Hi Gretchen. CBR in Colorado does have a pair of R&W seven year-old siblings: Cairo and Cleo. However, they would have to be adopted together. Here is their website: http://www.coloradobasenjirescue.org/adoptable.shtml. However, CBR is not moving doggies right now due to the COVID -19 issue. I am looking for a male puppy or very young male right now. Just not happening. Looks like patience is key right now :0)
Hopefully brat or camp basenji contacted the owner. More hopefully, the owner contacted the breeder who generally has first right of refusal to take back their puppies.
I am one of BRAT's Basenji mix coordinators. Most of the Basenji mixes I come across are probably not that Basenji, but some of them definitely are. Of course most are not from known parentage. This dog is currently on the BRAT adoption site, I'd say that she's a fairly high mix: http://www.basenjirescue.org/DOGS-MIXES/MS/MS-Bebe.asp
