I have both sexes here since 2006 and have no problem keeping them apart or not mating, the girl wears hygiene panties when not crated and I am present. Less upset if both dogs can actually see each other,seperating in seperate rooms can cause howling and hunger strike from the males.
I packed Rhuari off to my Mum for the first season here, he was back in 3 days as he refused to eat [even his favourite scrambled eggs with strong cheddar] and whined constantly under his breath and lay by the front door, this when I bought my first crate and she was happy to be confined provided he was in the lounge and not confined out of sight.
I use vanilla extract on the bitches tail end and the males nose and chest to mask the scent, the lads would drive me nuts before someone suggested this as a way to keep everyone happy.
I live alone so no one around to accidently let the 2 get together.
