The floor is dirt - I occasionally sprinkle baking soda and rake it through. I will say that my B does most of her bussiness on her walks but she is able to go out the doggie dog and use the "poop station" at any time. This station has been a godsend for me.
Most puppies or young dogs will chew up things. I think Basenjis are worse than average, but I'm not they're are that much worse than average. They may just be more inventive.
It's also an age thing. At some point, I'll say 2 years old, they grew up and you don't need to crate them.
I wouldn't think of not crating a pup or younger dog. Too many things for them to destroy. I also don't think they mind the crate. Sleeping in the crate on on the sofa, it's more o less the same.
As far as getting a companion, I think that's a good recipe for partners in crime! LOL
As a kid, my parents basenjis ate the kitchen cabinets and half a kitchen door.
Alone for 2hrs.
That's what I have ! half doors between the kitchen and the rest of the house. The Basenjis stay in the kitchen with access to a large garden, until evening when they are invited to sit on laps in the lounge.
Only trouble with that was that Deedles, when 8 months old, realised a bitch we had just rescued the day before was in season. Her previous owner hadn't told us. The Dastardly Deed was over the half door and into the bitch before you say 'knife'. (An English expression !).
He obviously knew what he was doing because we kept the resulting singleton bitch and she was Top Brood Bitch in Breed 3 years later !
