British supermarket Tesco has ordered its largest suppliers in New Zealand, Silver Fern Farms in Fairton, Canterbury to stop using dogs to herd sheep into the abattoir. Tesco wants the shepherds to wave their arms, beat sticks or wave flags, to move the sheep into the abattoir. The surprise order from Tesco, which comes into force next week, came to light thanks to a letter sent to the Daily Telegraph by an upset reader. Mick Petheram, one of the shepherds, said: “New Zealand sheep are used to dogs, they know dogs. There’s more stress in a human herding and manhandling them, waving their arms and beating sticks. Dogs are part of a sheep’s life. This is absolute baloney.” Tesco stood by its decision. “We don’t have a problem with sheep dogs, but we need to make sure they move the sheep in a considerate manner, so they don’t stress the sheep out,” said a spokesman.
