At that age, I'd say she's learning these commands and not really 'knowing' them 100%. So some of the vocalizations you're referring to sound like she's still trying to engage in play. Grim has 'chewed me out' a few times for things... he's also very vocal. Maybe teaching 'speak' so you can teach 'quiet' would help. We're working on 'hush' right now. It has helped to some degree... but when you have a vocal pup it's a double edged sword because not only are you trying to teach them to stop vocalizing when you want quiet, but you have a pup who is full of energy, etc. and may not fully understand the commands given in the first place.
