When animals mate, specifically canines--I'm actually not sure about felines--the penis enlarges during climax and remains enlarged to the point where he is literally stuck inside the female for as long as it the mating process goes on.

This happens to ensure insemination, and the male can ejaculate several times before he is shrinks down small enough to unmount. This is used as a kink of sorts in hybrid / abo fanfictions.

Just before a dog cums the centre of it's penile shaft expands out. So the cum doesn't leak out.
Women into bestiality take great pride in being able to take the knot.

Being fully penetrated by a canine penis, including the bulbous 'knot' near the base, causing the two creatures to be locked together until the male is able to withdraw.
Max's Rottweiler had knotted the bitch, so they waited a few minutes to separate the two.

This is speaking of canid animals (members of the dog family; Canidae). A knot is basically a swelling of the Bulbus Glandis, a part of a canine's penis. The erectile tissue swells up during the climax of sexual intercourse and locks when it penetrates the female allowing it to inseminate into the female canine (probably because these canid animals miss when they hump the female so the semen will miss, I think).
Dirty Friend: "Lol. Look at that dog's knot. Now it's stuck with the female"
Other Friend: "You're disgusting. You're probably thinking about bestiality you furry freak."
