Breed sizes based on personal experience (I thought this would be help full with people wondering)

I can share from my personal experiences (at least the ones I can remember). I would also say this: there is quite a bit of individual variation, even within breeds. Breeds that have been more in-bred, historically, tend to have fairly similar-looking penises and fairly predictable size...there's always the occasional outlier though. Breeds with a great deal of genetic diversity (Alaskan Malamutes, Mastiffs, Retrievers, etc...basically breeds that have been around a long time and can be found in fairly sizable numbers) have the most variation in the appearance/size of their genitals. I know many of these are a small sample size in a fairly small region of the world, but I will share what I have seen anyway. I have measured many boys and I have enough experience from the ones I have measured to give a pretty accurate recollection of how big the others were that I've had the chance to interact with (at least within a half inch or so)

  • Akita (2): 6 3/4"-7 1/4" x 9"-10" knot girth x 5-5 1/4" shaft girth...one thing to be noted...the two I've seen...also other I've seen in videos...they have the most disproportionate shaft length to knot size ratio I have ever seen on a dog...pretty much all knot...lol!
  • Alaskan Malamute (7, 2 mixes): smallest 6 1/4" long x 7" knot girth x 4 1/2" shaft girth...largest, 2 that are exactly the same dimensions and not related: 8" long x 8 1/2" x 5 1/8"...the girthiest-shafted boy I have seen was 5 1/2".
  • American Bulldog: mix: 8 3/4" x 7 3/4" x 4 3/4".
    • (arcticwolf69): pure 71/2" x 7 1/2" x 4 3/4"
    • (anonymous) 7 1/2" x 7 x
    • (anonymous) 8 1/4" x 7 1/2 x
  • Bloodhound: (3, one mix): 8" long (shortest)-8 3/4" long (longest) x 8 1/2-9" knot girth x 5"-5 3/4" shaft girth
  • Boerboel: 7 1/2" long x 10 1/2" knot girth (girthiest I have seen in any breed) x 5 1/2" shaft girth .. measurement pics posted below
  • Boxer (Renee) 6.5" length from behind knot, 7.5" knot girth, 5"+ shaft girth.
  • Chesapeake Bay Retriever (1): 8 1/4" x 9" x 5 3/8".

  • Doberman Pincer (knotinterested)(Standard) Weight Unknown - Size 7" Girth 5" Knot Girth 7"
  • German Shepherd Dog (at least 8, few mixes): shortest was a fixed male who had the smallest cock I have ever seen fixed or not, on a dog that size...literally was a micropenis at about 3" in length.
    • intact GSDs, I've never seen one shorter than 6 1/2" nor one longer than 7 1/2". Least girthy knot about 7", girthiest around 8 1/2", least girthy shaft, a few were under 4 1/2" for sure. The girthiest shafted shep I've seen is barely over 5"...they tend to be longer, rather than girthy...the German lines are a little girthier.
    • (knotinterested) (German Bloodline) Male Dog Weight 125 pounds - Size 8" Girth 5" Knot Girth 8"

  • Staffordshire Terrier mixes (at least 10). Smallest one at about 5 1/4" in length. Longest at 7". Smallest knot at about 6", largest at about 8 5/8", least girthy shaft at about 4 1/4" and girthiest at 5 3/8".
  • Saint Bernard:8" long x 9" knot girth x 5 1/2" shaft girth.
    • (fanspaztic) 9" knot girth 10.5" measurement pics posted below
Hope this helps for anyone looking for a scientific answer <3 ...Btw, dogs with 10" cocks are unicorns. I'm sure they exist, but I've never seen one, and I've seen a LOT of dog cock...I can only think of maybe 2 I've ever seen in pictures or videos that probably are over that mark...anyone that tells you they have a dog with that long of a cock, or with a "softball-sized knot"...they're probably exaggerating...just like how guys love to overstate the size of their own penis by a half to one inch all the time (inferiority complex)


Please Post your actual measured sizes of dogs you have known to be added to the list
This is a question that gets asked a lot, lets have an actual compiled list of sizes

added 2 American bull dogs( anonymous) seen measurement pics, thanks a bunch buddie

I have known many many dogs of various breeds over the years but have never taken actual measurements of them except for my current american bulldog 90lbs of pure love
 
All measurements are my Best Guess - But I am pretty good at guessing the size of things.

German Shepherd Dog (German Bloodline) Male Dog Weight 125 pounds - Size 8" Girth 5" Knot Girth 8"
German Shepherd Dog (American Bloodline) Male Dog Weight 85 pounds - Size 7" Girth 5" Knot Girth 7"
Labrador Retriever (Chocolate) Weight Unknown - Size 6 1/2" Girth 5" Knot Girth 7"
Great Dane (Black and white) Weight Unknown - Size 9" Girth 6" Knot Girth 9"
Rottweiler (Standard) Weight Unknown - Size 8" Girth 5" Knot Girth 7"
Doberman Pincher (Standard) Weight Unknown - Size 7" Girth 5" Knot Girth 7"
Cocker Spaniel (Blonde) Weight Unknown - Size 5" Girth 4 1/2" Knot Girth 5 1/2"
 
This is a very nice thread, it includes information that I have been looking for
 
Boxer- 6.5" length from behind knot, 7.5" knot girth, 5"+ shaft girth.

He weighed 90 lbs and was tall, quite large framed for his breed.

-------------------------------------

Depth of thrusting

It should be kept in mind that since they are fitting their whole cock in, it will reach 1 to 2 inches deeper than a human penis of equivalent length, especially while thrusting.

Vaginal depth limits: if your vaginal max depth is 7", you can still probably knot a 7" long dog cock because after the knot swells inside, the opening of your hole is pulled back out of your pelvis just a little as it stays at least somewhat closed behind the knot. Be comfortable with deep pressure on your upper limit. I don't think deep thrusts from dogs are cervix beaters because after they swell quick and are reaching deep, the tip of the cock is in deep up in a vaginal fornix deeper than the cervix is. If the vagina and knot or a snug match, his tip will stay in deep and the thrusts will be like 2 inches of movement..... staying deep.

-------------------------------------

Frequency of not staying knotted in amateur vids

This is quite often the case in vids of male dogs penetrating someone vaginally. You can see in the measurements given so far, that frequently the knots are the 7" girth range. Especially on the med to large size breeds that are a little more common for people to have as pets. It's not hard for 7" girth to pull back out of a vagina. Vaginal openings vary in size or tightness a little too, of course.

More often though, it depends on if the dog pulls much, and which directions. If its a gentle steady tug upward, the knot is more likely to stay lodged inside. Also, some dogs pull more than others. There's ways to manage this somewhat. Having a person to help is one, but placing yourself near a piece of furniture or wall that reduces the chances of them turning-the-tie may be helpful.

This goes for receiving anal too. Those of us that can accomodate 10" girth may have a harder time tieing with a 7" girth knot. Think about position to help you. A smallish bathroom helped me experience a 15 minute tie.


-------------------------------------
I agree with the OP, that in years of seeing cocks (mostly online for me) maybe just a couple looked to be truly over 10" in length. One being a big Dane mounted on a standing pro actress.

The Akita seems like a really ultimate big thick knot with a shorter length. I've also seen a couple of dogs in amateur clips that look to be German Short Haired pointers that have a wide knot, and tie well, while not being a huge dog in body size.

Ok idk if this is an unpopular opinion, but my god did humans get the short end of the stick (no pun intended) when it comes to genitals, both male and female. Like shit we have such average reproductive organs

Actually, humans have some of the most gigantic reproductive organs in the animal kingdom when considered in comparison to body size. Yeah, great - a blue whale has a 10-12 foot long pecker. And he's also 80 feet long and weighs something like 70 tons. But in proportion to his body size, he's a comparative pin-dick - Any remotely typical human male puts him TOTALLY to shame in terms of penis size to body size ratio. And that holds true for *ALMOST* every animal that has a penis. We humans have freakishly huge cock size to body size ratios in comparison to the rest of the animal kingdom. (As a counterexample, look at gorillas... But bring your magnifying glass... Big, badass apes, sure, but if one of them can boast a whole two inches of cock, he's the gorilla version of Long Dong Silver.

Im talking about how interesting human genitals are. Male humans just have a muscle stick with no special traits, and female humans have a slit with no traits. It just feels like something cursed our species to not have interesting genitalia lol

No human male have a mushroom head that can be use as a plunger. Our penis is the same size from the base to the tip. A bitch will feel the fullness even without a knot. Human can last longer than a male k9. Most f/m video the sex is only about 3 minutes without knotting. My bitch knows I will take my time and she is in for 10-20 minutes of sex.

Human females have more than a slit. Depending the position the have a dog can enjoy her fat vulva without waiting for her heat.
He can fuck her missionary or old school doggy style. They take the knot like any k9.

I mean when you think about it, human genitals are designed for long sessions of in and out, in and out... for like 10,20, sometimes up to an hour or more of sex. can't imagine you could do that with one-n-done genitals with the bells and whistles most animals have that are designed for efficiency.
 
I have a mixed German shepherd dog with a Bernese dog and he has a huge cock from the antenna to the node 19cm thick 13cm node 7cm and 13cm in circumference. yes with a monster
Can... can we see.... plz....
