Canelo

Canelo the dog lived on the streets of Cadiz, Spain, with the man who loved him. Canelo didn't regularly have a roof over his head, but he loved his human more than anything. The man went to the hospital for dialysis treatment every week, where Canelo wasn't allowed inside. But he would patiently wait by the door for hours, which seemed like forever to the dog, because he knew his human would eventually come back outside. Until the day he didn't.

You might have to grab another hankie when you learn that this is a true story. It happened about thirty years ago, and people from Andalusia are very familiar with it. Canelo spent years waiting outside the hospital, escaped from the pound twice, and refused to stay with families who wanted to adopt him. After his death, the street that ran in front of he hospital was renamed in the dog's honor. (via Nag on the Lake)
