If you think that you know absolutely everything about dogs, think again. Even though dogs have been living around us for a very long time, you might still find something surprising in this article. For example, did you know that a dog’s nose is not just sensitive to smell, it’s so unique and multi-functional that we can probably call it a built-in mini-computer?

We at Bright Side want to share some interesting facts with our readers and this is why we prepared this selection for you.

1. Dogs did not originate from wolves.

Owners often say that their dogs learn to pretend to be sick or injured to get more attention. They are very quick learners after all.

6. Dogs can recognize colors.

It has been believed for many years that dogs see everything in black & white. Actually, dogs can see some colors, but not nearly as many as us. They see green, yellow, and blue colors, but they’re not able to recognize red, which they see as dark grey.

7. Dogs can smile.

Most of the time a puppy’s instincts tell him that the best way to survive is to be near a human, usually their owner. That is why many dogs feel very unsettled when they are left alone at home: at that moment it seems to them that they have been abandoned forever and no one will take care of them anymore.

12. Dogs are very attached to people.

Many mammals are capable of experiencing emotions, like love, fear, and anxiety, but dogs are known for expressing more emotions than any other animal. In addition, dogs understand human body language and their tone of voice.
