When is the best time for dogs to mate:

When a female dog is in estrus, the suitable breeding period is 2-4 days. Owners can calculate based on the time when the female dog's estrus begins. If the female dog's vagina is severely swollen, flushed or blood is found, it is the initial stage of estrus. Primiparous dogs usually mate on the 11th to 13th day, and multiparous dogs on the 9th. -The first mating time is 11 days. The first mating time for older dogs can be moved forward; usually the mating time is moved forward one day for every 2 years of age or 24 litters. Some high-yielding female dogs will go into estrus after giving birth several times. There will be no vaginal bleeding in 5 days, and mating will be successful on the 6th or 7th day.

The mating time of young and middle-aged dogs can be delayed by 1-4 days. If you do not find the initial stage of estrus with vaginal bleeding, you can calculate the best date for breeding based on the female dog's expression and changes in vaginal secretions. For example, female dogs are willing to be close to male dogs and urinate frequently when encountering male dogs. Let the male dog crawl, press the female dog's buttocks with your hands, lift the tail root to one side, and the vagina is everted and often opens and closes, which is the best breeding time; 2-3 days after the vaginal discharge changes from red to straw yellow Day is also the best time for mating. For female dogs that have no vaginal bleeding or excessive bleeding during the entire estrus period, male dogs can be tried. The best time is 1-3 days after mating.
