This is one of the cutest heartwarming stories you’ll ever find. Ed Gernon from California recently adopted a shelter dog named Rex. Rex’s rough street life had earned him a very feral and dangerous reputation.

One day, Rex found a tiny, sickly hummingbird, dying in the garden, and his tough heart melted then and there. The bird had no feathers, and ants were feeding on her lifeless body. Rex coaxed Ed to check on her and bring her in.

Together, Ed and Rex nursed the bird back to health. Ed was amazed to see his fierce pet protect the bird so passionately. After days of care, the wee birdie miraculously started to recover and soon, she was fit enough to fly again.
