You certainly are the expert. I have owned probably 50+ dogs in my life including several Labs, Lab Collie mix, Yorkies, Jack Russels, Shelties, Rhodesian Ridgeback, Scotties, birddogs, Bassets, Bloodhounds and others including mixed breeds of all kinds and unless I just don't recognize the sound I have never had a dog that made it. Cats, on the other hand do it all the time.
Now I live alone with one nasty tomcat. Although he 'talks' to me often, I've never heard a cat vocalize they way you describe. Maybe we live in two different, parallel universes.
