@adina Thanks so much for this. The breeders we are looking at seem to have all those boxes checked and we found them through AKC. We are hoping this is surely a trusted source...
Alas, AKC lists breeders who have paid to be listed. There is NO vetting. Please apply due diligence in choosing your breeder.
You should spend almost as much time researching the breeder (and the sire and dam) as you have the breed of dog. The breeder can let you know much of the pup's temperament and potential character.
