Battle Ground — Battle Ground High School student Raina Moss and her clumber spaniel, Betty, have been invited to compete in the largest prize-money dog show in the world, the American Kennel Club Eukanuba National Championship. Moss and Betty will compete Dec. 17-18 in the National Juniors Obedience Competition, the Limited Junior Showmanship Competition and the Best of Breed competition. Moss has been showing dogs through Clark County 4-H since she was 10 years old. She is still active in 4-H and volunteers with younger 4-H members, helping with guidance and agility instruction. This is her first year qualifying for the invitation-only dog show. Moss and Betty competed in shows throughout the Northwest during the past year to qualify for the event. Moss will compete with more than 150 youth from across the country for educational scholarships and awards. The national championship will be televised Feb. 4.
