Methods to determine pregnancy in Golden Retrievers

1. Blood drop determination method:

During a female Golden Retriever’s estrus, the female dog’s vagina can secrete blood. Counting from the first drop of blood from the vagina of a female dog in estrus, it is generally more appropriate for a primiparous female Golden Retriever to be bred for the first time on the 11th to 13th day thereafter. It is more appropriate for multiparous female dogs to be bred for the first time on the 9th to 11th day afterward. For every 2 years of age or 4 litters of parity, the first breeding time will be advanced by 1 day. In short, the best breeding period for most female golden retrievers is 9 to 13 days after the vaginal bleeding of the female golden retriever. However, there are also a very small number of multiparous female golden retriever dogs that have been in estrus for 5 to 5 days after giving birth many times. The vagina will stop bleeding on the 6th day, and you can get pregnant on the 6th to 8th day.

2. Vulva determination method:

If the date of bleeding from the female golden retriever’s vagina is not found in time during the estrus period, the best method can be determined based on the color change of the female dog’s vaginal secretions and the degree of swelling of the vulva. Breeding period. The initial color of the vaginal secretions of female dogs is red. The best breeding period is 2 to 3 days after the color of the vaginal secretions changes from red to straw yellow. In addition, when a female Golden Retriever is in estrus, her vulva will be obviously swollen and congested. When the vulva edema is significantly reduced and begins to soften, it is more suitable for breeding. You can also use your hands to open the female dog's vagina and observe. When the vaginal mucosa changes from dark red or red to light red or pink, it is more suitable for breeding.
