When you have no one left who were dear to you and loved you, only the dog remains loyal. If the man did not have a dog, he would have found a way to create it. Why are humans and dogs so attached to each other? No other pet became such a friend to a man, as dogs did. Their whole life – is the owner. The dog will share happiness and sorrow, will always be happy to meet us at the front door and will never reproach their master and friend.
These days people bring dogs into their houses not only to guard, protect or hunt. Most modern dogs regardless of breed live with us "for the soul" and not to perform official duties. This is why it is extremely important to keep them mentally and physically healthy.
