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 its 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:
1 | 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. | |
2 | Fido’s olfactory cortex – part of the brain – is 40 times larger a human’s. | |
3 | About 35% of a dog’s brain deals with odours – while only 5% of a human brain is devoted to smell. | |
4 | Dogs can use each nostril separately. | |
5 | Dogs inhale through their nostrils but exhale through the slits on the side of their noses. | |
6 | While humans can scent up to 10,000 different smells, dogs can sense 100,000 different odours. | |
7 | Which makes a dog’s nose about 100,000 to a 1000,000 times more sensitive than ours. |
No wonder our dogs want to spend so much time sniffing! And 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!
