I can see why someone would think there was Terrier, but I'm not so sure about Basenji. (The only way to know for sure is to do a DNA test.) Both of your dogs look very similar. What breed, or mix, is the older one?
Wow! That is certainly a fascinating mix! ;-) Two sighthounds and a Spitz in there, so will probably see much the same sorts of behaviour as Bs….I bet she's quite a runner too! Good look with your girl!
The traits you described are also found in most of the Nordic/spitz type dogs. I don't see anything overly basenji-ish about him in the pics. What ever he is, he's very hansome.
