The birth process of dogs
Dogs are prolific animals, because of their different breeds, the number of offspring per birth is also different. The average number of small dogs per fetus is 1-4, with a maximum of 6. The number of medium and large dogs is generally 6-9, at least 1-2, mostly 12-13, and 25 have been recorded.
The delivery of dogs is to expel the fetus and its appendages with the help of the contraction of the uterus, abdominal wall and diaphragm. The contraction of the uterus is intermittent, so the contraction of the uterus is usually called "contraction". The contraction of the abdominal wall and diaphragm is called "responsibility". The responsibility shrinks at will, and it is accompanied by contraction.
The time of delivery varies according to the number of babies and the physical quality of bitches, usually 3-4 hours, sometimes up to 7-8 hours, the interval between the birth of each fetus is 10-30 minutes, the longest interval is 1-2 hours.
During childbirth, the bitch often takes a side-lying position and constantly looks back on her abdomen, when the uterine muscle contraction is strengthened, and the pain is accompanied by labor pain. The labor pains of dogs can be divided into three stages: preparatory labor pains, labor pains and postpartum labor pains. Preparatory labor pains are caused by the opening of the uterus, which is characterized by weak and long intervals. Labor pains are labor pains caused by the fetus passing through the birth canal, which are characterized by intense pain and short intervals. Postpartum labor pain is the labor pains when the fetus is discharged from the fetal membrane after birth, which is characterized by weak and long gap time. When the duration of labor pains is shortened, the bitch breathes rapidly and gradually strengthens, and then lengthens her hind legs. At this time, you can see that there is a thin fluid flow out of the vulva, followed by the birth of the first fetus, while the fetus is still wrapped in the fetal membrane. the bitch will quickly tear the fetal membrane with her teeth, bite off the umbilical cord and lick the fetal mucus dry. If the first fetus can give birth smoothly, other fetuses generally will not have dystocia.
In the process of delivery, sometimes the fetal placenta produced in front has not been discharged, the fetus behind has been delivered, and some even have to discharge the placenta after all the fetuses have been delivered. If the placenta is not discharged immediately and the umbilical cord is still in the birth canal, the bitch may bite the umbilical cord and pull out the fetal membrane. Most bitches can eat the placenta.
If the bitch becomes quiet after giving birth to several fetuses, constantly licking the puppy's coat and no longer seeing the puppy after 2-3 hours, it indicates that the delivery is over, and a few give birth again after an interval of 48 hours, but most of the deliveries at this time are stillbirths.
Dogs in the first week after delivery, their vagina will also discharge brown-green lochia; 2 weeks after delivery, the uterus basically recovered. If you continue to discharge lochia, it is necessary to send it to the pet hospital for treatment in time.

Keep a dog and always have some clean water.
When keeping a dog, you should always put some clear water in a fixed position, so that it can drink at any time when it is thirsty, before and after exercise and before and after eating, so that it will not find another unclean water to drink. Especially in summer and autumn, when the weather is hot and dry, dogs especially need to drink clear water to supplement the evaporation of water inside. From the puppy period, if the puppy drinks enough water every day, it will develop normally and have a healthy stomach and intestines. Otherwise, frequent lack of water will easily lead to many problems, such as heatstroke in summer. Pour out the leftover water every day and change it to a fresh one.

Identification and management of hateful doe
Every year during the birth and lactation period of female deer, due to the lack of management skills in some deer farms, the phenomenon of hateful female deer harming newborn deer and feeding managers occurs from time to time. Some newborn deer are killed alive, and some breeders or technicians are scratched. According to the investigation, a sika deer hated female deer killed five newborn deer in the first few days of her birth, and scratched two young and able-bodied managers. The harm of hateful female deer has led to a significant increase in the mortality of young deer, which should be paid full attention to. 1 recognition
