As we prepare to honor our four-legged friends on National Dog Day, let’s explore some fascinating anecdotes about them that you may not have known. Dogs never cease to astound us with their peculiarities and skills, from their extraordinary sense of smell to their unusual ways of communicating. So grab a snack and make yourself comfortable while we learn eight strange, little-known facts about the best friend of man.

Dogs Have an Incredible Sense of Smell

You’ve probably heard that dogs have a keen sense of smell, but did you know just how remarkable it truly is? To put it into perspective, a dog’s sense of smell is estimated to be tens of thousands of times more sensitive than that of humans. This extraordinary olfactory ability allows them to detect scents with incredible precision, making them invaluable assets in various fields, including search and rescue, detection of contraband, and even medical diagnostics.

They Can Detect Diseases

Beyond their role as loyal companions, dogs possess the remarkable ability to detect certain diseases in humans. Research has shown that dogs can sniff out subtle changes in odor associated with various medical conditions, including cancer, diabetes, and even malaria. In some cases, they can detect these diseases at an early stage, potentially saving lives through early intervention.

Dogs Have Unique Nose Prints

While humans are often identified by fingerprints, dogs have their own distinctive identifiers – nose prints! Just like human fingerprints, each dog’s nose has a unique pattern of ridges and creases. In fact, nose prints are being increasingly used for identification purposes in countries such as Canada and India, where they are considered legally admissible evidence in court.

They Communicate Through Tail Wagging

When it comes to communication, dogs have a diverse repertoire of behaviors, but one of the most universal signals is tail wagging. While it’s commonly associated with happiness, the truth is that a dog’s wag can convey a range of emotions, from excitement and joy to nervousness or even aggression. The speed, height, and direction of the wag can all provide valuable insights into a dog’s state of mind.

Dogs Dream Like Humans

Ever wondered what goes on in your dog’s mind while they’re snoozing? Just like humans, dogs experience REM (rapid eye movement) sleep, which is often associated with dreaming. Observations of sleeping dogs have revealed twitching paws, wagging tails, and even muffled barks – all indications that they’re immersed in their own dream world. So, the next time you see your pup dozing off, they might just be chasing squirrels in their dreams!

They Have a Third Eyelid

While humans have just two eyelids, dogs have a third eyelid called the “haw” or nictitating membrane. This translucent membrane serves to protect their eyes from dust, debris, and other foreign objects while still allowing them to see. Additionally, the haw plays a role in producing tears and spreading them over the surface of the eye, helping to keep it moist and healthy.

Dogs Can Sense Earth’s Magnetic Field

Believe it or not, dogs have a built-in compass! Research has shown that dogs possess a remarkable ability to sense the Earth’s magnetic field, allowing them to navigate their surroundings with precision. While the exact mechanisms behind this ability are still not fully understood, it’s clear that dogs rely on more than just their sense of smell and sight to find their way around.

They Have Unique Paw Preferences

Just as humans are either left- or right-handed, dogs also exhibit paw preferences, often referred to as being left-pawed or right-pawed. While most dogs are ambilateral, meaning they use both paws equally, some display a clear preference for one over the other. This preference can be observed in various activities, such as reaching for objects, digging, or even shaking paws with their humans.


As we celebrate National Dog Day, let’s take a moment to appreciate the extraordinary creatures that share our lives and homes. From their unparalleled sense of smell to their quirky behaviors, dogs continue to captivate and enchant us in ways both big and small. So, here’s to our furry friends – may their wagging tails and loyal hearts remind us of the joy they bring into our lives each and every day.
