The Chinese pastoral dog will be in heat for the first time when it is 8-10 months old, but it is not mature at this time and is not suitable for mating, otherwise it will cause great damage to the dog. Generally speaking, Chinese pastoral dogs start to give birth at about 1 year old, and the best breeding time for dogs is the 9-13th day when the bitch begins to estrus and bleed, because the bitch is willing to mate at this time. To ensure the conception rate, re-mating can be done 48 hours after mating.

Look at the upper limit of the reproductive age of the Chinese garden dog. Generally speaking, the life expectancy of a dog is between 12 and 14 years old, and their optimal reproductive age is 4 to 6 years old, which is equivalent to the appearance of people in their 20s and 30s. When the dog is 8 to 10 years old, that is, the period when people enter old age from middle age, their fertility begins to weaken, but it will not be completely lost. Although there is no academic article on the upper limit of the reproductive age of dogs in the domestic academic circle, but analogous to humans (after all, they are all creatures), the dog must be the older the age, the worse the fertility, the female dog is not as good as the male dog, and may be in the step. In old age, fertility is basically lost. So the upper limit for female dogs is 8 years old, and male and female dogs are 10 years old.
