This is the heartbreaking moment a grieving mother dog made a grave to bury her dead puppy.

Footage shows the heartbroken pooch named Bettie scraping the hole with her front paws before dropping the lifeless puppy in it and covering it with soil.

Lenny Rose Ellema recorded the affectionate dog digging the grave in their backyard in Pangasinan province, the Philippines on September 15.

The sad pet owner said the four-year-old dog had lost puppies in a previous litter and had shown the same maternal instincts to take care of them, even though they were dead.

She said: "We did not train her to do it. We were amazed when she first did that last year with another puppy. She is a special dog."

Lenny added that before Bettie buried the dead puppy in the video, it tried to "revive" it by trying to breastfeed its mouth.

She said: "I would try to take the puppy away but she would not let me so I left them there until she was ready to bury it."

Lenny said the grieving dog give up trying to revive her baby after a few hours then buried it in the ground.

However, Lenny said the dog returned to her usual happy self after a few days and take care of her remaining puppies.
