Yes and no. Individually I think they're all easy. As a group (mostly the girls), no they're not easy at all. I am almost positive that 90% of the issues we have with the girls would be resolved if I were out of the picture though. I'm just not willing to test that theory with the health of my dogs (and/or other people). And I can't really remove myself from the picture so any test would be for my own curiosity lol.
On the plus side, they can easily be boarded separately, house-sat, or go to other people's houses. I'm just incredibly picky about who/where/when/what in those situations, especially when it's at my house with all three of them. And especially with Mu because if she gets a chance she'll go looking for me.
