I think it depends on the personality of the said Basenji.
I have read plenty of stories about how destructive Basenjis can be. My little guy has actually been quite an angel. Some furniture chewing, but I have since corrected it. Naturally (when he is not anxious) he has absolutely no motivation to destroy anything. Not all Basenjis are like this though. I remember the breeder told me he simply wasn't the destructive type, and that was indeed true. Others can easily be destructive though.
I have read about Basenjis tearing apart couches and chewing on drywall, etc. It all depends on the environment, the personality of the dog, and the general obedience. Some owners have to crate their dogs during the day, others (like myself) leave our basenjis in our homes during the day where they can roam around without any destruction. It can simply vary.
To give you an idea of what can work, I am gone from about 8am-4pm during the week. Kananga gets a 15 min walk in the morning and a longer walk in the evenings. Usually 4-8 miles worth of walking on the weekends if the weather permits. He does fine during the week. I think he sleeps all day while i'm gone. His weight is good, he's happy, and he sleeps well every night.
In all honesty, out of the handful of dogs I have lived with at one time or another, he's been the easiest. But, again, it can vary.
