> All women can feel a knot thru their tummy with their hands, and a lot of women, especially petite ones (like me) can visually see their knot 
Nope. Not unless you own a great dane or something with a monster cock. Already can tell she's picked this up from hentai and online erotica fiction.
>A dog cums directly into a girls womb thanks to their pointed cock which creates a warm, full feeling inside girls which often contributes to the intense orgasms, while men's cock which is curved away from the cervix makes it impossible for a man to ejaculate in a girls womb directly.
First off, fuck you whoever wrote this for actually making me look up the average length of a dog penis.
Male penises are not curved away. Already bullshit.
> Dogs ejaculate far more volume than necessary to totally fill the womb and it often results in very visible belly swelling that stays there for hours or even days. the remaining cum often drips out the cervix and needs girls to wear maxi pads (I have been doing this even tho I'm not on my flow), and the rest is absorbed by the body
Dogs and humans have close to the same volume. 5-6mL. This "visible belly swelling" is yet another myth picked up by someone spending too much time in 'tismoland.(And I don't think the body absorbs semen)
> Dog knots directly stimulate the gspot which creates a state of high, consistent constant pleasure for a girl the heaven-like state is punctuated by often dozens of earth-shaking orgasms
This can't be debunked, because the g-spot can be stimulated through penetration. However, dogs are not the only ones with dicks capable of this. This is not a specific characteristic that separates beast and vanilla sex. Ergo, wrong again.
> Dog cum is very beneficial t-
No.
> Dogs have around 900% MORE sperm cells per drop of semen compared to the most fertile men which is an astounding feat considering the amount of ejaculate they make!
Dog sperm has no effect on humans. That out of the way, both dogs and male sperm functions the same biologically within it's own species/family. Their fertility is defined by diet, exercise, sunlight, habit, and genes. Purebreds have the lowest fertility rate of dogs, and they have other reproductive issues on standby often than not. That Rottweiler you pounded isn't getting you pregnant, and probably couldn't even pump a load of baby into his queen if he wanted to.
> Dogs ejaculate 8-16 BILLION sperm cells in a single orgasm. The most fertile men ejaculate 300 million
Again way off here. All males of all mammals ejaculate the same estimated amount of sperm to fertilize the womb, which is 500 million at best. This 16 billion bullshit is subjective to fetish.
> The average penis size for a large breed dog like a great dane, German Shepherd, husky, Labrador, etc. is 9 inches long and 6 inches of girth
See above image. There is no "six inches of girth".
> The average testicle size for a large breed dog is around the size of eggs, or around the size of both an average man's testicles combined into one.
I've raised well over six male dogs in my quarter-century lifetime, and I can confirm that they all have the testicle size of whatever is biologically matched in ratio to the rest of their body. Schnauzers and chihuahuas have tiny little sacs, while retrievers and bigger dogs have the drooping ones. There is no specific "average" size, nor does this play any part in reproduction in any form.
> A dogs makes enough sperm in 8 hours to impregnate every woman and girl on the planet twice
What am I doing with my life......
> If a dog were able to impregnate a woman it would take an astounding 24 seconds at least and 30 seconds at average to impregnate her.
