Touched by seeing the dog, Sardella, a lawyer from the town of Novo Horizonte, decided to ask the hospital receptionist about him. That's when she came to know his heartbreaking story.
The dog belonged to a homeless man who, four months earlier, had been stabbed in a local park. After an ambulance came to pick the man up and rush him to the hospital, the dog chased after. When the man was wheeled inside, the dog settled down at the front door to wait for him to come back out again.
Thus, the dog's long vigil began.
