The estrus period of female dogs can start as early as 6 months after birth, and it can start as late as 1 month She only came into heat when she was half a year old. The interval between repeated estrus is 6 months, a total of 2 times a year. When the female dog is in estrus, her tail will be swollen and she will bleed continuously for more than 10 days. Generally, the dog will be weaned on the 10th to 12th day after the bleeding. These days are called the weaning period. Except during estrus, female dogs will not be interested in male dogs.
