Logan has a reversed question mark tail when she's on the prowl. She doesn't bark like a hound but I did give that a thought, thanks. She does have some purple spots on her tongue (Chow) It's not a big deal, I was just curious cause I wanted to understnad her better. I adore her, regardless. I'm so glad I rescued her -she's so "at home" already! She's quite a character! Her first 2 weeks of impeccable behavior is ..well...OVER!
