I'm not sure, thinking about it, that it would work with humans, as our colon is sort of upright, well, the ascending and descending parts are, as is the rectum.

Dogs' colons are presumably sort of horizontal, as are their bodies, so could easily be lined up with a directional compass point.

For humans to benefit, we'd have to poo lying down, or on all fours.
Pooing lying down we did as babies, and may well do again in our dotage, but pooing on all fours might necessitate developing some good propulsion techniques, and a change of toilet design.

This is interesting.

I'm trying to recall when and where I last saw our cats poo, and I'm afraid I can't be sure other than whenever I've seen them it's been on Marge's vegetable patch.

Now I've heard this, I'll keep an eye out. I know which way our garden is oriented, and I'll report back on each observed incident.

That made me laugh. Cats have no shame.

no, they don't give a chit do they

That made me laugh. Cats have no shame.

They have no idea of garden boundaries either! However, they do have a good sense of direction – they frequently do their business in the same place in my garden and they don't even live here!

That's just common sense.
