This is the heartbreaking moment a loyal dog who had been searching for his missing owner was taken to grieve at his casket.

The Aspin dog named Chuchu had been with his owner Carlito Sembrano when he collapsed and was rushed to hospital in an ambulance.

Chuchu refused to go home when Carlito's family came to collect him and he stayed outside at the same spot in Tarlac City, the Philippines.

Tragically, Carlito died a few days later from the heart attack but loyal Chuchu continued waiting in the street for his return in the town of Capas.

Neighbours eventually decided to take Chuchu to the family home where Carlito was laying in his casket last Tuesday (September 10).

The heartbroken dog rested on his master's bike while looking sorrowfully at his best friend's body.

Neighbour Jessie Rodriguez said that Chuchu only went home after seeing his master's bike being used by one of their neighbours.

He said: "One time, Carlito's neighbour used the bike to bring him food. The dog recognised it and jumped on the bike after seeing it.

''Chuchu might have thought he was going to see Carlito again but that wasn't the case. We took him to the home where he was laying in rest. It was very sad when the dog saw his friend again. I could see that Chuchu was sad.''

Neighbours said that Chuchu and Carlito were inseparable, with the dog always tailing his owner wherever he went.

Even after Carlito had been rushed to the hospital, the dog refused to go home with his family when they came to collect him.

Instead, Chuchu went to the usual places he frequented with his owner every day and came back to sleep at the same spot at night that his best friend had been rushed away in an ambulance. Carlito's family would just bring over some food and water to him.

The dog is now being taken care of by Carlito's family.
