Sally Steiner posted the clip of her son Ollie trying to use his sheep Dotty as a horse. The family live in New Zealand and have had the pet sheep since they were baby lambs.
Sally told Buzzfeed that she was surprised to find out her sons had been riding their pets.
She said: “I had heard some screaming and laughing the night before and asked the boys what they were up to - they said they were riding the sheep - I thought maybe they might have been trying to - but probably not successfully."
