Hey that is a really good question! i had to look up the answer because I wasn't 100% sure but this is what the akc says
Words and phrases that may not be included in a dog's name:
Champion, champ, sieger or any other AKC title or show term, either spelled out or abbreviated.
Obscenities and words derogatory to any race, creed or nationality or transliterations of such words.
Kennel(s), male, stud, sire, bitch, dam and female.
Breed names alone.
There are no restrictions on arabic (1, 2, 3), cardinal (one, two, three) and ordinal (first, second, third) numbers that are spelled out.
The champions on Ritzys site are champions of record though, i know that for a fact. I like that the pedigrees are listed on her site - I have more than one relative here!
