The best time for male dogs to match, usually at the age of 2. After the age of 2, you will enter the best time to match dogs. Male dogs that have never been mate usually have sexual deterioration at the age of 5 to 6, often have dead or inactive sperm, and often have empty or difficult labor after mating with female dogs. Male dogs can be mated throughout the year, and the utilization period can be up to 7 or 8 years old.
The penis is the mating organ of a male dog, about 8 cm to 10 cm long. It can be inserted into the vagina without having to get an erection during mating. When the penis is inserted into the vagina, the urethra cavernosum and the penis cavernosum are rapidly congested and expanded. After about 1 hour of ejaculation, the penis cavernosum shrinks and the penis can withdraw. The amount of ejaculation is about 10 ml per ejaculation.
Sperm includes sperm and semen: sperm is flagellar cells, with a length of about 60 microns, divided into three parts: head, neck and tail. The sperm survives for a long time, and generally can survive in a female dog for 90 hours.
