Some say that rules are meant to be broken and that times change significantly. When I got Laika, she slept outside in our car porch. Zoya wailed her heart out and found herself inside the house at night.
I refused to leave them inside unsupervised. Then a few children let other dogs out and they started staying inside all day..
Recently, it's been so cold that I've broken the no dogs on furniture rule and allow them to sit next to me when it's very cold. I still can't share my bed with them, but a bean bag right next to the bed seems like a good compromise now.
