It is hard to imagine a world without dogs. This adorable species has accompanied mankind for millennia. The noble conditions that dogs possess have made them inseparable friends of human beings. In fact, for many people who own dogs, they become a member of the family. In this article we have prepared a series of things you didn’t know about dogs. Read on to find out what they are.

Things you didn’t know about dogs

1. Nose

The dog’s nose is unique and has about 300 million olfactory receptors. This characteristic gives them an ability to detect odors far superior to that of humans. Some dogs are trained to detect odors that can inform about the presence of diseases in humans. In addition, a dog’s nose is equivalent to a person’s fingerprint: no two dog noses are the same.

2. Ear

The hearing of dogs is also another sense that is highly developed in this species. Dogs have the ability to detect sounds that are very far away, very low and at a much higher frequency than the human ear allows. For example, humans can hear frequencies up to 20,000 Hz, while a dog can hear frequencies up to 65,000 Hz.

3. Third eyelid

Dogs have a lower eyelid and an upper eyelid, just like humans. But unlike these, they have a third eyelid located at the inner corner of the eye. This third eyelid acts as a protector of the eye and keeps it moist. It is also capable of protecting this organ during a fight.

4. Nightmares

It has been proven that dogs are capable of having happy dreams as well as nightmares. Research has determined that dogs have deep REM sleep cycles, just like humans. It is likely that while dreaming, they recreate the experiences lived during the day. There is even speculation that they may dream of their human masters.

5. Emotions

A dog may suffer from some emotional disorders such as anxiety or depression. Factors such as the loss of its owner, environmental stress or lack of socialization can cause emotional disorders to the dog. Be aware of your dog’s behavioral changes and seek professional help in case of these symptoms.

6. Personality

While there are general character traits that the vast majority of dogs may have, it is also true that each dog may have its own personality traits. For example, a dog can be playful, territorial, energetic, protective, shy, among other traits. Sometimes a dog’s character can be influenced by early socialization and other factors such as the environment.


In addition to all these incredible things you didn’t know about your dog, we learned that the first breed of dog originated more than four thousand years ago in the Middle East. This is the Saluki, a type of hunting dog. Records of this species of dog have been found in tombs dating back more than 2,000 years BC.
