I just saw a post in another thread and it made me think of starting this one. Wemple posted that Winston said "Erf." I had to say it to agree that sounds like a yorkie soft bark.
Chloe, on the other hand, says "Beouf" for her soft bark. I guess she speaks French, and perhaps she's asking for something to eat, LOL!
When she's barking at the gardeners, she says, "raowwww."
What does your yorkie say?
(oh, and we all know everyone will be saying these words out loud to themselves as they're reading this thread! LOL)
