Dogs usually start to give birth about 60 days after pregnancy. The best mating time is from the 9th day of estrus to 12 day, that is, 9th day and 12 day. The 25th day after mating is the best time to do B-ultrasound. At this time, we can not only diagnose whether the dog is pregnant, but also accurately see how many babies the dog is pregnant with. The first 30 days of a dog's pregnancy is the most unstable period of its fetal heart, during which it is easy to have threatened abortion, so it is necessary to avoid dogs getting sick or eating toxic and harmful substances by mistake, and to avoid strenuous exercise. When the dog is pregnant for more than 45 days, it can be confirmed by X-ray how many are pregnant and how big the individual is. After 45 days, it is the fastest time for the fetus to develop. At this time, it is necessary to increase the nutrition of the bitch and supplement calcium at the same time to prevent the bitch from lacking calcium. 55 days, you can take another X-ray and do a B-ultrasound examination to determine whether it is caesarean section or natural delivery.

Usually in the 58-63 days of pregnancy, the bitch will become extremely anxious, walking around the kennel or scratching the walls and floors, which is a sign of childbirth. Don't panic in the meantime, make good prenatal preparations and leave everything to the bitch.

Prepare some clean old sheets or whole baby pads, and remember to absorb water, because there will be a lot of amniotic fluid and blood during production. If it all flows to the bitch, it is inconvenient to take care of it, and it is easy to breed bacteria and form skin diseases. Put the prepared sheets in a relatively closed space, and the bitch will build her own nest. Will wrap the sheets in the shape of a bird's nest and then lie in the middle waiting for delivery.
