A purple comb is a sign of poor oxygen flow to her extremeties. I was thinking either heart problems or dry drowning. Dry drowning has many causes, but ultimately deprives the lungs of oxygen. It also has a delayed response that can take hours. You won't know for sure until a necropsy. When my Lucy died, we took her to the UC, Extension. They did it for free and had the results in less than a day.
