Do you know that dogs smile

Do you know many things about dogs called man's most loyal friends?

Zoologist and anthropologist John Bradshaw studies the interactions and interactions between humans and animals.

John Bradshaw, author of the books In Writing of Dogs and Diff Animals Among Us, has also made a deep study of the history of dogs so far.

Know from him 10 such things related to a man's firm and loving friend, whom you may not be aware of:

1. Distance of wolves

Dogs are distant characters of that breed of wolves that went extinct thousands of years ago. The wolves found today in the United States and Europe are distant relatives of dogs. The DNA of these wolves matches 99 percent of the DNA of dogs.

2. Overly parallel too parallel

Dogs have many sizes and many breeds. Such lovely people are not of any wild or domineering animal. Human is alive for this too.

However, there is also a limit to the physical diversity of dogs.

From the smallest chivava to the largest dog Great Dane, the anatomy remains on the same structure as his ancestral wolves. Even though everyone has different sizes and breeds, there are also similarities.

3. Why smelling faster?

In dogs, the ability to smell is a part of an organ called Jacobson or vomeronaseal that is on their nostrils and upper part of the mouth.

Scientists are not yet aware why it is this organ. Studies on crocodiles and other animals suggest that they probably have this ability so they can identify the precursors left by other dogs.

4. Dogs Think that Cai

Have you ever come to mind what dogs look like?

Dogs can distinguish green, yellow and blue like we do, but their eyes cannot catch red.

The dogs have a darker gray color.

5. Dogs Smile

Dogs smile but not for the reasons that we humans smile.

Biologist John Bradshaw explains that the dog smiles to get a little love from its owner.

So if they are not smiling, we think they are happy. This can be a sign that they are a bit restless and you need some pain or courage.

So whenever you see your dog smiling, do not show it to him.

6. There is no fatwa

Dogs do not feel that they have done something wrong. However we may feel when they make a face like shame.

A lot of people explain how their dog gives a 'gilty look'. Gender science suggests that dogs respond at the time based on the body language of the man standing in front of them.

Guilt is a tricky emotion that dogs cannot understand. In such a situation, dogs give a gilt look but are scared that they can be punished. But they do not realize that they have done something wrong.

He said that the government has taken several steps to prevent such incidents.

7. Must be supported

Once the puppy learns that the nature of humans is favorable, his natural knowledge tells him that he is more likely to live with this person.

This is why many dogs get upset when they are left alone. They cannot think far and may feel as if the owner has left them forever.

8. That's why dogs are friendly

According to National Geographic, living with humans only produces an ultra as Williams syndrome in dogs.

If humans do not have genes named GTF2I and GTF2IRD1, they become Williams Ultra. This is a situation in which people find it difficult to understand and they get 'used to love the whole world'.

If seen in dogs, their genes named GTF2I and GTF2IRD1 are different. This is why they become more friendly by coming into contact with humans.

9. Keeping feelings for humans

Many mammalian creatures feel basic expressions of love, fear, restlessness and happiness. But it has been learned that dogs give different types of statistics to humans.

Many people think their dogs love them. Now scientists have found that the behavior of dogs depends on how much they love someone.

Professor Gregory Burns of Emery University trained the dogs to stand still during the MRI. To see how his brain responds to the joy of seeing the owner's photos.

It was found that dogs understand human body language better than chimpanzees.

10. Wild inside

If a dog does not come in contact with a person in three months for the owners of his life, then he can remain wild.

An example of this is a dog named Typian Dingo, which was domesticated until about 4000 years ago. But these dogs, left alone on this island, have now become wild.
