This video made my heart smile *big*

A mother dog is hit by a car, leaving her puppy alone and defenseless against the heat and the most dangerous highway. Rescuers spent hours trying to catch this little guy, who refused to leave his mom. When they finally captured the puppy, he growled and snarled and tried to bite. Rescuers feared the dog to be feral – and yet still never let hope leave their sight.

Just watch what happens next. This is a story about one puppy’s unconditional love.
