I have a mini Dachshund and she sleeps in a crate at the end of our bed, its got lovely fluffy blankets and bed inside and got a blanket covering the roof and sides so she just loves to burrow into it at night with a couple of treats. I dont ever close her into it either she goes in at her own choice and can come out when she wants. When we initially had her she slept in our kitchen but she hates her own company and used to howl every night so she is loving life being able to be in our bedroom but have her own space too. I would be too afraid of her with us during the night as if we rolled on her she would suffocate. But during the day she takes herself upstairs and will either go into her crate or lie at the bottom of our bed and stare out the window. In the evenings she sits on top of me on the sofa, being beside me isnt enough

She doesnt moult but even if she did I wouldn't care - I was raised with long hair German Sherpherds and they moulted a lot so I am well used to that situation.
My dog is my baby though, I absolutely adore her, potientially more than my partner at times!
