Paige qualified for the award final by previously winning the YKC's Good Buddy of the Year, one of five categories which provide the line-up for the overall title.
She also regularly volunteers to help at YKC shows and at the two main events in the dog show calendar, Crufts and Discover Dogs.
Paige was presented with the Shaun McAlpine Memorial Trophy on the final day of Crufts in front of a packed audience at the YKC ring.
She also came fourth in the YKC Basic Obedience class and second in the Kennel Club Good Citizen Dog Scheme Pre-Beginner Obedience Stakes with two-year-old border collie Pebbles, and second in the Over 18 groom through class and sixth in the YKC 17-24 working and pastoral handling semi final with five-year-old bearded collie Puzzle.
The event is also for families with children thinking about buying a dog, as well as experienced young dog owners interested in finding out about the YKC.
Gerald King, chairman of the YKC, said: "Our Young Kennel Club activity weekends are very popular as they are a fantastic way for young people to develop and perfect their skills.
