You actually want her to be vocal?! I think a lot of people would love it if their dogs would stop barking all the time. They actually make anti barking e collars. So, as of right now, I would be thankful. As far as play is concerned...what kind of playing are you trying with her? I mean, if you have a rope, don't just give her the rope. Make it active...twirl it or something. If you give her a stuffed toy, move it around. If you give her a ball, tease her with it. Throw it from hand to hand in front of her, or do something. My pup didn't know what to do with all the toys I gave him until I made them "active."
