If you read this blog regularly, you’ve probably picked up that I love dogs. So of course I was excited years ago when  TED-Ed published a lesson about how dogs “see” with their noses. And I enjoyed it again this week after my youngest daughter asked me why our dog does so much sniffing.

How Do Dogs “See” With Their Noses? provides a great explanation of how dogs noses work. The most interesting part of the video is the explanation of how dogs’ senses of smell allow them to identify friends, foes, and potential threats. The video is embedded below. You can find the full lesson here.
