Ruby always yodels when I get home from work. In fact, the whole family tries to be the one that gets a song whenever they come thru the door. My father and I are usually the ones who get it…but once she did 4 long yodels for my brother. I wasn't a witness so I joke that he made it up that he got that much from her.
Also, ever since I changed Ruby's food to Evo, I say, "tell me" right before I put her dinner in her crate, and she yodels and then runs to the crate.
Anytime she yodels, she gets lots of praise and usually gets a treat of some sort as well.
Ruby is definitely vocal...and I LOVE IT!!!
