Take a look in the Breed Profiles here. From what you've prevously stated I would look into Much milder temperment dogs. Infact WHAT is it you expect out of your dog? Because the breed's you picked are WORKERS, What will YOU be able to give them exactly, other then an inexperienced home.. I'm sorry if I sound rude, but are you actually reading what your typing? Before getting Any dog, I would first buy yourself some books, dog behavior perhaps? Not Everything YOU read on the internet is True-FYI. But Seriously get into the breed profiles, you can read Alot of fabulous info-Right Here.
