I know GSDs are vocal but Stella seems to have too much to say! She barks a lot when we are taking walks or when she sees another dog...(she is NOT aggressive, just wants to play), but it can be a bit scary for the other dog or person. Half the time I have no clue what she is barking at! I am guessing she is either excited or nervous....although she doesn't look nervous at all. Right now I am trying to just walk past whatever she is barking at and not make a big deal of it. I am wondering if this is something she will outgrow? She is 7 months old. Should I be doing something to correct her?
