MANILA - A photo of a dying man's dog patiently waiting at the door of an emergency room in Davao City has gone viral on social media.

In his post, Alvin Ceria said the dog named "Saicy" followed its owner, Elenito Bandayanon, who was rushed by a neighbor to the Davao Doctors Hospital due to cardiac arrest.

Ceria, who is working for the Metro Davao Medical and Research Center, said the dog kept barking outside the ER as Badayon was fighting for his life.

"The dog was barking, it wanted to go inside the ER," said Ceria, who also revealed in the post that its owner eventually died.

"Sad to say the patient died. The dog's owner may have been dead, but the love of the dog remains," he added.

In a report by Sun Star Davao, Ceria said Saicy and the neighbor who rushed Bandayon to the hospital were allowed to enter the ER when the patient was pronounced dead.

He said Saicy touched his owner and howled.

During Bandayon's wake Saicy has been often seen on top of its owner's coffin.

According to family of the deceased, the dog has become weak because it hasn't been eating since its owner died on June 18.

Saicy has been tagged the "Hachiko" of Davao. "Hachiko" is the heartwarming story of a male Akita Inu dog, known for his remarkable loyalty to his owner. His story dates back to the 1920s when he was taken under the care of his master, Professor Hidesaburo Ueno.

The dog would arrive at the train station every day to wait for the return of his master from work. Even after Ueno died, Hachiko continued to wait for his master outside the station for some years until the dog passed away.

Hachiko’s story was passed on over generations and was even made into a movie starring Richard Gere as the dog's master
