The Dog Penis and its Reproduction

He Dog penis Is formed by the Baculum , Or bone of the penis. It is a bony formation that is found in the penis of many placental mammals like the gorilla or the chimpanzee but not in the human penis.

This bone is located above the urethra of the male, and intervenes in sexual reproduction maintaining the necessary erection during mating.

Baculum

The equivalent of baculum in females is known as the Baubellum or the clitoridis (Bone in the clitoris). He Baculum Intervenes in copulation and varies in size and shape depending on the species.

The bone in the penis favors attachment to the female for a considerable time, which ensures success in intercourse.

It is believed that the existence of Baculum Of the penis was already known by farmers and hunter-gatherers. It has also been argued that the biblical rib, in the history of Adam and Eve, is actually a mistranslation of the Hebrew biblical euphemism for Baculum , And that its removal in Genesis is a story created to explain the absence of the staff in the penis of humans, as well as the resultant perineal scar.

In the African American hoodoo (the popular magic of the American South), the Baculum Of the raccoon is used as an amulet of luck and to attract love.

The sexuality of dogs

Dogs reach sexual maturity and can reproduce during the first year of life. Although male puppies do not have the impulse to procreate, they usually engage in sexual games in the form of mounts, since the two months.

Small dogs tend to get into heat sooner than larger ones. In general, all males reach sexual maturity and are fit for reproduction during the first year of life.

Dog semen

In bitches, the estrous cycle is composed of four successive stages and has a single estrus (cycle) per cycle. The time between one estrus and another is approximately 7 months. Each estrus lasts on average 9 days, with spontaneous ovulation. Ovulation occurs within 3 days of initiating estrus.

Sexual Behavior

Male dogs are one of the few animals that have a blocking glandis. This is spherical and erectile tissue area, is located at the base of the penis. The bulb is swollen by blood supply during intercourse, but only after the male's penis is completely in the female's vagina. When the vagina contracts, the penis is blocked inside. In this instance it is said that the couple is tied / knotted or also attached.

At the moment of penetration, the canine penis is not erect, but achieves penetration thanks to the staff. When the male reaches penetration, he usually holds the female tightly and pushes hard.

It is during this time that the penis of the male expands and it is important that the penis is deep enough so that the female's vagina can contain and retain it (this situation is also called a copulatory block).

Canine copulation implies that the male first mounts the female and penetrates it, then the erection of the penis occurs. The male pushes against the female in rhythmic movements for 1 to 2 minutes.

The first ejaculation comes yellow, sterile because it contains no sperm. At this point the turning takes place (rotation of 180º): the male rotates and stays in the opposite position to the female.

Pregnant female

From the turning, with the penis still erect inside the vagina, the second ejaculation occurs, a white liquid loaded with fertilizing spermatozoa, which will leave the female pregnant.

Pregnancy is ensured because both remain in this position for 30 to 60 minutes. When the glans relax and shrink, then male and female separate. This dynamic is exclusive to dogs and wolves.
