In dogs, knotting is a form of copulation in which the male’s penis becomes locked into the female’s vagina (the equivalent of a human male’s orgasm). This usually happens when the male is about to ejaculate. If he does not withdraw after ejaculation, he can get stuck inside the female and be unable to pull out. This is referred to as being “tied” or “tied up”.

The act of knotting can be painful for both the male and female dog because their genitals swell to fit together tightly during this process.

In most cases, it’s best for your dog if you can separate them before they get too far along in the process. It’s also important that you realize that being tied up doesn’t necessarily mean that your dog will get pregnant if you don’t break them apart quickly enough.

If you know that your dog is going to be bred and you want it to happen naturally rather than by artificial insemination (AI), then you should let them mate without trying to stop them from mating more than once.
