Sheepdogs are trained to obey their master's every word. So when farmer David Kennard decided one of those words would be "Spring", his dogs did not hesitate.
They rounded up the flock on the hills of Mr Kennard's north Devon farm and, with a little help from their master, created a picture that reminds us that, whatever the weather, this is officially the first weekend of Spring.
The scene did call for a careful scattering of feed to make the sheep form themselves in the shapes of the six letters.
It may be snowing elsewhere in Britain, but if these sheep say it's spring, it's spring
However, it was down to the team of Collies – who everyone knows border on the brilliant – to have the last word. They circled the 200-strong flock and kept them from wandering off-message.
Three of David's five working dogs – Mist, Fern and Jake – were employed to help create the perfect lettering, which took three hours to achieve.
Said David yesterday: "I'm proud of my dogs. They couldn't have done it without my spreading the feed across the hillside, of course – but I couldn't have done it without them, either."
But then David's Border Collies are very much of the performing breed. They have appeared on DVDs and on TV in films made by the 41-year-old farmer.
He originally started making videos of his hard-working hands ten years ago to supplement earnings at his 400-acre farm near Woolacombe. He then wrote a top-ten best-selling book, A Shepherd's Watch.
The sheep were herded into position by the faithful - and now famous - sheepdogs
That led to a TV film which followed the progress of one particular dog, Mist, from puppyhood to full-grown sheepdog. Other starring roles were taken by Mist's mother Gail, grandparents Greg and Swift and fellow four-legged family members Ernie, Fern and Jake.
The film proved so successful that Mist's adventures were turned into a channel Five children's TV series with the voices of Derek Jacobi, Brian Blessed and Sandra Dickinson.
"It all started when I noticed people leaning over the walls of my fields to watch my sheepdogs at work," David said. "I realised my dogs were my greatest asset and that if One Man and His Dog was so popular, I ought to give it a go."
David placed his first video on local farmers' market stalls – but it ended up selling 80,000 copies worldwide. His TV series, Mist: Sheepdog Tales, returns with a new series on Five next month (April 12), along with a newly-released DVD (April 14) of the entire first series.
As well as going above the call of duty to earn their keep, David's dogs are very much part of the family, sharing kitchen space with his wife Debbie and their three children.
But when it came to getting sheep to put a spring in their step, they proved they could conjure up a bright spell, whatever the Easter weather.
