A border collie has become the most expensive sheep dog to be sold at auction.
Lynwood Cassie, known as Cass, was bought by Herefordshire farmer Paul Evans for £3,300 at Skipton Market in North Yorkshire.
Jeremy Eaton, the auctioneer who sold Cass, said good dogs at the better end of the market regularly sold for between £1,500 and £2,500, but Cass was the first working dog to be sold for such a high price.
He said the one-year-old dog was special because of her skilful handling of the sheep at such an early age.
"To have a dog perform a trial like that at that age is quite exceptional.
It would take a professional shepherd up to six months to get a dog up to speed - so someone has been saved all that hassle

"It requires people to spend an awful lot of time to get dogs to that level," he said.
"She can already out-perform older, more experienced dogs."
Cass will now work with six other dogs and a flock of 2,000 sheep on the farm in Ross-on-Wye.
Phil Buckley, from the Kennel Club, said a fully-trained sheep dog ready to go straight into the fields would be worth its weight in gold to a busy shepherd.
"It would take a professional shepherd up to six months to get a dog up to speed so someone has been saved all that hassle and the dog can go straight into the field and work the sheep," he said.
