A sweet pet dog comforted a grandmother when she fell to the floor after another naughty dog hit her.

The white pooch named Crispy was running around the yard with his German Shepherd friend Khai when the bigger creature rammed the old woman in Bangkok, Thailand, on January 7.

Crispy immediately stopped playing, apparently worried about the senior woman as he checked and hugged her.

Touching CCTV footage shows the fluffy dog cuddling around the 65-year-old, who tumbled to the floor.

Pet owner Chanya Thonglek said: ‘My mother was doing chores in the garden while the dogs were playing.

‘My dog Khai is really energetic and I know he didn't mean what happened. But Crispy was very sweet and affectionate.'

The grandma was not seriously hurt but suffered knee pains due to the fall.

The guilty pooch Khai was seen standing a few feet away from the pair before running up to the woman when she finally recovered.

Chanya said: ‘I scolded Khai after that. I was relieved my mother didn't break anything from the accident.'
