Why can dogs see presences better than humans?

[xise]

My 2 cents would be that 2D life is not veiled to the degree 3D life is.

This could well true. It's one of those notions that seems to be possible.

2D minds are limited by virtue of being less evolved, so it makes sense that the barriers need not be as great due to their inherent limitations.

Kind of like how a 7 foot wood fence will keep any dog from passing, but to keep a person out you need more like 100 foot stone walls, and even then any given man with the right tools can do it.

Then again, who knows. Creation sure is veiled in mystery, isn't it
