Hi
Knotting a dogs penis is not taken literally it is not tying a penis in a knot it is when the dogs penis gets stuck in the dogs vagina and he begins ejaculating
usually in reference to dog mating where the male dog penis develops a large "knot" at the end during mating.
In short, yes. The full biological/zoological answer, however, is much more complicated. The knot one would normally find in a dog penis, known scientifically as the Shrodenburger Knot, is based on the type of knot one would normally use to tie ones shoes. The knot found in a skunk penis is of a different sort, and is commonly compared to the type of knot one might use whilst sailing, or tying a noose.
It's probably not swollen, when a dog has a full erection his penis will be quite large, often larger than a human's penis. The big lumps at the base of his penis is probably the part called the knot.
If you pull back his skin yes
Maniac Magee actually untied the knot, but Alexander the great scliced open th Gordian knot
Mastiffs are known for their excessively large knots
The "Dog's Knot", or medically termed as the Bulbus Glandis is a tissue in the structure of canine animal's penis'. When the dog mates, this tissue swells in order to sort of "latch" on to the female dog to prevent his penis from slipping out of her. This knot will stay swollen inside of the female dog even until after the male has ejaculated. You should never try to force mating dogs to part due to this. It not only could severely injure the male dog, but it could also rip open the female dogs vagina doing serious and even sometimes fatal damage to her as well. Given time, they will part themselves naturally.
Alexander the great cut the gordian knot into two with his sword. the old legend stated that who ever untied the knot would rule over all of Asia.
Our English Mastiff's penis is just over 14 inches long with a knot that is right at 6 inches in girth.
There isn't a particular legacy is known for for he was truly great but on of his legacies was when he conquered half of the known world when he was in his thirties, also there was th gordian knot which was a large knot that was untiable but Alexander found a lupol (he slices it in two with his sword)
The Hanover Knot is tying from an inside out staring position and forms a relatively large tie knot. Step by step instructions are provided in the link below -
