@mr_smokeyd I don't know about Atlanta specifically, but I would recommend contacting BRAT. They don't restrict their rescue to one geographical area.... I'm sure they would be able to connect you with a district supervisor near you.
Please go to Basenjirescue.org and join as a member. It will show you are serious about helping. BRAT always needs good foster homes. A home visit will be required (not sure if that is possible at this time considering this COVID-19 crisis). It is especially helpful if you have basenji experience. Not always, but very often, a basenji coming into rescue has special needs (i.e., behavioral, medical, etc.). It is good to ask yourself if you and your family are willing to deal with that. Fostering is hard but it can also be a wonderful and rewarding thing to do.
