Have you had any success with finding out any rescue/adoption information? I am in a similar situation.
GA-Atlanta/Austell-11 Month Male Red & White Basenji-On Craigslist
This active boy wound up in a household that did not understand Bs. Mentions in the ad about keeping him as an outside dog: "He is at the age where he likes to chew so maybe getting some toys or keeping him as a outside dog would be the best answer or simply put up the thing you want to keep while going thru the teething stage." There is a rehoming fee. He is up-to-date on shots and is microchipped. He has an insurance policy at $25 per month that must be kept up. There is no mention of being neutered.
I have not contacted the owner to see if he is still available or who the breeder is.
Here is the ad:
