He mostly basenji, but not full, he doesn't have the ears, t he tails a give away too, is it curly? 23 is kinda heavey for a Basenji full grown,
I wish 23 was heavy for a full grown Basenji, but it really is not. In fact it's in the middle with many weighing much more. I have seen some pretty large poorly bred, but also some big ones who were largely African years ago in NC at the nationals. I have seen a lot of basenjis whose tails were not right also, so that doesn't eliminate being basenji. But obviously no way to know for sure. I'd go with mix also, especially if those ears aren't fully erect soon.
In ears...they SHOULD be up... but that isn't always true even of registered basenjis:
One major break from the early development trend is African puppy ears. Both domestic & 3/8 litters had upright ears in approximately a week, while the Africans took much longer. In fact, 2 puppies went to their new homes at 15 weeks of age and their ears were not consistently up although they did finally come up; Roos between 17 & 18 weeks and Roosters by 4 months. <<
