I like both. But, I would have to say female. All of my pets except Rufus are female, and they are the absolute most loving pets we've had. I've had a male before, but he had aggression problems (he was an ACD) My parents (mom and stepdad) were told he would get aggressive, and my stepdad got him anyways. He loved me to pieces though, but my heart and soul dog, Roxy of course, is female, so I definitely say Female!
