Just looking at his size and stature, he is obviously far more confident than most Chihuahua's are and he has the front and back end (legs) that certainly look like those of a Basenji. Either way, he looks to be a very nice dog, bigger than his primary breed parent and certainly appearing to be slightly Basenji-ish. Handsome little brute he is! I'd get him I could, so you should!
Do you think there actually is any Basenji in this little dog?
