Why is dog INTELLIGENCE so inherited?

In the dog pack there is one of the most agile, the most intelligent dog, it is born athletic, I think only one dog can do it, that is the most talented dog - husky.
One day, I hurried home, my mother was dragging something, I hurried out, never thought it was a lovely husky, it was only six months old. In my home, I comfort it when it is sad, I feed it when it is hungry, under my careful care, it is growing up slowly, now it is eight months old.
