In a tale that could rival Japan's legendary Hachiko, another dog in Chennai, Tamil Nadu, displayed the same endearing loyalty to its owner.
While Hachiko waited at the same train station for years even after its owner had died, the late Bhaskar's brown mongrel sat at the teenager's grave for more than a fortnight, reported Malaysia Nanban.
The 18-year-old boy died in a road accident and the dog he had adopted sat by his grave, refusing to eat and braving the sun and rain.
Blue Cross of India volunteers spotted the dog at the open burial ground near Avadi Bridge.
When they tried to take the dog away, it refused to budge, pawing the grave and whining.
After some inquiries, the volunteers found out about Bhaskar, and later managed to locate his mother, Sundhari.
The 50-year-old construction worker said the dog, Tommy, was her son's pet for five years. "It disappeared after Bhaskar died," she said.
Sundhari, a widow, said life became meaningless after the death of her only son. "However, Tommy's undying affection for Bhaskar gave me the impetus to move on."
