That's mean Beaker. LOL
Dog sex 101: Dogs have a long long uterus so they can line puppies up in a row. Male dogs cum a lot so the sperm can be pushed all the way up that long uterus. To keep his penis in her long enough for all that cumming to happen, they tie or lock together. The knot is an expandable bulb partway down the dog's shaft. The dog has a bone in his penis so he can insert it without a full erection. After he has it in, the bulb (and the rest of his penis) inflates and becomes larger than the females vulva. It stays that way until he is finished orgasming and she stays right where he wants her.

heaven and hell at the back of a dog dick,its the bulge in her hand

Berard, thats the best explanation of the subject that I have ever read.

hi all with the boin and knott growing will it hert you?
thanks bee

I am having a hard time getting the penis to come out of the sheath. Any suggestions will be of great help

It's possible, but the other end is more dangerous. Start slow and easy. Work up to taking the knot. I promise you that it's worth the time for both of you.
I spent 30 minutes tied with a St Bernard last night and there was nothing but pleasure for both of us. All it takes is practice.

First: It won't come out if his knot is swollen. You want him excited enough to hump and no more. If you jack him to completion, he will get lazy and expect you to do all the work.
Second: The shaft between the knot and the pubic bone gets longer but not much. Mostly his sheath slides down his dick by streching his belly skin and bunching up near his balls. This happens because when he humps, he rotates his hips until his dick is at a right angle to his body.
In proper dog sex the erection starts at the base of his dick. A little of his dick comes out of the sheath (showing pink). He mounts and uses that "pink" to feel for the hole. When he finds it, he humps his body and rolls his hips to push his dick into the hole. He spreads his back legs out and pulls with his front legs until his balls and pubic bone are against the hole.
In other words, you won't see his dick until he's done and pulls it out.

this is the knot,u wont feel it go in,but u will feel it swell inside u,becareful,hold his to front legs so he doesn't move and pull out,'IT HURTS'

ok know we know about the knott and what to do but how do i get him in the mood?

First: He has to be old/young enough, healthy, and all there.
Second: He has to know and trust you and his surroundings.
Third: Play with him. Tease him. Rub his dick and run away. When he gets excited, put your butt in front of him.
Fourth: When he mounts you, catch his dick with your hand. Aim him in but don't let go. Hold his knot until it goes back down.
After you get good at this and he has learned not to jump up or run off, you can do it without the hand and let him put it all in.

ty so mech i've been playing with him all this week i hsve got him in twice now but he dosen't wtay in for long. what do i do to keep him in?

I need the answers to a few questions. Does he have his nuts? What are your sizes? How old is he? Where are you putting him and how far in? After he comes loose, how big is his knot and for how long?

well yes he has his knuts.my size is 5 " 2' tall 130 lbs. he's a year and a 1/2.in me i'm not sure how far in he go's in. it about the size of a baseball.
