Dogs experience the world primarily through smell, not sight.
- Humans: rely on vision
- Dogs: rely on scent
A dog’s nose is estimated to be 10,000–100,000 times more sensitive than a human’s. So when they meet someone, they don’t “look” first—they smell first.
Why That Specific Area?
The reason dogs often go for that particular spot is simple:
It’s one of the strongest scent zones on the human body.
That area contains:
