This is the impressive moment a helpful pet dog delivered fruit to a grandmother's house.

Owner Pop Anawut has trained Thor, his three-year-old pooch, to carry freshly harvested pomelo into the elderly woman's home.

Footage shows the pet owner placing the green, spherical fruit into a plastic bag before tying it to the canine's red vest, along with a bottle of soda, on November 30.

He then commanded Thor to go out, prompting the energetic animal to sprint across the street, causing the bottle to fall onto the ground.

It then arrived at Pop's grandmother's house, just a few yards from its home in Tak province, Thailand.

The pomelo can be seen rolling on the concrete floor in the garage while the family sitting outside giggles at the dog's behaviour.
