Ok. So. I looked up your thread on the other site.
You should have expected that they would tell you to shoot her, that was on a gun forum!
tell me. How much exercise and training does she get a day ? Does she go anywhere frequently (rides in the car, the park, etc) ?
Does she have a crate that she sleeps in ? & does she ever get any alone time with you?
Often in these cases.. There is LOTS of body language involved that you have looked over.. I'm sure right before the 'attacks' on the golden, she gets hard eye'd and stiff and stalks her.
Can you describe the attacks ? What does it sound / look like ?
