well it's been awhile since I've been in the ring, like years, but here goes
classes are age/gender separated, like 12-18, Novice, Bred By, Am bred, Open,
the winners of each class go into Best of Breed against each other (male & female)
They then pick a Best of Winners and a Best Opposite..I BOB gets the points.
You need so many points (15 I believe) to become a CHampion, that includes 2 majors,,majors are, you have to compete against a certain amount of dogs in that show..(majors can be tough, because there arent a ton of dogs competing)
Reserve is basically a 2nd to the Best of Breed winner,,should for any reason the BOB dog turns out to be a fake (not gonna happen),,the Reserve dog would get the points and BOB..
) Kinda like a beauty pagent if the winner can't fulfill her obligations the runner up gets it LOL..
Diane can probably better explain or fix my mistakes , she's more current than I am
