@dillinger So he's still a really cool looking dog! I like that you can hold him, his expressions and that he seems ok with kids. And I like that you are a Dogophile.
That he's not a Basenji is no reason for you to leave. PLEASE STAY! We can get you to a Basenji. Also appreciate your honesty about a few issues with him. All seem Basenjiesque. In my opinion... a Basenji... especially a puppy "might" exacerbate the problem. Don't give up yet! I haven't. More folks will jump in here soon...
The good news is you have some behavior issues which, if you can overcome, they'll give you invaluable insight into how to interact with a Basenji. My concern is that if you haven't gotten there yet... ya might be doubling down on a losing hand. Honestly... it's about you right now. Your commitment, training skills and consistency. Your ability to affect changes in behavior with training. If you can do this with Dill... I'd bet you can do it with a Basenji. He needs more work. I hesitate to give too much advice cause...there're more qualified trainers here than I. I know basics.
At the very least you'd need to meet with a breeder, with Dill, and see how things went with the pack or the dog they might be thinking of.
Work with Dill more. Ask more questions. Describe behavioral issues in more detail. Let's work on that first.
My wife didn't want a second dog/Basenji either. We ended up with two and then six puppies, with my Breeder's prior approval and guidance, for a short time! I had EIGHT FRIGGIN' Basenjis at my house! Ain't no one takin' that from me! I had eight Basenjis.
