@ Robert J, and others faced with these issues.
You could try one of those dome in the middle dishes that are designed to slow down her eating…….wet her kibble with water prior to serving.
But, honestly, something is wrong, and I would ask your veterinarian what further diagnostic tests are needed or to refer you to a specialist.
The sooner you get a correct diagnosis the better, and you can begin treatment. Read the previous posts in this thread, there may be more to it than gastrointestinal upset.
Her behavior is not normal and obviously the dog is in distress.
I would refrain from trying over the counter meds and such or making drastic changes to her diet, unless instructed to do so by a veterinarian that has examined your dog.
