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 canine penis contains a baculum and a structure called the bulbus glandis that expands during copulation, forming a copulatory tie that lasts for up to an hour. [28] Young canids are born blind, with their eyes opening a few weeks after birth. [29]
In male dogs the glans penis is smooth and consists of two parts called the bulbus glandis and pars longa glandis. [56] The glans of a fossa's penis extends about halfway down the shaft and is spiny except at the tip. In comparison, the glans of felids is short and spiny, while that of viverrids is smooth and long. [57]
Bulbourethral glands are located posterior and lateral to the membranous portion of the urethra at the base of the penis, between the two layers of the fascia of the urogenital diaphragm, in the deep perineal pouch.
Fertilization typically occurs two to five days after ovulation. After ejaculation, the dogs are coitally tied for around 5–30 minutes because of the male's bulbus glandis swelling and the female's constrictor vestibuli contracting; the male will continue ejaculating until they untie naturally due to muscle relaxation.
