Hmmm, no breeders names are supposed to be used, although I think people who name their dogs and the dog's name includes the kennel name, well, that kind of lets the cat out of the bag. But as far as saying anything good, bad, or indifferent about a specific breeder, I think that's not supposed to happen. If you have questions about your breeder, you could invite private messages from board members, or send a private message to a member who you think might know the breeder and communicate through those channels, not on the open forum.
My dogs may have siblings or half-siblings on the board but I don't know. I haven't asked and I haven't said who my dogs' parents are. I wouldn't know that via the board, only if I found out some other way, even though it would be cool to know.
