Ok so I'm new here an I got a couple questions. First of all my GSD is a 16 week old female. She's not very vocal towards me which I find kinda odd and making training her to speak somewhat difficult. She barks at other dogs but not very much at that. The most vocal she gets towards me is whines when she needs out and she'll whine at me but that's about it. What a y'alls thoughts on that? Second question, she's got a pretty serious personality to her and she's never been overly playful. She's not shy or timid and she's really smart but just not very playful and never has been. What's up with that?
