why do dog get stuck after mating?
Have you ever seen a male dog get excited?
The males penis expands and creates a bubble on the end so that the female and male can stay together through the course of action. Sometimes it takes a while for the male to release.
Go get a book on Dog breeding.
It is also called the Dog Knot. The bulb of the knot is to the top of the shaft.
Never try to separate dogs if they are tired you can do serious harm to them
It's called a tie! They will release on their own, when they are ready to. Do NOT under any circumstances try to separate them, or you will seriously injure them both!
because the dogs penis expands right before hes ready to blow his load
