Here is a video of a dog welcoming home his owner who came back for the first time in two years.
Both the owner and the dog appear to be quite emotional and the welcoming is heartfelt on both sides!
  

Before his master has come back, the dog is very excited before the door is opened!!

As soon as the door opens, the welcome home begins!

  
This is a wonderful welcome back home the first time in two years event! I think that the owner is just as happy as his dog to be finally home!!

That was exciting to see!
