Normally, dogs go into estrus twice a year. The first time a puppy goes into estrus is about 7-8 months old. Late maturing may occur after 1 year old. In the early stage of estrus, there will be vaginal bleeding, bright red, and the 10th day of estrus. -In about 12 days, breeding can be carried out, and the probability of pregnancy is higher at this time. Under normal circumstances, 18 days after breeding, you can check the gestational sac through B-ultrasound to determine whether you are pregnant. The gestation period of a dog is about 58 days to 64 days. About 30 days after breeding, you will observe an increase in the dog’s abdominal circumference. , more than 45 days, the breasts will develop and even produce milk.
If the dog is accidentally bred, it is recommended to perform a uterine and ovary removal surgery within 30 days of breeding to facilitate the recovery of the bitch after surgery. The longer the pregnancy, the greater the risk of surgery and the amount of bleeding. It will also be bigger. If you don’t want your dog to have puppies, it is recommended that your dog be neutered when it is 7-8 months old. At this time, the dog’s postoperative recovery is better, the amount of bleeding is low, and more than 90% of breast diseases can be avoided. Unneutered dogs are prone to gynecological diseases in their old age, such as: pyometra, uterine effusion, ovarian cysts, and breast tumors. The fatal rates are higher for pyometra and breast tumors
