The International Sheepdog Society’s supreme championship trial, held at Shandford Farm near Brechin, was won by Kevin Evans, from Wales, with Hybeck Blake.
Additionally, on Saturday, partnered by Derwen Doug and Knockmaa Bec, Kevin won the brace championship.
The combination of supreme and brace championships was last won by one person in 1972, when John Templeton of Fenwick, Ayrshire achieved the two accolades.
Mr Evans is no stranger to success and this is his fourth time winning the supreme championship, having previously won twice in Wales and once in Ireland.
To win this year’s championship, Blake ran out 800 yards to lift 10 Texel cross ewes waiting out on the left, lifted them and fetched them back though a gate and left them to seek more.
He repeated the exercise, running out to the right hand side of the hill for more sheep, which he duly fetched back through a further gate to unite the two lots.
The packet was then driven across the course, through more gates and into a marked circle where 15 plain sheep were removed from the group by Blake and Kevin, leaving five collared sheep to be penned.
At the mouth of the pen, the sheep lined up, ready to enter, but the bell sounded; the run was over, but with such a standard attained that it won the prestigious title.
Scottish judge Willie Todd of Langholm, Dumfries-shire, said: “Kevin is a master handler.
“Once he had the sheep, Blake worked very well on the course.
“This is probably the hardest international course there has ever been.”
Scotland won the team event, calculated on the scores of the top 12 dogs from each of the home nations in the two-day qualifying round.
Ireland’s 11-year-old Sam Fagan won the young handlers’ award.
