I did vote "free run of the house" BUT....
I started off with crate-training. And every time I left him alone in the house, he was crated.
Once he did well with that, we moved to confining him to one room.
ONLY after a month or two of no accidents or chewed/destroyed room items (lol) then we started letting him have full run of the house.
Of course, we close the door to the room where the bird is, but that is only for the protection from the cat, haha! Sully is interested in the bird, but after getting his little black button nose pecked on day 1, he leaves the bird alone! LOL!!!!
So yes, now we do let Sully have full run of the house, but it's only because he's well trained.
