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).
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]

Dog sperm collection. In order to collect semen from a male dog, an artificial vagina is prepared, [15] [16] which is a conical thin latex sleeve ending in a sterile collection tube. The inside of the latex sleeve is lightly lubricated. [17] The male is allowed to sniff a female in estrus. Experienced studs cooperate readily in the process.
