S! TV VIRAL: Dog’s reaction to long-lost owner will amaze you!

This is so amazingly cute, then it gets a bit scary, then it's super cute again! 

When this family member arrives home after being away for two years, she got the best reaction EVER from her pet dog!

As he sequels in delight, things get a little serious as he appears to pass out from excitement, but it all ends well, thankfully!

We're almost certain that's a smile we see at the end…
