Why do only canines have knots during mating?

Introduction: The Curious Case of Canine Knots

Canine mating is a unique and fascinating aspect of animal reproduction that has puzzled scientists and dog owners alike. One of the most striking features of canine mating is the presence of a knot that forms between the male and female during copulation. This knot, which can last for several minutes, is not seen in any other species, including humans. So why do only canines have knots during mating?

Understanding the Anatomy of Canine Mating

To understand the answer to this question, we must first understand the basic anatomy of canine reproduction. Dogs, like all mammals, have a reproductive system consisting of the male and female genitalia. During mating, the male’s penis becomes engorged with blood and expands, allowing it to enter the female’s vagina. The penis is composed of three parts: the root, the shaft, and the glans. Near the base of the penis, there is a structure called the bulbus glandis, which swells during mating and helps to form the knot.
