First of all, Samoyed dogs will all go through the period of estrus. The period of ejaculation refers to the period when the female dog reaches estrus or ovulates for the first time at a certain age, which is about 6-9 months old. At this time, as long as you mate with a male dog, you can get pregnant normally. However, it is not recommended to breed the dog at this time, because although the Samoyed dog is sexually mature at this time, its physical development is not yet complete, and its physical condition cannot withstand the effects of pregnancy. pressure.
The earliest time a Samoyed dog can be mated and bred should be when it is in normal second heat, that is, when it is 14 or 15 months old. After the Samoyed dog grows up to adulthood, it will go into estrus regularly twice a year, mainly in spring and autumn, that is, around March-May and September-November.
The breeding time can be determined based on the performance of estrus: For Samoyed bitches whose initial stage of estrus is difficult to determine, the best date for breeding can be determined by the estrus test method. If the Samoyed bitch likes to be close to male dogs, urinates frequently when encountering male dogs, and is willing to accept the male dog lying on his back; or if the Samoyed bitch’s buttocks are pressed with hands, the tail root is raised to one side, and the labia are everted and open and close frequently. ; Or when the vaginal secretions of a Samoyed female dog change from red to straw yellow, after seeing the above three symptoms, 1 to 3 days is the best breeding date.
The breeding time can also be determined based on changes in the vulva: Samoyed female dogs have obvious changes in their vulva after they are in estrus. First, the transverse diameter of the labia gradually increases and becomes softer. However, before ovulation, the transverse diameter of the labia shrinks sharply, then increases and shrinks again. When the transverse diameter of the labia shrinks every second time, it is the time of ovulation. Within 48 hours after ovulation begins, 80% of eggs can be discharged. The discharged eggs can survive in the fallopian tube for 4 to 8 days and maintain fertilization ability for 4 to 5 days. Therefore, the best date for breeding is 2 to 4 days after every second reduction in labia transverse diameter.
