That's why the dog is really man's best friend – video

What we have always known is now proven by a study: Hardly any other animal is as good a friend to humans as the dog – as the scientists explain, you can find out in the video.

They are happy every day when the owner or mistress comes home and also for the owner, the stress of the day is blown away when they are finished and their dog greets them with a wagging tail and rushes wildly towards them. No wonder that the dog is said to be man's best friend. And a study now shows that this is not only a popular saying, but also has a scientific background. You can find out the results of the study in the video.
