I would definitely say that he has Basenji in him. We have a Basenji mix and without a doubt, he's the smartest, stubbornest and most loving dog we have ever had. He is three years old now, and when he was a puppy, my wife and I would joke about returning him for warranty work.
Your puppy is adorable and I'm sure you will love and enjoy him, as much as we do ours.
Re: Do your male basenjis squat to pee?
Our Basenji mix, Bailey, squat peed until he was almost 2 yrs old. Now he lifts his leg to mark and squats or stretches mostly to pee.
Recently, we were at a dog park and he lifted his leg to mark a fence. He has no pee left, so with his leg lifted he pooed instead. It was hilarious!
