Cujo is our 6 month old basenji mix! He's super playful, intelligent, and handsome! We've been trying to figure out what he is mixed with, any guesses would be appreciated! He is only 20 lbs and doesn't seem to be getting any bigger.
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?
I think I see some of the basenji ears, especially in the second picture. I just want to grab them and rub them good! :) It's most likely that there is at least a black lab there too. Also it may be not the first "mix". If it is a generation over there may be more then one mix in there. But either way, Lilly is adorable! :):) It's awesome that she has a good forever home now.
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.
