Good luck. I think the Off switch comes highly recommended.

Here's a video of Juliet getting frustrated and grumbling when I withhold rewards. I was shaping her to move around the book with her hind legs: http://youtu.be/G4FGmBRROQ4

My favorite is when she does it for Sit/Stay. She thinks Stay deserves lots and lots of treats. If she's not getting them she does Down to see if that's what I wanted.
I could be wrong but I think your problem is Juliet is working on a fixed reward ratio. 1 behavior 1 reward. When dogs expect that they give up quickly and get frustrated when they don't get the reward. Think vending machine. you put your money in ,you expect something back. If you don't get it you wanted to beat the machine.
You need to teach her that you a a slot machine. That sometimes she will get a reward for 1 behavior something after 3 then 2 then 5. She will keep trying and never know what will get the response. To start this, start being selective over the quality of the behavior. For example, you want a sit , click or reward the fastest or straightest one not just a sit. Once the behavior are learned in the earliest form you need to start asking for more.
Also don't let her give up. Wait her out,if she tries to leave put a lead on her and just stand there until she does something you can reward. She needs to learn that she just can't pick up her blocks and go home but she needs to work. I have waited on Diva for over 30 minutes to get a certain behavior and Ember over 45 mins(not kidding-it was teach her to take the dumbbell). Once they learn you won't let them quit they figure out another solution. I just happen to be more stubborn then a female sheltie which is just slightly less stubborn than a mule.![]()

Seriously though both mine grew out of the grumbling and the muttering (well mostly) as they got older and Tully is much better at containing her energy when training.I could be wrong but I think your problem is Juliet is working on a fixed reward ratio. 1 behavior 1 reward.

Oh dear, I hope it's not yet another prolonged adolescence!! 
Aha, I just put the volume on. That growly bark is adorable! Buffy does the little yippy growl/bark if she thinks she deserves more treats too.![]()
