As you know I have two Rottie boys - they live in perfect harmony with each other 24/7. They never fall out over bones, toys, food - anything - I wouldnt have it!!! I feel safe to leave my boys together when I go out - they have the run of the downstairs - and when I go to bed they are left together. How many of you have to separate your pets for fear of fighting and how have you tried to over come this. I think every time you add a new pack member you are running the risk of them not getting on but personally I couldnt have a separated household where you are on pins all the time in case two dogs start fighting.
