Dogs: Information And Facts

Dogs / DogLet’s talk about man’s best friend ( and no, not your PC ). They look a little different in comparison to one another, but they are all examples of the human first pet. Here are some interesting facts about dogs.

Let’s start off by this, did you know that every dog breeds are related to wolves?

Even the Chihuahua is a relative to wolfs … ( We can’t believe it too. )

Well, around 15,000 years ago, humans lived alongside wolves. And in time, a few of these wolves became domesticated, meaning that they adapted from being wild to be able to live and even work with humans.
So, over thousands of years, a few of those wolves became the tamed dogs we know and love now!
Wild wolves still live in some places in the world today. But there are also more than 400 contrasting breeds of dogs! All of the wolves and dogs on the planet are thought to have originated from the same animal: a predator that walked our planet millions of years ago.
Scientist call it Eucyon davisi, and it looked a lot like current wolves, with one big difference: It was probably a lot bigger.

So if all wolves and dogs came from this previous predator, that means wolves and dogs are related!

Dogs are also related to other creatures that look a lot like them – including foxes, coyotes, and jackals. Together with wolves, these meat-eating mammals are called canines.

Here is an interesting dog fact for you guys:

There are no dog breeds that are overly-aggressive by birth. Thanks to movies, various breeds of dogs have gotten a lot of criticism over the years for having overly-aggressive personalities. With many people stating that it’s only in their nature to be so. A study, from the University of Cordoba, says that no breed of dog is dangerous by nature. It is all in the interactions with their owners. The most frequent signs of an aggressive dog are first-time owners, shortage of training, physical abuse and even not investing enough time with the dog. Indeed, certain dog breeds tend to be more dominant over others, but the scientists say that this factor has a minimal effect on the main behavior, compared to the impact that human interaction has.


Dog’s intelligence is the equal of a 2-year old human.


When a dog chases its own tail or drops a present on your new carpet ( even though you just took him or her for a walk ) we question if they have a brain to at all.  Well, they do ( surprise ) and may be brighter than we thought – according to Stanley Coren at the University of British Columbia. He stated that intelligence varies between breeds, but the ordinary dog can learn up to 165 words, count up to 5 and even display signs of understanding basic arithmetic. They can even intentionally trick other dogs or people if they have the right motivation. The most intelligent dogs can get up to 250 words and if you’re curious – Border Collies are the sharpest of them all. Although this level of intelligence is approximately equal to the average two-year-old human.

For those of you that say “My dog knows when I’m upset! ” you guys may not be just annoying to the rest of the world, but also right. 😉

A 2015 study unveil, that dogs have the ability to recognize between different emotional expressions. The study claims that this makes dogs the first scientifically valid species, outside of humans, to recognize emotions on species other than their own. The canines were shown the upper and lower halves of a face, and they were able to accurately identify the emotion more often than what was expected from random guessing, while also showing their recognition of different emotions in humans.


Speaking of abilities …


Speaking of abilities, don’t forget those charming puppy eyes, that you can’t say no to.

Japanese scientists say, that they’ve studied the reason we can’t resist them. Gazing into them causes a rise in the hormone Oxytocin, occasionally called “the love hormone”. It is the chemical in the brain that, when released stimulates people to bond with each other, most notably parents and their children. What’s intriguing about this new study according to NBC is that it confirms the level of oxytocin increase in both humans and the animals. Previously believed that the hormone only rose in humans.

The Japanese team supervised several experiments to come to that result.
In the first test, they had 30 dogs and their keepers in a room for 30 minutes. After that, they gathered urine samples from them both. Those, with the bigger levels of the hormone in their urine, had actually looked at each other for a substantial period of time. Which the New York Times said the researchers defined as “100 seconds in the first five minutes of the encounter.”

In the following test, researchers used a nasal spray to give the dogs some additional boost of the hormone. It was discovered that the female dogs gazed at their owners for a longer period of time than the male dogs. Ensuring a hormone increase in female dogs owners. While the study did not have an explanation for why the female dogs looked longer than the male gods in that second test, the scientists do believe that when dogs become domesticated they in some way learn the ability to love. That theory was further cemented when the same experiments were done on a set of wolves and their handlers.

Wolfs couldn’t keep the gaze.

“Evolution is a tinkerer … and when humans and dogs came up with this indeed stranger, more unique relationship, it looks like oxytocin got entangled for that as well.” – Stanford University neurobiologist told the Los Angeles Times.

But not everyone agrees with this newly discovered connection. A psychologist from Arizona State University states, that oxytocin can also be linked with feelings of emotional isolation and aggression in animals.

Still, more research is needed on this topic … so moving on then.


Super-smellers!


Now, another cool thing about our furry friends is that they are super-smellers!

Their delicate noses have 40 times more cells in them for smelling than ours do – plus they have the talent to wiggle their noses in ways that we can’t! ( Because you can’t survive without that wiggle wiggle … we all know that wasn’t funny, but we had to try. )

By wiggling each nostril separately, dogs can determine which direction a smell is coming from. So, when they’re born, puppies can’t hear or see anything, but they swiftly learn to find their mother ( and other important things in the world around them ) just by using their nose.

Lots of canines put their powerful sense of smell to use in other ways.

Some dogs can sniff out and find people who are lost, some hunt for escaped criminals, they are even put in the military fighting alongside humans.
With the many professions that Lassie have, just to put this in there, a few of them are even trained to sniff out deadly illnesses.

Scent dogs are being used to identify thyroid cancer by smelling urine samples. Their results are equal to, or only a little below, the fine needle aspiration biopsy – the present method of detection. They are correctly able to recognize the difference between cancer and another disease 88,2% of the time. Identical results have also been shown for dogs finding prostate cancer. Some of our furry friends can even smell seizures. With many epileptics stating that their dog can accurately predict a seizure anywhere from 30 seconds to 45 minutes ahead of time.

In the end, dogs are one of the most loyal, to us humans, creatures on this planet. They stood by us for centuries, helping us, cheering us up. We can proudly say that they earned the title of “man’s best friend” because they are.
