Always ask for references, history of of the clients, if possible contact previous people that the breeder has delt with in regards to people who have purchased from them.
Always go to the breeders house to see the parents, seek paperwork on the bitch (mother) sire (father).
Take stock of the conditions of the breeders kennels and living conditions, when it comes to buying puppies, reputable is the best way to go.
Details, details, details.
