While browsing here and doing research on the breed I've found a lot of information about same sex aggression in Doberman, mostly male/male aggression. We have a male chihuahua and most of the dogs in our extended family are male with a couple of exceptions. We've already decided on a female Doberman for our next dog, but I have a few questions. Are females typically less dog aggressive in general? Is female/female aggression as common as male?
