For domestic dogs the tie may last up to half an hour or more, though usually less. [7] When male canines are sexually excited, the bulbus glandis may swell up inside the penile sheath, even if the dog has been neutered. [8] The bulbus glandis also occurs in the penises of some pinnipeds, including South American fur seals. [9]
A dog's glans consists of two sections: Behind the lower, long part (pars longa glandis) lies the "knot" (Bulbus glandis) [1] which expands only after penetrating the vagina and causes the male dog to remain inside the bitch ("Tie") for some time after ejaculation (typically between 15 and 30 min).
The human–canine bond is rooted in the domestication of the dog, which began occurring through their long-term association with hunter-gatherers more than 30,000–40,000 years ago. The earliest known relationship between dogs and humans is attested by the 1914 discovery of the Bonn–Oberkassel dog , who was buried alongside two humans in ...

In dogs, the male has a knot in his penis that gets engorged with blood and ties the female, locking them together during copulation, until the act is complete. Male dogs have evolved this mechanism during mating in order to prevent other males from penetration whilst they are and the use of the tie enables them to be more likely to inseminate ...

The desire for sensual pleasure is usually the main motivation for humans, and sometimes the wish to have a baby or more children. [2] [3] The biological function of vaginal intercourse is human reproduction. During coitus without a condom, sperm enter the vagina, first with the pre-ejaculate and then a larger amount through male ejaculation. [4]
