When it comes to personal space, humans have clear boundaries. We shake hands, nod, or wave — we don’t sniff each other. Dogs, however, operate by different rules. Their version of “hello” often involves a nose in your crotch, and while it may leave you red-faced, to them, it’s simply polite behavior.
Dogs are incredible companions — loyal, loving, endlessly curious — but their quirks remind us they live in a world ruled by scent, not sight. That wet nose isn’t just cute; it’s a biological supercomputer gathering data we can barely imagine.
