I can understand where you're coming from, Anthony...
This is my take on it. I have a GSD that is likely very weak-nerved though has barely shown it... He used to growl at people if they grabbed him for pets and he didn't know them, on leash.
That's not going to stop me from taking him places, doing things with him (agility, dock diving, flyball, dog park) and having people over. Some people think I'm setting him up to fail, some people think he's amazing and incredible, some people don't know him and have no opinions. I
know exactly what his threshold is that MIGHT illicit a growl, or has in the past, even though with the help of a trainer we have worked through this intensely. I don't let anyone pet him when he's leashed, and when we're at the dog park in the office, he stays by me, if anyone gets too interested in him I tell them he's pretty aloof with people and would prefer you to just throw a ball for "bonding" time instead of hug him like a bear... If I can't supervise, he's crated.
It took us a good 6 months to a year to figure out WHY exactly he was doing this, then to fix it (it was related to a medical issue, but being weak-nerved, it just kind of stuck around a bit, after) and carry on our lives. In that time we tried a lot of stuff, I had a lot of "helpers" test him and a lot of training happened. He was put in numerous different situations under my watchful eye (just like your situation!) to see where he would start getting stressed/agitated.
Now we're to the point where I know his threshold and keep him under it, I'm never going to push that for any reason, and I do all I can to ensure he stays under it, even if it means yelling at people or shoving them (which I have and will do to ensure my dog is safe and alive, even if it means getting an assault charge; I'm not going to lock my dog up in my house for the rest of his life... he's only 3) to avoid conflict/contact.
We can have people over just fine, anyone can walk into the house, he's not going to fret or get stressed like Kira might. I don't know how long you've had these issues with her or the full extent of them... but it seems like you're finally getting to the point where all-around in any circumstance you know exactly what she can and can't handle, as noted by the change in behavior. So now you need to start making sure you keep her below that threshold... if she started to act stressed after so many people or so long, or maybe when she finished her bone, don't wait as long next time. It's not to say that your dog can't be a dog and a part of the family and fun, just cut it short to avoid her feeling overwhelmed next time. Or, just let her meet everyone for a moment then put her back away, for an hour or so, then let her out again, so that she's still getting attention and potty breaks and you're not feeling like you are abandoning her, but she's still under threshold and safe.
I hope this makes sense, and good luck with her! I'm certainly used to being treated like an idiot about my dog from people online... whom have never even met him, most of whom who haven't even SEEN him. So don't feel too bad about what people say on the internet.
