We have a poodle. We set up a small toddler pen (google iris pen) next to our bed. Put in a dog bed and a blanket next to it. He sometimes slept in the bed, sometimes on the blanket. Sometimes on the floor if hot.
He whined to go out once a night for the first week, with each night going longer until whining. He is now 12 weeks and has slept through since 9 weeks. Every now and then he wakes before 6 and I shhh him - "settle down" - and he goes back to sleep.
Definitely carry straight outside! Peeing on the mat happened once, never again! Kind of a PITA in the cold weather, a lot of fumbling around getting coat on with one arm at a time.
Have fun, totally have loved getting a puppy! He is so amazing. And a ton easier than a baby, after being terrified of coworkers telling me it was like another child. Nope. Maybe they had super easy babies.
