Dog Farts
Id long wondered why, as a human, Mrs Kite can produce loud, ripping botty burps, but dogs just produce a face melting stink with minimal noise. Then one day it came to me; buttocks! Dogs have no buttocks to be parted and slapped back together when the gas escapes, whereas humans do!

And they say I waste my time.

Now we just need to convince scientists to fit a dog with buttocks
to prove your theory.

If I had to turn my arse inside out to poo,
then I don't think my sphincter muscle would be capable of clapping for sound.

My guess
Human beings learnt to walk upright, which rotates our pelviss. The last bit of your bum tube must get bent upwards, like a saxaphone, thus creating 'pursed lips' leading to a vibrant, noisy expulsion of gasses.

Experiment: Try sitting like a dog sits and fart. You'll probably just silently shit yourself.

It’s been postulated that the fart noise in humans came about as a warning call, used if a member of an early humanoid tribe met a sudden danger.

It’s detailed in the paper; Anal Trumpet Alarm Calls in Pre-Vocal Hominidea. Brunet, Michel; Guy, Pilbeam, Taisso, et al, Nature (Nature Publishing Group) 418 (6894): 145–151.

My dog has loud farts.
And they smell of road kill.

My dog
(now ex dog sadly) used to sit and let out a very small 'pfrrrrrt' and then look accusingly at his own arse.

Then at me. I made sure he knew I had noticed.
