Editing Knot (section)

==Tie==
The tie is when the male dog’s [[knot]] enlarges and becomes temporarily stuck inside the vagina or anus of his partner. If the dog is not very large then it will be easier to tie anally, although very big dogs are capable of managing a vaginal tie with women who are rather small or have very tight vaginas.

The tie may last from a couple minutes to half an hour, more rarely to upwards of an hour (reportedly). If the dog is too small, the tie will not be sufficient to lock inside and he will be able to remove his penis easily.

In some cases a dog may pull hard against the knot, causing an early pullout. This can be painful for the person and could be uncomfortable for the dog as well. Knot pullouts from the anus have more potential to cause problems as the vagina is comparatively elastic and resilient.
