7 things to know about your dog’s nose
Dogs put their noses to work every second of the day but this can be troubling to humans – particularly when dogs sniff places and things we consider taboo, like private parts – canine or human! Dogs also like to sniff pee and poop … and all sorts of other stinky stuff. But it’s more than that. Your dog needs to scent and sniff to live a happy life. Sniffing for dogs is like talking for humans. They’re born to do it. To understand why, here are a few things you may not know about your dog’s nose:
- Your dog has a second nose. Its called a vomeronasal organ or Jacobson’s organ. A patch of sensory cells within the main nasal chamber that detect moisture-borne odour particles.
- Fido’s olfactory cortex (part of the brain) is 40 times larger a human’s.
- About 35% of a dog’s brain deals with odours, while only 5% of a human brain is devoted to smell.
- Dogs can use each nostril separately.
- Dogs inhale through their nostrils but exhale through the slits on the side of their noses.
- While humans can scent up to 10,000 different smells, dogs can sense 100,000 different odours.
- Which makes a dog’s nose about 100,000 to a 1,000,000 times more sensitive than ours.
No wonder our dogs want to spend so much time sniffing! Whilst some of those sniffs might make us squirm a little, perhaps we let dogs be dogs … forgive them for not adhering to human standards of propriety and instead marvel at the wonder of what that canine nose knows!
