My big dog used to sleep inside until I was pregnant and DP transitioned him to outside and built him a kennel. He'd still spend lots of time inside until we got the second dog, the little one, then they both went outside for most of the time (and shared the kennel, very cute!!). When big dog was a puppy we would leave paper out for him to pee on in case I missed his calls for needing to wee. I house trained him in about 3 weeks cos I was home all the time at the time and didn't have kids to distract me. It will pass. Housetraining a puppy takes less time than toilet training a toddler, so take heart!
Now that we're at MiL's we're keeping the little one inside at night and whenever she wants in the day, because she's got a high pitched bark and she's quiet if she's inside.
I had a pomx sheltie that I loved to sleep with when I was single. He would snuggle right up to me and if I moved he moved with me. DP couldn't stand it, and once, when the dog came with me to DP's house in the early days, DP put him into the back room. My beautifully house-trained dog very quickly taught DP what he thought of being separated at night... Poo everywhere!! That dog and I had a rapport that I don't think can ever be replicated. He was killed by a car only weeks before I found out I was pg.
