In a short clip uploaded to Imgur the girl, wearing a purple top, can be seen sitting on her sofa.
A small black dog sits quietly in front of her, with his back to her.
Deciding to bother the dog, the girl blows hard on the back of his head.
He turns around, and she grins at having got his attention. But she quickly regrets her actions as the dog reacts in a surprising way.
The little dog looks at her for a few seconds before deciding he isn’t happy.
He then lifts his paw and slaps the girl in the face.
Her head moves to the right and the smile disappears from her face.
The clip has gone viral online, with over 277,000 views.
One commenter wrote: “People are terrible, and I hate them.”
Another said: “Can’t we all just get along? No? Oh, okay.”
One person said: “Sweet, sweet justice.”
And one wrote simply: “This pleases me.”
This is not the first time a dog has had revenge – video footage showing a man trying to kick a stray dog has gone viral after he suffered immediate karma.
A man enjoying a fun evening on the beach with friends spotted a stray dog in the distance and decided to liven up the night’s events by tormenting the pooch.
The dog was minding its own business when the man decided to strike.
While his friends waited sat down, the man sprinted towards the canine and looked as though he was ready to kick it – but then something amazing happened.
