No, there are usually 2 from each breed awarded a CC - the Best Dog and the Best Bitch. These two then compete against each other for Best of Breed (for which there
isn't another CC).
The dog classes are judged first, in order, and 1st, 2nd, 3rd etc awarded. All the class winners (1st place) then come back into the ring to compete for Best Dog (CC), but
only if they haven't been beaten in a subsequent class.
Then the process is repeated with the bitches.
And yes, 'unbeaten' only refers to the placings at that particular show.
Hope this helps.
