We are thinking Spike might be a Basenji Terrier mix. He definitely has the basenji personality and the bark. We love him no matter what he is but we are curious.
We also have a possible Basenji/Terrier (Yorkie) mix. I've had some doubts, but seeing this picture of Rosie, I can't help but see my Rebel. Such a great looking dog, and if she's anything like our girl, you're in for a treat!
She is beautiful! All dogs are lovely but basenjis do tend to grab those heart strings. I hope you can find some answers, it’s so hard to miss them so much!
I don't see basenji in your rescue - she is a very cute doggie, and there very well may be feist in her. A DNA test would tell you everything and it's a good investment; it would help you know her personality traits and identify her behavior as well.
