This Heartwarming Reunion Between a Boy and His Missing Dog Has Us in Tears

As an only child who considers my dog my "brother," I cannot even begin to imagine what it would be like for my four-legged partner in crime to go missing. For one little boy in Lubbock, TX, that nightmare situation became a reality when his dog Kase went missing last month. Luckily, this story ends in the best possible way — Kase was found with a family that lives right down the street by the boy's mother, Paula Williams.

Williams decided to surprise her heartbroken son and film the reunion — the video posted to Facebook has nearly four million views — and what ensued is the sweetest thing you'll see all day.
