The dog is one of the animals that has lived side by side with humans for thousands of years: it is believed that the relationship began in the Neolithic period.
The role of the dog changed with the times.
Previously, the dog was only a guard and assistant, but now he has become a real member of the family.
What facts about dogs are known only to intellectuals
Origin from wolves
For quite a long period of time, there has been a stereotype that the ancestors of our pets were once members of a wolf pack.
This is a misconception.
As it turns out, the ancestor of dogs was indeed a wolf, but it disappeared several thousand years ago.
Dogs can distinguish colors
Many people are sure that dogs are animals that are unable to see the difference in colors. This is a mistake. The only difficulty is the red shade, which seems gray to them.
Optimism and pessimism
This fact surprised even scientists, but it is an established fact. Dogs are also divided into optimistic and pessimistic.
This largely determines their character.
