I see no one is really interested in touching this issue because it tends to get complicated once it becomes a problem. Again though, it really comes back to operant conditioning, everything does in the end.
I have a pretty noisy pup so here are some of the steps I've taken along the way to try and make sure I don't have a problem later. These are just stupid common sense things that I think apply to pretty much any dog.
1. She was very noisy in the crate initially. I was very careful never, to ever let her out while she was making noise. I would literally put her int he crate and leave the house, sit outside and read a book until she went quiet, then go let her out. If she got noisy when she saw me I walked away and came back again after she got quiet. Message... Be quiet and I will come let you out.
2. Early on I taught her to sit and focus on her food bowl for a period before being released to eat. Initially this included some whining. I always, every single time waited until she was quiet for at last 3 seconds before releasing her. I extended this over time.
3. She learned in collar conditioning to anticipate the pressure and became vocal. The very first time I heard this I addressed it by mixing up my routine and giving more freebies. She has done it a couple of times in FF and beginning pile work and every time, I simplified, varied my routine and laid off the pressure.
More or less every time I see have seen the behavior since she was 7 weeks old I have employed extinction as a strategy to reduce the noisy behavior and positive re-enforcement to encourage quiet behavior. I've had to employ the strategy multiple times in multiple situations but it has worked each and every time with a bit of patience and thought.
Will it work as excitement levels rise in training? I don't really know but I have tried all along the way to address what I recognized as a potential issue from the moment I got this puppy. She seems incredibly talented otherwise so I would never have walked away from her.
