Sheepdogs: Why are some UK dogs selling for £27,000 or more?
The humble sheepdog has been an integral part of British farm life for centuries, but never before have they commanded so much respect - or money.
The past two years has seen unprecedented prices recorded for specially bred and trained dogs at agricultural marts.
Many of the top dogs are now coming from Wales, including a border collie called Kim from Ceredigion, which sold for a world record £27,000 last February.
Sheep farmer and dog-handler Emrys Jones, from Barmouth in Gwynedd, said he regularly fields calls from across the world asking about his dogs, with 40 going abroad to places such as South Korea, Japan, Australia, Norway and the USA at a recent sale.
"The old boys wouldn't believe what's happening nowadays," he said.
Michael Priestley of Farmers Weekly said: "Better dogs cost more but better dogs make the job of gathering in sheep much quicker and they minimise labour cost.
"It's an investment that can pay off."
