Many, many years ago, early 80s, we were walking our several basenjis along the street near our home. A car stopped and a man in his 30's got out and was amazed to see so many (5) basenjis. He had spent the last 10 years living in Africa, can't remember where, and said that where he was, small packs of basenjis roamed, wild, but would occasionally just "move in" to a village. Some dogs would stay with the humans but after some time, most of the pack would move on. I imagine the "moving-in" was for scavenging, and some may have decided they liked scraps!
This is purely third-hand, told to me quite unsolicited, well over 25 years ago, Snorky 998's post triggered the memory!
