Yeah you can't show spayed females and my mum wants to breed from our older girl sometime. Although I am personally against the idea because I think there are plenty of nice German Shepherds out there without us adding to their numbers.
They get rotated through the house. So one will be inside in the kitchen with the baby gate across the door and then one is outside in the yard. Then our desexed male goes in or out with whoever.
I honestly just want to move to a country property where we can build them large grassy runs and have them outside most of the time. Suburbia sucks.
