For domestic dogs the tie may last up to half an hour or more, though usually less. When male canines are excited, the bulbus glandis may swell up inside the penile sheath, even if the dog has been neutered.
The male dog then proceeds to position his prepuce behind the proximity of the female’s vulva. The female elevates her hind quarter and lowers her front quarter. The copulation begins when the glans has entered the vulva. The male will then thrust. In some cases, the female will experience discomfort if she is too young or has some reproductive issues.
Dog knot – The bulbus glandis, also known as knot, or dog knot, is an erectile tissue located at the top of the penis of dogs. During copulation, this tissue swells and locks up inside the female’s vagina. When the knot is swollen inside the vagina, this tightens it up to complete the lockup.
This prevents the penis from withdrawing until the dog has ejaculated inside. The circular muscles also contract, stimulating the ejection of semen.
When a female is in heat and has found the perfect partner, she will become calm and allow the male to mount her. At this stage, the penis is semi-erect or not erect at all. The process of mounting is described as the act of the male dog grabbing the female from her ribs.
