Researchers Use Dogs' Noses to Sniff Out Ovarian Cancer Pt. 2


What makes dogs' noses so keen?

According to PBS Online,

canines' sense of smell is upย to 100,000 times more accurate than ours

. To equate that discrepancy to vision - what humans see at a third of a mile, a dog could spy from more than 3,000 miles away with similar clarity. Pooches possess up to 300 million olfactory receptors in their noses, compared to the paltry 6 million in humans. In addition, the part of their brain that analyzes smells is a whopping 40 times larger than ours.

explained that canines predominantly interpret the world around them by smell. That's why dogs who are blind or deaf can get along well enough if they've been trained properly to cope with their disability. Their wet noses also serve as an advantage because the mucus captures scent particles. They smell pheromones that can be found in urine, feces, skin and fur. When they sniff another dog or person, they can learn a lot about himย simply from his odor.The strength of their noses starts at birth, as puppies have heat sensors that help them find their mothers during the time when their eyes and ears are still closed. However, these sensors disappear once they reach adolescence.According to Dogster, no matter how much you scrub your skin in the shower, dogs can still smell your "scent." To canines,

every human has a unique odor that acts as a fingerprint

and is practically everything they need to tell one person from another. Our skin regularly produces oils and fluids from sweat and sebaceous glands that create a particular scent, leaving trails of smells everywhere we go.With the right regimen of supplements and special dog foods, pet parents can ensure that their pooches are in top shape, from tail tip to nose.
