[Want a Doberman]

Hey, cool site. I'm not sure if this should go here, but In a few months I will be moving, and I'm very interested in getting a giant doberman at that time. My questions are, how long do Giant dobermans usually live? How much do they eat a week? What is a price range for a puppy with it's ears and tail already done? Anybody here breed them? What are some things I should know about them? I'm not looking to have a show dog, just a cool house dog and companion. I don't have any other pets, but there are some in the neighborhood, so it needs to be able to be around other dogs without a problem. I'm kind of one a budget and don't really want to spend a thousand dollars on a dog, but I love big dogs, and I love the look of a doberman. Thanks a bunch.
