What Does the Nose Know?

I've been always fascinated by the dogs' sense of smell and how much they can see with their noses. Unlike our eyes, their noses allow them see not only what's right in front of them but things passed

Time viewing is possible.

You just have to have the nose for it. In the Winter I get a little glimpse into what my dogs see. For the rest of the year I can only guess and imagine.

I really love how this video illustrates the workings of the dog's nose.

This is what we see
This is what our dogs see
Must be like watching a surveillance camera.

I so wish I could experience it at least once.
