Teach you about the dog’s reproductive system? An introduction to the dog’s reproductive system! Nature is a magical existence. Nature has created many lives and taught them to use mating to reproduce the next generation. There is no other difference between dogs and humans. Same, then let’s understand the system needed for the reproduction of life!

Male dogs

1Testicles Teach you about the dog’s reproductive system? The dog's testicles are small, located in the scrotum, with one on each side and an oval shape. They are the organs that produce sperm and male hormones. During the reproductive period, the testicles are enlarged, elastic, and highly functional, capable of producing large amounts of sperm. During the anestrus stage, the testicles become smaller and harder, and lose the ability to reproduce. The role of male hormones is to promote the development and maturation of reproductive organs and maintain normal reproductive activities. Lack of male hormones will lead to underdevelopment of reproductive organs and loss of desire and ability for reproductive activities. 2. Insemination duct Teach you about the dog’s reproductive system? Including the epididymis, vas deferens and urogenital tract. The epididymis is the place where sperm is stored and allows the sperm to reach physiological maturity without omission, so that it has the ability to fertilize the egg. The vas deferens is the tube that carries sperm. The urogenital tract is the common passageway for urine discharge and ejaculation. 3Accessory sex glands refer to the prostate. Dogs do not have seminal vesicles and bulbourethral glands. The secretions of the prostate have the function of nourishing sperm and enhancing sperm motility. 4, Penis Teach you about the dog’s reproductive system? It is the copulatory organ. The structure of the dog's penis is quite special. First, there is a penis bone about 8 to 10 centimeters long; second, there are two well-developed sponge bodies at the root of the penis. During the mating process, the sponge bodies become congested and swollen, and become stuck in the penis. The female dog's pubic symphysis makes the penis unable to be pulled out and becomes embolic.

Female Dog 1, Ovary Teach you about the dog’s reproductive system? Located on the ventral side of the third or fourth lumbar vertebrae, it is oblong, slightly flat, and is the organ that produces eggs and estrogen. After a sexually mature female dog reaches estrus, a batch of eggs will mature and be discharged. If sperm is encountered, they can be fertilized and become pregnant. The role of estrogen is to promote the development of female reproductive organs and maintain reproductive functions. 2、Oviduct Teach you about the dog’s reproductive system? It is a tube that transports eggs and fertilization, and is about 5 to 8 centimeters long. After the egg is released from the ovary, it enters the fallopian tube, where it meets the sperm, completes the fertilization process, and is transported to the uterus for development. 3The uterusis the place where the fetus develops. The dog's uterus is a bicornuate uterus, with slender uterine horns, uniform inner diameter, and no curvature. The uterine horns on both sides are "V" shaped. The uterine body is short and small, only 1/4~1/6 of the uterine horn. The fetus develops in the uterine horn. Because the uterine horn is relatively developed, a litter can produce up to a dozen puppies.

4． VaginaTeach you about the dog’s reproductive system? It is the channel for mating organs and fetal birth. The dog's vagina is relatively long and has well-developed circular muscles. 5． Vulva Teach you about the dog’s reproductive system? The external reproductive organs, including the labia and clitoris. It often changes regularly during the estrus period, which is an important sign to identify whether it is in estrus or not.
