Interesting facts about dog's Abilities

1. A wet nose aids its sense of smell 

Aside from helping keep a dog cool, its wet nose aids the dog's sense of smell as scent particles stay longer on damp surfaces. The dog licks its nose to identify the scent better, gathering the scent on its tongue and placing it in its mouth. Inside the mouth is a unique organ called the Jacobsen's organ, which improves the dog's smelling power, allowing it to smell 1000 times or more than a person.

2. How old are dogs in human years?

The general computation most people have in mind is that one dog year is equal to seven human years. Scientists have discovered a different, descending scale: 15 human years is equivalent to the first dog year (medium-sized dog); 9 years for the second dog year; and roughly five human years for each dog year after. Generally, smaller dogs age slower than bigger ones.

3. Sweating through their paws

Although dogs pant to keep themselves cool, they have another way to reduce their body temperature: sweating through their feet. That's why you might notice wet paw prints on a sweltering day whenever your dog walks around.

4. The myth that dogs are color blind is not true!

For many years, many believed that dogs could only see in black, white, and grey. However, researchers have discovered that they can see in color, just not in the same spectrum as most people. Blues and yellows are more vivid in a dog's eyes than reds or greens, which is something to consider when buying your dog something to play with.

5. A dog's identification

If people have unique fingerprints, dogs have unique noses. Some technology experts have even developed a phone app that can recognize and store a dog's "nose print" so that a lost canine can be reunited with its owner.

6. Feet like chips

Have you ever noticed the corn chip smell from your dog's feet? It's a natural smell produced by the bacteria on their feet as well as the sweat from their paw pads. But should their feet become extra smelly, that may be a sign that something is wrong with your dog's feet.

7. Choosing between north and south

Researchers in Germany have documented that dogs do their "business" (pooping and peeing) while facing either the north or south poles, provided that the magnetic field is "calm." Other than that, researchers are still unsure of how dogs use this particular sense.

8. Smelling how you feel

Many dog owners love the fact that their "best friend" can notice if they are happy, angry, or blue. One study shows, however, seemingly shows that dogs can smell these emotions based on their reaction to human sweat that was gathered after a human volunteer watched a particular video. The smell of a sweat from a scary video raised the dog's heart rate more than sweat from a happy video. One of the most friendly dog breeds is the Golden Retrievers.

9. How smart is your dog

Researchers believe that dogs have the intelligence of a toddler (2 - 2.5 years old). While they might not be able to conquer the world with such IQ, they are able to comprehend more than 150 words, solve problems in their environment, and follow some commands.

10. They love drinking water

Even though a dog can smell a thousand times more than a person, its sense of taste is not as refined as it only has 1700 taste buds compared to a person's 9000 taste buds. Despite this, its taste palate is different than ours as dogs really love the taste of water. Scientists think it is nature's way of keeping them hydrated as meat can be quite salty.

11. Acute hearing

The human hearing range is 64 to 23,000 hertz. The dog's range is from 67 to 45,000 hertz, meaning they can pick up high-frequency sounds. Dogs with perked ears often have better hearing than dogs with floppy ears.

Strange but True Historical Dogs Fun Facts


12. Origin of domesticated dogs

According to scientists, all dogs originated from an ancient wolf species, eventually becoming "dogs" some 15 thousand to 40 thousand years back. While scientists agree that prehistoric men somehow domesticated them, one other theory is that dogs may have domesticated themselves. Learning that they can share in man's goodies, some researchers think there may have been a "race" among dog breeds to become friendlier to humans, which is why we have such a variety of dogs today.

13. First known dog

A group of researchers has identified the remains of the earliest known dog in Belgium, dated to have lived 31,700 years ago. After analyzing its skeleton, they think it may have looked like a much larger Siberian husky version. The next oldest remains of a dog lived 14,000 years ago in Russia.

14. The spiked dog collar

Researchers think that collars' use began with ancient royalty, who may have designed this accessory to show their standing in society.

This was to protect the neck of their canine friend from wolves that regularly attacked the livestock and any other animal that got in its way.

15. Anti-tank dogs

War makes people come up with "crazy" yet sad plans for animals. After World War One, the Soviet Union began training dogs to carry a bomb towards a tank, where the bomb would detonate in several possible ways. Thankfully, this method of attacking the enemy did not work so well in the actual battle for the dogs, greatly reducing the need for a suicide bomber dog.

16. Dogs on the Titanic

When we think about the Titanic sinking, we usually remember the many people who died and those who miraculously survived. But it turns out that 12 dogs were onboard that ill-fated ship, of which 3 were able to survive: a Pekinese and two Pomeranians. Perhaps because of their small size, nobody complained about having them in the lifeboat.

17. First dog in space

Before humans ever entered outer space, Laika, the dog, made it there in 1957, riding the Soviet Union's satellite Sputnik 2. Sadly, the satellite's internal environment wasn't equipped well, so Laika probably didn't live very long in space. In 1960, a more successful venture in space occurred where the animal crew safely returned home.

18. The notorious Pete of President Theodore Roosevelt

President Roosevelt had a family pet that he loved so much, Pete, the bulldog. But Pete had taken to nipping people he didn't like, becoming a nuisance to some visitors at the White House. But such incidences were often brushed aside by the President until Pete attacked the French Ambassador, which finally forced President Roosevelt to send Pete out of the White House.

The dog was an important part of ancient Egyptian life, serving as guardians, pets, cattle herders, and even as a part of their religion. Anubis, an Egyptian god of the dead, is shaped as a Basenji (a type of hunting dog in Africa). In the temple of Anubis, dogs roamed freely.

Crazy Fun Facts about the Dog's Behavior


21. Stray dogs riding in subways

In Moscow, Russia, living on the cold streets can be tough, which is why some of the city's stray dogs have learned how to live or at least navigate their way through Moscow's subways. Citizens have gotten used to seeing a stray dog riding the subway by itself. Also, dogs curl at the feet of passengers to get warm. That's a day in the life of a street dog in such cold places.

22. Eating poop

You might have noticed that your dog may sometimes eat poop. This behavior is considered "normal" if it's a mommy dog eating the young puppies' poop or a dog eating the poop of other kinds of animals (apparently for possible nutrients in other animals' poop). But if your dog is eating its poop or the poop of other dogs, something is probably wrong psychologically or physiologically - so do investigate.

23. Smelling each other's butts

A common sight when dogs meet is for each dog to smell one another's butt. It turns out that dogs secrete a unique smell from their anal glands, which can help a dog determine if they have met before. The smell also allows a dog to assess if this new visitor is a threat.

24. They sneeze when they play

A dog sneezes for the same reasons why a person sneezes: something irritated its nose. But behavioral experts say that when playing together, a dog also sneezes to inform its playmate that it is just having fun, especially if things start to get rough.

25. Dogs have dreams and nightmares too

By doing sleep experiments, researchers have found that dogs do dream. If it is a happy one, as discovered in experiments, the dog was able to move while asleep and does things it likes to do. But a dog can also have nightmares, which is why it may be snarling while asleep - so be careful NOT to wake it up because you don't know how it may react.

26. Tail wagging

Although they bark and growl, dogs generally communicate through body language such as tail wagging. While many of us know dogs wag their tails to show happiness, they also do so to communicate aggression, fear, submission, negotiation, and curiosity. And since it is a form of communication, should you ever video your dog in secret, you will see they don't wag their tails when alone.

27. Dogs love to lick

For a dog, licking gives them much pleasure as it releases endorphins. But when a dog licks a person, it is often a sign of affection for its owner. It may also mean they love the salty taste of your skin.

33. Arson dogs

Another type of police dog that is in a category of its own in this article is the arson dog, which is trained to sniff out chemicals used in arsons.
