No breed of dog is innately obedient. You'll have to teach them what you want them to learn. Just like children. Adding a dog to the family is a big responsibility. Finding a reputable and ethical breeder can be difficult.
Any person can put a male and a female dog together and call themselves a breeder.
A good breeder will interview you. Just because you have the money doesn't mean that you should have one of their puppies. A good breeder guarantees the structural and genetic health of the puppy. A good breeder is there for you throughout the life of the dog to answer every and all questions that you have. A good breeder has a contract that spells out what the breeder expects the buyer to provide for the life of the dog, shots, shelter, food, etc.
