That's the perfect word for it! ~"Yodel"~
I was trying to explain to my hubby the noise that Coby makes when he hears the garage door open. I thought it sounded a bit like someone was removing his toenails .... one at a time. But now... I think I'd consider it yodeling! It is the most ridiculous sound.
He does it to a lesser extend after he's barking at someone/thing outside and is told to hush up. My daughter said the neighbors probably think we beat him when he barks. Because from outside, you'd see a head looking out the window, then a ferocious bark, then a stupid-sounding warbling noise that probably sounds like he's being strangled.
We should probably do videos with sound........
