Don't be a "Bad Girl" or "Bad Boy" in a different tone of voice works in my household most of the time...lol. or they have nicknames and when they hear those they know they have done something wrong. For instance. Miss Itzi is idder bit. As mine seem to be very eager to please me...
I am very blessed. I think the best is the barking... Like when a dog barks on television they all go nuts... we just say "tv!!" and they stop. Or if they are barking at something outside... I will tell them thank you ,I see!! But you know that I have to be alerted to leaves falling..lol
