After living and working in Slovenia for two years, Rebecca Ehalt returned home to Pennsylvania in July 2014 and shared a touching video of her reunion with the family dog. In the clip, Rebecca is greeted by the schnauzer - named Casey - who lets out a lot of high-pitched whimpers before passing out, as Rebecca describes it, "from overwhelming joy." Not only is Casey's reaction insanely adorable, but it's also totally understandable since Rebecca's two-year absence has been over a decade in dog years. Even though the video isn't exactly new, it's easy to see why it continues to go viral. Watch the sweet reunion video now.
