dogs is becoming a great tool for beginners dog breeders.
The first week (0-7 days)
In this phase, mating, fertilization, pregnancy begins. It is necessary to consider the following points: Do not always ovulate after the first mating. That is why you need to prepare for the test mating, which is carried out 48 hours after the first.

It is important to keep an eye on the dog’s health, provide her with good care and high-quality balanced feeding.
The second week (7-14 days)
The embryos are developing rapidly: down into the uterus and embryonic membranes are covered. The cells within the embryo begin to divide. Penetrating into the uterus, the embryos are introduced into its casing and fixed fibers. Formed the placenta ( “Children’s Place”), participated in this process shell and endometrium. Embryos size – about 0.5 mm.
The third week (14-21 days)
Embryos whose size has at least 1 centimeter, actively moving to the uterus and are distributed evenly in it. From the mother’s body through the placenta, they get the nutrients without which normal life is impossible. It begins the next stage of fetal development – formed organs of future puppies, central nervous system, brain, spine, front and rear paws.
It is necessary to exclude the impact of adverse external factors on the expectant mother, as they can also affect the offspring. Vaccinations and other interventions in the female body is not carried out during this period.
18-19 day fruit size has already reached 2 millimeters. Embryos are taking shape of the body inherent in mammals.

Fifth week (28-35 days)
In this phase there is an increase amount of amniotic fluid, which hinders probing of fruit in the dog stomach. Puppies are not so highly susceptible to developmental abnormalities. They are formed by claws, whiskers and genitals. At 30-32 day embryos size – up to 2 centimeters to 33-34 -. 2.7 cm in body weight was 20 weight% newborn puppies.
33 day delayed or completely closes the sky. If it does not, the puppy is born with a pathology incompatible with life – cleft palate.
Female putting on weight, it is caused by the presence of amniotic fluid and the rapid development of the fruit. The dog must receive proper food, feeding a fractional, small portions. In no case can not give the animal medicines and chemicals, as they will inevitably harm the offspring.
During this period, it is advisable to carry out ultrasound to determine how to develop the future of the offspring, if he has any abnormalities. Ultrasound allows you to set the number of puppies.
