10 Unbelievable Facts You Probably Didn’t Know About Dogs

Dogs have been our most loyal companions, so it’s only natural that we always want to know more about them. So, if you see yourself as an experienced dog owner, then get prepared for these surprising and mind-blowing facts about our beloved canine companions!

#1 Dogs did not originate from wolves.

It's known that modern wolves are ancestors of dogs. But believe it or not, dogs originated from an entirely different species that disappeared thousands of years ago. 

Even though their DNA matches by 99%, modern American and European wolves are only very distant relatives of dogs.

#2 There is more than 360 dog breeds in the world.

There are a wide variety of dog breeds with different colors, sizes, shapes, fur, and physical characteristics. The sheer number of dog breeds is more massive than with any other mammal, domestic or wild.

Can you believe that there are almost 400 dog breeds in the world, and this is just the best guesstimate since it's continuously growing due to artificial selection? But, there is one limit to this variety, which is the physiology of a Chihuahua to Great Dane, cause they are descendants of ancient wolfs.

#3 Dogs have a second nose.

Did you know that dogs have a second nose? Well, they do. The second nose is known as the vomeronasal organ, also called Jacobson's Organ. 

The Jacobson's Organ is a "sense of smell" receptor that is not receptive to ordinary odors like the ones humans can sense. So, dogs have a double nose, one that's sensitive and another super-sensitive one.

#9 Dogs don’t feel guilty.

It is believed that wherever a naughty dog does something wrong, he will feel guilty. But it's been approved wrong; scientists prove that that look is just a natural reaction to the behavior of the owner at that moment. 

Guilt is a very complex emotion for a dog, and the dog fears to get into trouble. So, your pet learns that whenever he makes these "I'm so sorry" eyes, your heart melts.
