Also if you contact the breeders in the PNW listed on the BCOA site that LVOSS posted some may have puppies/juveniles/adults available. You can also find contact info for basenji fanciers on the Willamette Valley Basenji Club site http://www.basenji-club.com and Evergreen Basenji Club site http://www.evergreenbasenjiclub.org/
Send the folks an email or give them a call to check availability! I wish you luck on your journey to find another basenji companion
