My boyfriend and I got our Basenji in February, and he's 9 months now. We did our research, used positive reinforcement training, crated him at night until he was potty trained and then let him sleep in the bed with us, and we had extensive play sessions with him in the mornings and walked him until he (or we!) got tired in the afternoon/evening. He's crated for a few hours during the day when both of us are at work; we live in a small apartment with no room for an x-pen, and are considering doing some test runs with leaving him free in the apartment, because he hasn't been destructive the few times that he has escaped his crate.
Result: he sticks to us like glue. Though we rarely get to let him off-leash anywhere, he likes to keep us in sight and keeps a watchful eye on strangers who come near us both in and out of the house. We still have playtime with him in the morning (anywhere between 30 mins and 1 and a half hours of fetch, tug-o-war, chasing, and the Basenji500), and we try our hardest to give him a good long walk before we go to bed. He's okay with the crate, though he doesn't hang out in it of his own free will, but he tolerates it for when we're gone.
His most destructive times are in the morning when he wakes up before us and decides to see if we were silly enough to leave any clothing or paper in his reach to shred up (we've lost money, a deck of cards, shoes, underwear, shirts, bookbags, etc.), and in the afternoon when one or both of us happens to be home but not paying attention to him, so he starts tugging on drapes, bedding, even the carpet - but more to get our attention than actually ruin anything.
It's work, but Paco makes it worth it in the end with cuddles, doggy-smiles, and never-ending enthusiasm!
