My 4 year old BLF will whine a bit, but only when she's bored and the coots are around. You see when she was a pup and the ducks were few between I would shoot her coots, the coots gave us something to do and built her enthusiasm for the game. I only shot the coots for the first year, but now at the break of dawn when the coots get out of the tules and make their way into the pond my girl just can't figure out why I'm not shooting them for her. I don't have to get physical with her to stop, a simple "quite" usually works for a while.
Other than what was outlined above my dog is not a vocal dog, she does not whine during training or testing. And when the action is good in the blind, not sound. My son says she has ADHD, I can't argue with that.
