Bit ot so thought best on this board but something I’ve been pondering this afternoon, animal farts, specifically dogs ones that’s been troubling me.

I’ve never had a dog that makes a noise when they do it - do any dogs or are mine all a bit private?
Also, when mine does, it stinks, which led me to believe that dog ones are the worst.
But If they’re silent, they could be doing it all the time, chuckling away while we are none the wiser?
