An amusing video of a confused rescue dog spotting himself in a mirror and attacking his reflection.

The footage, filmed in the Philippines in January, shows the former street dog, called Killer, chowing down on a bowl of food before he notices his reflection and begins attacking the mirror.

There's an uplifting story behind the dog too.

"Killer was an abandoned street dog," the filmer explained online.

"He was nothing but fur and bones, I saw him on a rainy night and he looked like he was about seven months old."

"I befriended him and named him 'Killer' because he defends my yard and his food with a ferocious attitude," he continued.

"Due to his upbringing he is very possessive over a food source so I decided to set a mirror in front of his food to see his reaction.

"You can see the food came first and dealing with the intruder came second.

"Killer is a sweetheart [to me] and is very loyal."

"Killer" was an abandoned street dog. He was nothing but fur and bones. I saw him on a rainy night and he looked like he was about 7 months old. He ran past me and hid under the house trembling. Street dogs in the Philippines are basic scavengers and get no love or attention from humans. Most are leary of people due to this abuse. I befriended him and named him "Killer" because he defends my yard and his food with a ferocious attitude. Due to his upbringing he is very possessive over a food source so I decided to set a mirror in front of his food to see his reaction.
You can see the food came first and dealing with the intrude came second! As soon as he is finished and the intruder can not take anything he is now ready to attack and that is the funny part. Killer is a sweetheart [to me] and is very loyal.
