Megan Young, from Milfield, will appear at the event, which takes place in the Fenton Centre, Wooler on Sunday, May 13, with her border collie Shadow and rescue dog Tyler, both of whom have competed at Crufts.
The 17-year-old began training dogs at a young age, and has been competing in dog agility with Shadow for four years.
During this time she became ill and had to undergo three emergency operations.
Despite this she has gone on to gain various achievements, including the Young Kennel Club Agility Dog of the Year title in 2012 and runner-up spot in 2012.
She also holds the Scottish Junior Agility Dog of the Year title, has helped break a Guinness World Record for the longest human dog tunnel and runs her own agility training classes.
Fred Welham, of the Yorkshire Working Trials Society and The Kennel Club, who built and pioneered the first agility course for dogs, based on a pony club-style event, said, “It is amazing that something that was supposed to be a one-off demonstration at Crufts has turned into such a huge worldwide event.
“I am so pleased and excited that we have upcoming stars like Megan to keep the agility event current and alive.”
Gates for the fair open at 10am. In addition to Megan’s demonstrations and have-a-go agility stall, there will be a craft fair, bouncy castles, pony rides, face-painting, mini-golf course, toughest man/woman competition and much more.
