Hi Zoeys Mom & Zoey!
My Gracie Ruth (15 months old) is the "alerter" of our gang. She will let you know if she's heard a 'dangerous' sound, even if it's 5 street away.
She'll also tattle on the other 2, if they are doing something
she thinks is wrong. She sasses back when scolded and is basically very vocal with all types of noises about nearly everything. She's my talker, that's for sure. I find that a touch on her body or a gentle tug on her beard along with a Quit command has worked to get her refocused. Mostly now, just the command will get her to stop barking. Then she will come to me grumbling and yammering the whole way. You can just hear her saying, "But Momma! Didn't you hear that? I heard it. There's danger and I was just helping you keep us all safe."
Just keep after her, be consistent in your correction and she'll probably get better. But I think it's just in some of them more to be vocal then others.
