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]

The most common form of sterilization in dogs and cats is surgical, spaying in females and castration in males. Non-surgical fertility control can either result in sterilization or temporary contraception and could offer a cheaper way to keep wild dog and cat populations under control. As of 2019, only contraceptives are commercially available.

The most common reasons for a dog to get a vaginectomy include cancer and chronic infection of the vagina. Tumors on the vagina and vulva of the dog accounts for 2.5%-3% of cancers affecting dogs and vaginectomies are one of the treatments to remove and cure the dog. [31]
HSG is considered a diagnostic procedure.It is used in the workup of infertile females to assess the patency of fallopian tubes, assess the competency of the cervix or congenital abnormality of the uterus in multiple miscarriages, assess the patency of fallopian tubes after surgery or tubal ligation, or before reversal of tubal ligation.
