There are currently no effective oral abortion drugs for veterinary use on the market. If the dog is equipped with it during the estrus and does not want the dog to give birth, the most effective way is to undergo surgery to remove the uterus and ovaries to eliminate the possibility of estrus and pregnancy in the future. If you do not want to undergo surgery, you can go to the pet hospital for injecting hormone drugs in the early stage of mating to perform an abortion, but there are certain probability of abortion failure and have certain drug side effects on the female dog.

Dogs normally have estrus twice a year, and the first time they have estrus is about 7-8 months old. Those who are late may have to 1 year old. In the early stage of estrus, they will experience vaginal bleeding and bright red. You can get mated around the 10-12th day of the estrus. At this time, the probability of conception is higher. Under normal circumstances, after 18 days of mating, the gestational sac can be checked through B-ultrasound to determine whether you are pregnant. The pregnancy period of a dog is about 58 days to 64 days, and about 30 days of mating, it will be observed that the dog's abdominal circumference will increase. After more than 45 days, the breasts will develop and even milk will be produced.

If the dog is accidentally bred, it is recommended to undergo uterine ovarian removal surgery within 30 days of bridging, which will facilitate the female dog's post-operative recovery. The longer the pregnancy time, the greater the risk of surgery and the greater the amount of bleeding. If you don’t want the dog to give birth, it is recommended that the dog be sterilized at 7-8 months old. At this time, the dog’s postoperative recovery is better and the amount of bleeding is low. At the same time, more than 90% of breast diseases can be avoided. Unspained dogs are prone to gynecological diseases in the aging stage, such as uterine pus, uterine effusion, ovarian cysts, and breast tumors. The mortality rate is uterine pus and breast tumors.
