How do dogs “see” with their noses?
Did you know that dogs smell in stereo? The ability to smell separately - with each nostril - helps them determine from what direction smells come. This is just one of the many ways that dogs’ wonderfully developed noses make them so scent-savvy.

No, I did not know that. Thank you so much for sharing this, and even though I don't always comment or remember to plus one, thank you so much for sharing these daily doses of interesting science on so many topics Corina Marinescu.

ReplyDeleteDogs have split noses... and so do cats, and mice, and many mammals. I think most of them should smell stereo.
ReplyDeleteThey can smell food a mile off too. Especially grilled sausages and bacon
ReplyDeleteFrom what I hear, the sense of smell is the deepest, most powerful sense in the brain.
ReplyDeleteTheir sense of smell is unimaginably greater than our own. I recently heard someone say that if you sprayed perfume at one end of a football field, a dog could smell it at the other end. That seems a bit extreme, but perfume can be a strong smell, so maybe so.
ReplyDeleteOne thing I've noticed with our dog, is that no smell is a bad smell. Except if it is so overpowering that he can't smell anything else. He doesn't like strong smells like glue, paint thinner, etc.
There's at least some evidence that other animals can use other senses to form image fusion and situational awareness, the way we do with our eyes: bats and dolphins may be able to form three-dimensional mental models of the world through sound, for instance. Dogs doing it with smell seems pretty reasonable. Maybe sharks with taste, and platypuses with electric fields.
