Cody is pretty vocal. He grumbles and grunts a lot, and screams and barks a little, but he's never yodeled or barooed for me… until today.
Every once in a while I'll play basenji yodeling videos on youtube, and he'll make noises in the back of his throat with his mouth closed. I was resigned to never hearing him sing :(. I guess I stumbled across the right video though, because he started making the closed-mouth-throat noises, and then after a bit of a struggle, he let out a few baroos and a short yodel! I gave him lots of praise and treats! Hopefully I will get to hear more of his beautiful voice in the future!
BTW, this is the video in case you are interested:
