A video of a German Shepherd named Alex has been circulating the internet for years.

The owners always kept him on a chain, which made the dog aggressive, but kind people helped him overcome his fear.

The video, which appeared on YouTube a few years ago, has already become a hit – to date, more than 6 million viewers have watched the rescue of Alex the German Shepherd.

The dog did not know freedom, therefore, when someone approached him, he always growled at them. Kind people came to the aid of the dog – at first they carefully removed the chain, and after 24 hours Alex became a completely different dog.

Watch the extraordinary transformation of Alex, the German Shepherd, who breaks free from the shackles of kind people and makes his life better. A scene that will surely warm your heart.
