Selecting a breeder is a personal choice. The criteria you use is what is important to you .. location? .. hours of service? .. friendliness? .. commitment? Your goal should be to find a professional that meets your needs.
Breeders typically maintain a history of your future pet, including health records. A good breeder will also question you regarding your ability to properly care for your pet. Common sense, open honest communication, a little research and a few questions may save you future grief.
