Call names the owners pick, but as Lisa pointed out, very rarely before 8wks do I know what puppy will go to what home.
My kennel name is used at the beginning of the name or if co-breeding as I have done with lvoss we use both kennel names, example being Sophie is Kinetic-Tanza Soul Music. Most breeders either use a litter theme (I have not) but with my two new pups, Wanda did use a theme based on the fact that her and the sire owner had to have an "emergency" meet up for an additional breeding… Thus the names of the pups - AB Tanza Life In The Fast Lane, AB Day Trip To Tanza-Jamaa, AB Service While You Wait..... My other girl, no theme, I picked the name but still has both Kennel names, the breeders and mine. Klassic Tanza Color Me Tri
Note also that many times if a breeder buys a puppy from another breeder, both breeders kennel names will be incorporated into the puppy's name. So for my pups usually I give the new owners suggestions, but for the most part they can pick the name as long as I agree.... I refuse to have names like Poor Dumb Clyde (and yes that is a registered name of a Basenji)
