I never really crate trained. In fact, our "potty" is a 30x19 crate lined with a piddle pad. I just don't like seeing poo & pee exposed on a pad, so I have them go in a "room". I also have cute covers so they don't stick out & look so utilitarian. Plus, the sides are lined 1/4 of the way up so my boy can go crazy marking
When I potty trained, I kept them in those plastic travel kennels overnight only. I kept the new puppies tethered to me, so I could learn their potty signals. That REALLY helps. When it was potty time, I'd close them inside the wire potty crate. When they learned that's where they go, I removed the door so they could walk in & out when they need to.
If you're going to leave Miley alone for 8 hours, you really need to limit her free space. The bedroom might seems small to you, but it's a big new world for a little pup. I would def suggest an expen lined with piddle pads & just enough room for her to eat, sleep & play. You'll figure out her favorite spot to go & you can decrease the number of pads over time until you're left with one.
My problem now is that Prima is so tiny & she can't hold her bladder overnight. So she sleeps in her expen with a pad on the floor - no wire potty crate. I feel bad because all of the other pups sleep with me in the bed. But I can't wake up everyday at 2am to take her potty. And she hasn't learned to climb down the stairs from the bed yet. But that same set up might work for you.
I'll tell you what helped me soooo much...Prima's breeder gave me a used washable piddle pad that she used in her kennel. Prima had been using those before she came home. So she already associated the pad with the place to potty. Maybe you could ask your breeder what she used & you could get the exact same thing. Or maybe she can mail you a used washable pad. The key is...don't use enzymatic cleaners when you wash it. You want some of the scent to stay in the pad so she can smell where to go. Even with disposables...you can wet a small area with pee from a used pad onto a new pad before switching them out. I even left Prima's poo on her pad one whole day so she'd know she was supposed to poo there. Also, Nature's Miracle in the red bottle does work. You just have to clean the soiled spot it REALLY well. Wash it out with mild soap & water first. Then use the cleaner. I actually use a shop vac to clean accidents. I clean, clean, clean & suck up the excess with the shop vac. Then I spray the cleaner. You can also use a black light to see if you got it all up.
Anyway, although it's tough, confinement is really necessary when you potty train. Prima's only had one accident in 12 days. And that was when my husband was watching her.
It broke my heart to keep her separated from the pack. But it really does work.
Good luck!!!
