A female accordingly to one researcher is a bit different from the male. The pros/cons are unclear or at most 50/50 for the females, the males are a much different and clearer story.

If you are truly a responsible pet owner, don't let your male dogs roam, keep them on leash when outside,etc then you won't be contributing to the pet over population problem. For males marking is a behaviour, that yes can be trained out of most dogs. My male BRT does not mark in the house, nor does my male Yorkie. It took a lot more training for my male Yorkie than for my BRT. Neither fully intact male is dog aggressive, or for that matter people aggressive.

How did you train him not to mark?
