There isn’t a love much stronger than that of a dog. It’s an unconditional love, a joyful love, a pure love. Dogs don’t qualify their emotions the way many people do; there are no strings attached. Except maybe making sure the bowl is full of kibble on a regular basis. But they’ll easily forgive you if you forget once in a while.
That love doesn’t dwindle or die, even if, like the man in this video, you’ve been absent for three years. This dog’s reaction goes from surprise to sheer, unbridled happiness so fast you won’t have time to blink.
