Most people who have a dog love their dog and think he or she is pretty awesome. But even if your dog is a snarling, yapping jerk that is mean and threatening to everyone (Yep, I’m looking at you, Scooby – dog across the street!), his nose is still pretty darned amazing. (and yes, we know you love him in spite of his jerk tendencies).

The video below, courtesy of the always awesome TED-Ed, takes a look at how your dog’s nose helps them to ‘see’ the world. You’ll better understand your dog’s olfactory prowess, and hopefully, let them sniff a little longer on their next walk!
