I know when we got Dudley he was 5m, I kept him in a crate when we're weren't home for well over a yr, not that he wasn't trained, but for the fact he felt is was his safe haven...
On weekends i started leaving him out (crate door open) when we ran errands, usually gone no more than a few hours at a time, i did use a baby gate to block off the hallway so he only had access to kitchen and living room, he did great, so I started leaving him out during the work days...
Now he has full run of the house and no matter when we walk in, he's always on one of his beds in our livingroom
