The estrus period of a normally developing female dog lasts for 21 days. The best breeding days are from the 10th to the 13th day when the female dog is in estrus. The breeding female dog is most likely to become pregnant. Therefore, the first mating is generally performed on the 10th day of the female dog's estrus, and then once a day, and 4 consecutive matings. The last mating is on the 13th day of the female dog's estrus; or the first mating is on the 10th day of the female dog's estrus, and thereafter. Mate once every other day and twice on the best breeding day.

How to mate dogs:

1. Help the dogs to combine naturally. Once it is determined that the female dog is at the peak of ovulation, the dog owner should quickly grasp the " "Golden Week" - that is, within 5 days, the female dog must mate with her dog husband.

2. The dog owner assists in mating. The female dog can start to get along with the male dog on the first day of estrus, so that they can get to know and become familiar with each other, and wait until the 10th day for official breeding. , it is easier for them to like each other, so it is best to let them "like" each other.

3. Artificial insemination, in addition to natural mating, animal doctors can also help dogs with artificial insemination

Warm reminder before mating:

< p> Before breeding a female dog, it is best for the dog owner to take the dog to the animal hospital and ask the doctor to do a vaginal smear examination, which can detect the date of ovulation. This is a good estrus check, which will be more conducive to understanding the dog's birth cycle, thereby increasing the chance of pregnancy.
