What amazing facts exist regarding dogs' sense of smell? Dogs are undoubtedly more sensitive to smell than humans are. Therefore, it should come as no surprise that humans rely on our four-legged friends to use their noses for critical, even life-saving tasks. Examples of these tasks include training dogs to serve as service dogs, which can warn their owners who are epileptic about impending seizures or diabetics about dangerously low blood sugar. These are some incredible details on a dog's ability to detect smells.
1 - Dogs Have Excellent Odour Sense
1 - Dogs Have Excellent Odour Sense
A canine's sense of smell is 10,000–100,000 times more sensitive than a human's, according to scientists. Due in part to their greater number of scent receptors than humans, dogs are far better at smelling than humans. Dogs have roughly 50 scent receptors for every human scent receptor.
2 - They're able to smell human feelings.
We all understand that dogs can detect a treat or your meal of chicken at a distance of over a mile, but studies indicate that a dog's sense of smell is capable of detecting far more than just food (or trash, wild creatures, or your son's filthy socks).
Because dogs can smell adrenaline, sometimes referred to as the "fight-or-flight" hormone, their noses may detect fear and even sadness. When it comes to "smelling your fear," a dog can detect certain bodily chemicals that are released into the skin's surface due to an elevated heart rate or blood flow.
Because they may be trained to "smell" anxiety attacks and other negative occurrences in humans, man's best friend is sometimes used as a service and emotional support animal. Because diseases, such as cancer, leave behind distinct odor signatures in a person's body and bodily fluids, such as perspiration, breath, or urine, dogs are also able to "smell" diseases.
3 - A dog's ability to smell can decline with age.
You might see a decline in your dog's senses as they age, including hearing and vision. It turns out that as people age, their sense of smell, called olfaction, also deteriorates. In one study, researchers discovered that dogs older than 14 years old had atrophy on the olfactory epithelium in their nasal cavities and that senile changes to the olfactory bulb of their brains resemble those that happen in humans.
4 - Your dog thinks it smells you and your friends.
There's no disguising your distinct aroma from a dog, despite the fact that most people try to mask their natural body odors with deodorant and perfume and frequently shower. Yes, this is also the reason why many dogs greet you (or, even more embarrassingly, other dogs or family) by putting their nose right in the groin area. This area is home to many apocrine sweat glands, which create pheromones that provide your dog with significant social cues. Read This: Scent training for dogs at home
5 - Dogs Have a Unique Organ for Smelling
Nearly on the roof of a mouth in dogs is a unique organ called the vomeronasal organ, sometimes referred to as "Jacobson's organ." It is in charge of spotting pheromones, which are chemical cues that animals use to interact with one another in their species. Pheromones are used by dogs during mating to express anxiety and distress, as well as to strengthen the link between a mother and her puppies.
6 - There's another good reason.
Dogs Smell Each Other When you take your dog for a walk and he stops to smell the rear or genitalia of another dog, it might be quite uncomfortable. However, your dog is doing this for a cause; therefore, it's totally fine with them. Because a dog's sense of smell can truly detect information that includes what the new canine buddy recently ate and getting an estimate of their age, when dogs sniff each other, they are learning critical things about their new acquaintance.

In relation to that, canines are actually interacting with other dogs when they "mark" locations throughout the neighborhood. Therefore, a dog's method of keeping up with the gossip in the neighborhood is really to sniff trees (and then swiftly leave their calling card).
7 - Dogs Have Individual Nostril Scents
Dogs are able to smell with each nostril independently, according to a phenomenon known as "sniffing lateralization." When a dog initially begins to sniff, their right nostril is usually used for it. When faced with odors that are comfortable or familiar, like food, they usually switch to their left nostril. They stick with their appropriate nostril for scents that are unpleasant, scary, or stimulating. This relates to the brain's processing pathways. While the left side of the brain regulates behavioral reactions to known stimuli, the right hemisphere analyzes new information.
8 - The breed of your dog affects how strong their nose is.
Dogs differ in their ability to smell, and it's not always related to the size of the breed, even though every dog possesses a million scent receptors buried in their noses. Dachshunds, for instance, have roughly 125 million olfactory receptors; bloodhounds, on the other hand, have approximately 300 million smell receptors, more than twice as many, which is why tracking purposes frequently use them. With over 225 million, breeds like German Shepherds are in the middle. In order to put those astounding numbers into perspective, consider that the human nose has just over five million scent receptors. Read This: Dog Breeds Who Have Incredible Sense Of Smell
