Hi GoldenRetrLuver,
No we are not buying from a pet store. I heard that the puppies there are from puppy mills, although I don't fully understand what that means, I do feel more comfortable going through a reputable breeder. In fact I'm in contact with a very nice breeder at the moment.
I have researched the breed and my ex-room-mate got one a few months ago, so, I did see how they are young and I'm still learning.
They are everything I need in a dog. I want a dog that is affectionate, playful, and likes to be around their owners. I am aware that big dogs need excercise and I'm ready for that too.
