Rowan is very submissive and I am trying to make her wait and come behind me. They said at obedience class that someday you might be carrying a baby or an armful of groceries out the door.. and you don't need a 75 pound dog barreling you over to get out first - so if I were you.. .I would follow Sam's recommendations - it only teaches your pupper manners... afterall, we are the leaders of the pack.
