How long can the big white bear see his belly after mating?

Personal experience! 3-7 days after matching, the bottom breast is slightly swollen (may be pregnant) for about 30 days. After the game, the bitch peach contract (may be pregnant) for 30 days. You can make a B-ultrasound diagnosis and search for the popular science video of Dog Uterine Diary! Can give you a clear and scientific explanation of this problem.

1 day, if the dog is deliberately bred, it is best to breed after 48 hours to increase the chance of pregnancy. If the pregnancy is successful, the sperm will go upstream along the cervix.

The next day, sperm will look around for mature eggs to combine.

On the second to third day, sperm occasionally have eggs in the fallopian tube.

On the 3rd-4th day, the egg coming out of the ovary will be fertilized in the fallopian tube.

On the 4th to 6th day, the fertilized egg will reach the uterus downstream along the fallopian tube until there is enough space for the embryo to grow. During this period, the egg will grow into a blastocyst.

From day 12 to day 14, the blastocyst will be implanted into the uterine wall.

From day 12 to day 26, the blastocyst will grow into an embryo, and some important organs will gradually grow out in the next two weeks.

From day 15 to day 22, the nipple of bitch will become larger and pink, and the hair around the abdomen and nipple will begin to become thinner.

From the 2nd1day to the 28th day, the bitch will appear colder than usual due to hormonal changes, or tension and expansion of the uterus, or morning sickness of pregnant women. You may also refuse to eat and occasionally vomit. Can eat less and eat more to help the bitch's appetite. You can also ask a doctor to prescribe some drugs for relaxing the uterus for dogs.

From day 26 to day 30, the embryo will be walnut-shaped, and experienced breeders or veterinarians can reliably palpate it to diagnose whether the bitch is busy with pregnancy and how many puppies there are.

Start to increase the dog's food intake on the 29th day, but don't overdo it to avoid excessive weight gain. Now the fetus has fully grown into a puppy.

On the 35th day, the bitch's abdomen began to bulge.

It is easy to feel puppies on the 45th day, so it will be difficult to count the number of puppies.

Day 48-56

Bitches will spend more time tidying up, their stomachs will swell more, and they may become a little restless and start looking for a suitable place to give birth.

On the 50 th day, the bitch may lose her appetite because her stomach is full of puppies, so it is best to give the dog less food and eat more. At this time, it is easy to feel the activities/movements of the bitch's abdomen.

From the 50th day to the 63rd day, the nipples and pudenda can be washed with warm water, and the hair around the abdomen and nipples can be shaved off, so that the puppies can easily suck breast milk after birth.

From day 59 to day 63, the nipple may shed some emulsion.

On the 60th day, the bitch's temperature can be measured in the morning and evening.

On the 62nd day, 24 hours before delivery, the temperature of the bitch will drop from 10 1(38.5) to 98(36), and some clear secretions will flow out in the shade.

The expected delivery date of the bitch on the 63rd day is only an average, and the delivery period may occur from the 59th day to the 65th day. Puppies born before the 58th day will be more difficult to survive.
