The Dog’s Nose Knows

This is part one of a series about our dog’s noses and their sense of scent.  Science is learning all the time,  all kinds of things about what “the dogs’ nose knows” !

Most of you are already aware that when it comes to sensitivity to scents or smells, dogs are paws-down winners over humans.  I’ve seen figures indicating that a dog’s sensitivity is from 10 to 100 to 1,000 to 1,000,000 times better than a human’s. I have found in my research that dogs can detect some, if not most, odors at concentrations of parts per trillion!

Dog noses are so amazing! The more we know, the more we want to know!  Canine “sniffing ability” is being studied more than ever before at universities all around the world.

Research indicates that dogs can smell fear, anxiety, even sadness. The flight-or-fight hormone, adrenaline, is undetectable by our human noses, but dogs can apparently smell it. In addition, fear or anxiety is often accompanied by increased heart rate and blood flow, which sends telltale body chemicals more quickly to the skin surface.

I will be posting some VERY interesting facts about dog’s noses and their sense of scent so stay tuned.

Watch how the dog’s nose knows as he sees his world around him through his sense of scent:
