MANILA (UPDATE) - A stray dog, named Buboy, captured the heart of netizens as he continued to wait for the professor he came to perceive as his companion in Mabalacat City College, Pampanga.

But Buboy does not know that Professor Carmelito Marcelo, who took care of him for around 4 years, had passed away last May 18.

Buboy followed the professor everywhere on campus, according to Marcelo's colleague Kristina Demafelix.

"Kahit saan po magpunta si sir Marcelo nakasunod po si Buboy sa kanya. Pag nagkaklase po si sir Marcelo kasama po si Buboy, tas pag lunch time po binibigyan niya ng food si buboy," she told ABS-CBN News.

The faithful pup was brought to Marcelo's wake on Tuesday, the first time he saw his human since he fell ill and was placed in the hospital's intensive care unit for at least 2 weeks.

Demafelix said she decided to bring Buboy to the professor's wake after she noticed that the pup had been waiting for the professor outside their faculty room.

"Naawa po ako kay Buboy kasi nakita ko po siya na stress na kakahintay kay sir marcelo kahapon," she told ABS-CBN News.

"Ako po nag organize na dalin si Buboy kay sir para po kahit sa huling pagkakataon po makita niya si sir at maging aware po siya na wala na si sir Marcelo."

Demafelix said she will also bring Buboy to the funeral mass for Marcelo on Saturday.

The professor considered the pup as his child since he has no family of his own, according to Marcelo's sister-in-law.
