@gregg-biggs - You might check with rescue in So. California, www.basenjirescue.com if you have not. You might also try breeders in the Pacific Northwest to see if they have an adult they might want to place. You should try Kathy Britton, she is in Portland area. You can find her contact information at www.basenji.org that you can search by state.
Medfly is slowing down now. I speak with Karen and Chuck fairly frequently. They’ve become like extended family to us. Basenjis in need of rescue near them have become extremely rare.
It’s a drive, but also keep your eye on Colorado Basenji Rescue.
EDIT: I just spoke with Karen at Medfy aka BasenjiRescue.com and they have retired from rescue. They're getting older, they're faced with issues of getting older, and the work has become too much. She's asked me to pass that on to all of you here.
Colorado Basenji Rescue has a black & white male almost ready for adoption. His name is Ranger but, from the description, he appears to need to be an only child. http://www.coloradobasenjirescue.org/adoptable.shtml
