How many days can a dog be mating after menstruation

Mating is generally 3-4 days after the dog has stopped bleeding. It is not recommended to mate when bleeding; otherwise, it will be failed to pregnant.

Please note that if the dog is less than one year old because it has not matured, it will cause miscarriage after pregnancy.

Secondly, the dog needs to get familiar with the male dog for 2-3 days before mating, increasing the chance of successful mating.
