But the pattern repeated night after night, and the man became a bit confused and little concerned. That’s when he decided to dig into the dog’s past and learn about his history.

And then he came across the heartbreaking truth — the dog’s previous owner had waited for him to fall asleep one night to quietly drop him off and abandon him at the shelter.
