Here is Kwame howling along to a soap that we get in the UK. Cali doesn't howl or yodel but she gives you lots of sqeeks when you come home!

Duke makes sounds very similar to Kwame in this video - ONLY - when I "cock-a-doodle-doo" like a rooster. The longer and louder the "doodle-doo", the more sounds Duke makes. I feel like/look like an idiot doing it, so no video. :o Daisy doesn't do or mumble anything when we "sing" - just watches. 
EL D doesn't vocalize much at all but my previous beastie used to do that raw-throat thing when he was left in the kennel at my brother's or some other place that he didn't want to be.
My Cody is virtually silent. I have to mimic a basenji howl and hit just the right pitch for him to howl and yodel. And the pitch is different on different days. So I look/sound like a crazy person trying to get Cody to make a noise. Aurora has never howled or yodel. But her back of throat growl grumble sounds like something you hear in a horror movie and she's the evil monster.
Trixie finally decided at 6:00am this morning to become vocal. She has done the barooo sound for a while but this morning my alarm was going off. I don't know if she did'nt like the sound or what but she suddenly gave 4 very long and very loud!!!! siren sounding yodels. It was great!!!! She also does that low I call it devil talk when she does'nt agree with something. Kind of scary!
If you read some of the comments on the video's one person commented "This is the reason I would never get a Basenji."
It's not even close to reason not to, but something all basenji owners cherish, as 99% of time they are silent.
I like the "dirty looks" my dog sometimes give other non stop barking dogs, like they are saying "Shut up!" or what's wrong with you.
Lenny's breeder can make one of her dogs howl on command and then they all join in… Mojo (the ring leader) is off to the left of the screen...

Layla talks constantly, talks back too when she's in trouble she howls all the time. Caira growls a lot becuase shes a cuddle hop and queen of our house. and Ramsey talks a little and every once in awhile hell belt out a howl but he is loud and sound beautiful.
My dad can get Senji to start howling, if he mimics a howl. Sometimes, my brother will join in too. It's hilarious to see 3 "men" howling together. My mom gets mad because she thinks all that howling is hurting Senji's vocal chords. I also noticed that Senji is more vocal when there is a full moon.
I can only get my kids to "talk" on command. I try howling and yodeling to get them to start and they just look at me like I'm an idiot. My husband does too. lol…

Cute, cute, cute video!!!

Nexa and Leo thank you for this tip, they thought I was crazy last night when I started "cock-a-doodle-dooing". Leo cocked his head sideways, probably thinking his owner has gone off the deep end:D Not a peep from either of them.
I played Lenny's YouTube yodeling to EL D today – boy did he go nuts. First he twisted his head so many ways to try and figure out where the calls were coming from then he sat and cried (never did howl along)
It seems to depend on the dog. Male Louie has yodelled once in his life (2 years old). But little female Shelby is very vocal. She always gives us one big baroo when we first come home from work.
