There's no doubt dogs have amazing sniffers, here's a list of fun facts about your pup's nose.
1. Dog sniffers versus human
Scientists have gauged the sniffing abilities of dogs to range anywhere from 10,000 to 100,000 times greater than a human's. While humans have one olfactory receptor, dogs have about 50.
2. Short-snouted pups are less smell sensitive
Flat-faced and short-nosed dogs such as the pug, Pekinese, Chihuahua and boxer, have fewer scent-detecting receptor cells than dogs with longer snouts, such as a German Shepherd or bloodhound, which have 225 million and 300 million, respectively.
3. Scent is incredibly important to dogs
As much, if not more so, as sight and sound – and it tells them far more about their environment than we can ever begin to imagine. If we can incorporate this into some of our games and behaviour training, we can discover a whole new way to interact with our pups and support them emotionally using such natural remedies as aromatherapy.
4. Dogs use their sense of smell more than sight
Dogs use their nose to explore and gather information and the part of a dog's brain that is devoted to analysing smells is, proportionally speaking, 40 times greater than humans. They gather information about their surroundings and other dogs through smell. By greeting each other with a butt sniff they can tell the age, sex, reproductive status, and health of the other dog.
5. Dogs' noses are made different than humans'
When humans inhale, we use the same air passage to both breathe and smell. Dogs' noses include a fold of tissue that separates the two functions. Both human and dog noses contain bony turbinates, or plates, but inside a dog's nose is a microscopically small, spongy membrane containing the scent cells. Like an accordion, if you could unfold all the crevices, the total surface may be as large as 1500 square millimetres.
6. Some dogs’ ears work with their noses
Many dog breeds feature long, floppy ears to give them the unique talent of fanning aromas up into their nostrils, making their noses all the better to smell with.
7. Scent-Tracking Pups Are Persistent
Some dogs are enthusiastic about all of the many things they catch a whiff of, but scent-tracking dogs zone in to find the source of the scent they're focused on.
