I have 2 rotties that are and one that is not. My griff only speaks when he wants something really bad....lol. Dutch, my oldest, sounds like Chewy from Star Wars when he gets going, it's the funniest thing. I was just curious how many other dogs "talk" to their humans. My Annabelle, the youngest rottie, is very vocal, if she wants my attention she makes the weirdest noise. Which I have most likely "trained" her to use that sound to get my attention because it's so darn cute how can ya not.....lol. She is a smart cookie.
