Hi All, I am not yet an owner, since I am still in the research mode. I am trying to gain as much knowledge possible before making a commitment to one of these beautiful creatures. I have been doing a lot of homework but would now like a little advice please, two items: 1. As a first time owner, is there any advantage to owning one variety over another (health, size , aggression, ect.)? 2. Does anybody know of a reputable breeder in the Chicagoland area? I'm from McHenry, Illinois, located far northwest suburbs of the city. Thanks again, this looks like a great site.
