Do dogs mate butt to butt?

Answer 1

No, but I have seen situations where the dog (male) finishes his business, and wants to leave, and gets turned around butt to butt. The reason he cannot leave is that the female's birth canal muscles clamp the dog's hoo-haw in, so he cannot withdraw. This is all a normal part of the canine mating progression. Except maybe the turned around backwards part. Owie.

PS, sorry to use offensive terms like birth canal, female's and hoo-haw, but when I used the correct anatomical terms, my answer was trapped for using the correct words as being offensive. Deep sigh.

UPDATE: Its not the females clamping on the males. Its the males "hoo-haw" swelling inside the female.

Answer 2

At the time of penetration, the canine penis is not erect, and only able to penetrate the female because it includes a narrow bone called the "baculum", a feature of most placental mammals. After the male achieves penetration, he will often hold the female tighter and thrust faster, and it is during this time that the male's penis expands. Unlike human sexual intercourse, where the male penis commonly becomes erect before entering the female, canine copulation involves the male first penetrating the female, after which swelling of the penis to erection occurs.

Male canines are the only animals that have a locking bulbus glandis or "bulb", a spherical area of erectile tissue at the base of the penis. During copulation, and only after the male's penis is fully inside the female's vagina, the bulbus glandis becomes engorged with blood. When the female's vagina subsequently contracts, the penis becomes locked inside the female. This is known as "tying" or "knotting". While characteristic of mating in most canids, the copulatory tie has been reported to be absent or very brief (less than one minute) in the African Wild Dog, possibly due to the abundance of large predators in its environment.

When the penis is locked into the vagina by the bulbus glandis (when the stud is "tied"), the male will usually lift a leg and swing it over the female's back while turning around. The two stand with their hind ends touching and the penis locked inside the vagina while ejaculation occurs, decreasing leakage of semen from the vagina. After some time, typically between 5 and 20 minutes (but sometimes longer), the bulbus glandis disengorges, allowing the mates to separate.

Why would you ask such a question? You can see it.
