The best time for golden retriever mating:

1. According to changes in the vulva: Golden retriever 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.

2. Inference based on the initial stage of estrus: Most female dogs can be commonly known as "seeing red" based on the first vaginal bleeding. The day is designated as the initial period of estrus. Primiparous dogs are usually bred 12 to 13 days after "red", while multiparous dogs are usually bred for the first time 9 to 11 days after "red". Some older multiparous female dogs can even become pregnant 6 to 7 days after the "red", while the breeding date of some young and middle-aged dogs can be delayed to 13 to 15 days after the "red". Usually, the 12th day of "redness" is used as the basic reference number. Every time the female dog's age increases by 2 years or the number of parities increases by 2 litters, the first mating time will be advanced by 1 day.

3. Based on the performance of the heat test: For female dogs whose initial stage of estrus is difficult to determine, the best date for breeding can be determined by the heat test method. If the female dog 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 female dog presses the buttocks of the female dog with her hands, the tail root is raised to one side, and the labia are everted and frequently open and close; or if the female dog is When the dog's vaginal secretions change from red to straw yellow, and the above three symptoms are seen, the best breeding date is 1 to 3 days.

4. According to the vaginal mucus examination: take a vaginal mucus smear and observe the number of keratinocytes under a microscope. When the keratinocytes reach more than 80%, it is the best date for breeding. Because this keratinocyte is less than 10% during the estrus period, it gradually increases after entering the estrus period. In addition, most scholars believe that after the first mating, female dogs can be mated again 1 to 2 days apart, using the same male dog or dual mating with another male dog once to increase the conception rate and litter rate.

Things to note when mating golden retrievers:

1: When mating is in a tethered state, do not forcefully separate them, otherwise the genitals will be injured.

2: After the golden retriever completes the mating behavior, the male and female golden retriever dogs loosen their sexual organs and lick their vaginas respectively. At this time, the golden retriever dog should be quiet and can be put back to rest. Do not pull or drive it away immediately.

3: After mating, the female golden retriever should be allowed to lie down or stand in a position with the front low and the back high. Do not let the golden retriever sit down to preventSemen leaks out. Don't let the female golden retriever urinate, because urine is not conducive to the survival of sperm.

4: After mating, male Golden Retriever dogs often have a sunken waist, commonly known as "losing the waist". They must not be allowed to exercise strenuously.

5: After mating, male golden retrievers should not be allowed to drink water immediately. They should rest and move for a while before drinking water.

6: Keep golden retriever breeding records. Fill in the breeding time, male and female Golden Retriever names, breeds, parity, estrus date, expected delivery date, etc. in detail to maintain the bloodline and prepare for later inspection. It can be seen that no matter whether it is a male dog or a female dog, after the mating work, the owners need to help them with post-mating care, especially hygiene and feeding, as well as vaginal care. good. In this way, the golden retriever can continue to do the breeding work in the future. Otherwise, the breeding work will not be done, and it will also greatly affect the health of the golden retriever male and female dogs.

In summary, in the breeding process of golden retrievers, these related things have a great impact on golden retrievers. If the owners do a good job, it will be of great help to the golden retriever's future health and secondary fertility; if they do not do a good job, not only will there be no benefit, but sometimes it will also affect the golden retriever. health and life safety.
