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.
Now I look again Portuguese Podengo could well be in there to a large extent. Lovely feisty little dogs. One smooth one I know quite well is very similar in size to a Basenji but shorter in the leg
Look at the BRAT mixes:

Check out Tia. I think that's what you are looking for. :)
Then look at Tyson and Shiloh. Not the right coloring, but similar build and coat….
