The role of dogs in humanity’s history

Dogs have been with us for a long time. In fact, they were the first domesticated animal, dating back to at least 15,000 years ago. Dogs have helped us in many ways throughout history, such as hunting, herding, guarding, and companionship. They have also influenced our culture, art, religion, and science. Dogs have been revered as gods, worshipped as ancestors, and honored as heroes. They have also been the subjects of many myths, legends, stories, and studies.

How dogs became domesticated

The exact origin of dog domestication is still a mystery, but there are several theories. One of the most popular ones is that wolves started to follow human hunters and scavenged from their leftovers. Over time, some of these wolves became more friendly and tolerant of humans, and humans started to select and breed them for desirable traits. Another theory is that humans actively captured and tamed wolf pups and raised them as pets. A third theory is that both scenarios happened independently in different regions of the world.

Facts of Dog #1: Dogs have an incredible sense of smell

One of the most amazing facts about dogs is their sense of smell. Dogs have up to 300 million olfactory receptors in their noses, compared to only about 6 million humans. This means that dogs can smell things that we can’t even imagine. For example, dogs can smell the difference between identical twins, detect explosives and drugs, and even sniff out cancer cells.

Dogs use their sense of smell for many purposes, such as finding food, tracking prey, communicating with other dogs, and identifying their owners. They can also use their sense of smell to detect emotions, such as fear, stress, and happiness.

Facts of Dog #2: Dogs can see in color

Many people think that dogs can only see in black and white, but this is not true. Dogs can actually see in color, but not as well as humans. Dogs have two types of color receptors in their eyes, called cones, while humans have three. This means that dogs can see shades of blue and yellow, but not red and green. Dogs also have better night vision than humans, because they have more rods, which are another type of light receptor in the eye.

Color vision is important for dogs because it helps them distinguish objects and signals in their environment. For example, dogs can use color cues to find toys, food, or other dogs. They can also respond to color signals from humans, such as traffic lights or clothing colors.

Facts of Dog #3: Dogs can understand human emotions

Another amazing fact about dogs is their ability to understand human emotions. Dogs can recognize facial expressions, vocal tones, body language, and gestures from humans and react accordingly. For example, dogs can tell when we are happy, sad, angry, or scared by looking at our faces or listening to our voices. They can also show empathy and comfort us when we are upset or stressed.

Dogs’ ability to understand human emotions is a result of their long history of co-evolution with us. Dogs have adapted to our social cues and learned to communicate with us effectively. This ability also strengthens the bond between dogs and humans and makes them more loyal and trustworthy.


Facts of Dog #4: Dogs can recognize up to 250 words and gestures

Dogs are not only good at understanding emotions, but also at learning language. Dogs can recognize up to 250 words and gestures from humans. This is comparable to the language skills of a two-year-old child. Some dogs can even learn more than that, such as Chaser the border collie who knows over 1,000 words.

Dogs learn language by associating words and gestures with objects, actions, or rewards. They can also learn by observing and imitating other dogs or humans. Dogs’ language abilities vary depending on their breed, age, training, and individual personality.

Facts of Dog #5: Dogs are incredibly loyal

One of the most admirable facts about dogs is their loyalty. Dogs are loyal to their owners because they see them as their family or pack members. They will protect them from danger, follow them everywhere, and stay by their side until the end. Dogs’ loyalty is a product of their evolution from wolves who live in social groups with strong bonds.

There are many examples of dogs’ loyalty in history and in the present. For instance, Hachiko, a Japanese Akita dog, waited for his owner at the train station every day for nine years after his owner’s death. Another example is Balto, a Siberian Husky who led a team of sled dogs to deliver life-saving medicine to a remote town in Alaska during a diphtheria outbreak. A more recent example is Capitán, a German Shepherd who stayed by his owner’s grave for six years in Argentina.

Dogs’ loyalty is not only beneficial for their owners, but also for their own well-being. Loyalty helps dogs feel secure, happy, and fulfilled. It also motivates them to learn and obey commands from their owners.

Facts of Dog #6: Dogs’ noses are unique like human fingerprints

Another amazing fact about dogs is their nose prints. Just like human fingerprints, dogs’ noses have unique patterns of ridges and creases that can be used to identify them. No two dogs have the same nose print, even if they are from the same breed or litter.

Dogs’ nose prints can be useful for identification and tracking purposes. For example, some dog registries use nose prints as a way of verifying a dog’s identity and pedigree. Some law enforcement agencies also use nose prints as evidence in criminal cases involving dogs.

Dogs’ nose prints have been used for identification since ancient times. In China, dog owners used to make ink impressions of their dogs’ noses on paper as a form of ownership proof. In Japan, dog owners used to carve wooden molds of their dogs’ noses and use them as seals.

Facts of Dog #7: Dogs’ brains have a “reward center” that responds to human touch

Dogs are not only loyal to their owners, but also love them deeply. This is because dogs’ brains have a “reward center” that releases chemicals such as oxytocin and dopamine when they interact with humans. These chemicals make dogs feel happy, relaxed, and bonded with their owners.

Dogs’ reward center is especially sensitive to human touch. Studies have shown that dogs’ brains light up when they are petted or cuddled by their owners. This is similar to how humans’ brains respond to affection from their loved ones.

Physical affection is important for dogs’ well-being because it helps them cope with stress, anxiety, and loneliness. It also improves their health by lowering their blood pressure, heart rate, and cortisol levels. Moreover, it strengthens the relationship between dogs and humans by increasing trust and cooperation.

Facts of Dog #8: Dogs have an exceptional memory

Dogs are not only good at learning languages, but also at remembering things. Dogs have an exceptional memory that allows them to recall events, places, people, and objects. Dogs have two types of memory: short-term memory and long-term memory.

Short-term memory is the ability to remember information for a few seconds or minutes. For example, dogs can remember where they buried a bone or where they left a toy. Dogs’ short-term memory is similar to humans’, but it can be affected by distractions or interference.

Long-term memory is the ability to remember information for days, months, or years. For example, dogs can remember their owners even after being separated for a long time. Dogs’ long-term memory is better than humans’, because they can store more information and retrieve it faster.

Dogs’ memory abilities are impressive compared to other animals. For instance, dogs can remember more than 1,000 objects by name, while chimpanzees can only remember about 20. Dogs can also remember complex sequences of events and actions, while rats can only remember simple ones.

Some examples of dogs’ incredible memory skills are Rico, a border collie who could remember the names of over 200 toys; Chaser, another border collie who could remember the names of over 1,000 toys; and Paddy, a Labrador retriever who could remember the route to his owner’s workplace after only one visit.

Facts of Dog #9: Dogs were the first domesticated animal

As we mentioned before, dogs were the first domesticated animals in human history. This means that they were the first animal that humans intentionally changed through selective breeding to suit their needs and preferences. The domestication of dogs had a huge impact on human society and culture throughout history.

The domestication of dogs helped humans in many ways, such as hunting, herding, guarding, and companionship. Dogs also helped humans explore new territories, trade with other civilizations, and fight in wars. Dogs also influenced human culture by inspiring art, literature, religion, and science.

The domestication of dogs also paved the way for other domesticated animals. After dogs, humans started to domesticate other animals, such as sheep, goats, pigs, cows, horses, and cats. These animals provided humans with food, clothing, transportation, and companionship. The domestication of animals also changed the environment, the economy, and the society of humans.

The domestication of dogs is one of the most important events in human history. It marked the beginning of a new relationship between humans and animals, based on mutual benefit and affection. It also showed the remarkable adaptability and intelligence of dogs, who can live in harmony with different cultures and climates.

Facts of Dog #10: Dogs can detect diseases in humans

Another amazing fact about dogs is their ability to detect diseases in humans. Dogs can use their sense of smell to identify changes in the body chemistry of humans that indicate the presence of a disease. Dogs can also use their sense of sight, hearing, and touch to notice signs of illness or distress in humans.

Some of the diseases that dogs can detect are cancer, diabetes, epilepsy, Parkinson’s disease, and COVID-19. Dogs can detect these diseases by smelling the breath, urine, sweat, saliva, or blood of humans. Dogs can also detect these diseases by observing the behavior, movement, or posture of humans.

Dogs’ ability to detect diseases has a great potential for medical fields. Dogs can help diagnose diseases early, monitor health conditions, alert medical staff or caregivers, and provide emotional support. Dogs can also help prevent diseases by encouraging physical activity and reducing stress.

Facts of Dog #11: Dogs can smell fear

The last amazing fact about dogs is their ability to smell fear. Dogs can smell fear because they can detect the hormones and pheromones that humans release when they are afraid. These chemicals are called adrenaline and cortisol, and they affect the scent of humans.

Dogs’ ability to smell fear has an impact on their behavior and well-being. For example, dogs can sense when their owners are nervous or anxious and try to comfort them or protect them. Dogs can also sense when strangers or other animals are fearful and react accordingly. Sometimes, dogs can become fearful themselves if they smell fear from others.

Dogs’ ability to smell fear is a result of their evolution from wolves who used this skill to hunt prey and avoid predators. It is also a result of their co-evolution with humans who used this skill to communicate emotions and intentions.
