How to clean Kool Aid and other tough spills?

Last night I spilled a cup of red fruit punch, immediately blotted the spill, I could not wet vac the carpet at the time because there are two babies in my household and our wet vac is VERY loud. I did however vacuum the area this morning and went over the spot with a mixture of; Simple Green, Carpet Cleaner and water. My carpet is a basic cream/oatmeal color so the stain looks horrible, it did lighten after the first and second scrubbing today, and even though I scrubbed twice and the color got a teeny bit lighter, It is still very prominent, and a major eye sore. Not sure what else to do, has anyone else found a solution for red/colored spills? And what is the best way to clean up a dog accident and keep them from doing it again (I have puppy mill rescue who gets very nervous, and yes I know that there are "pet diapers" for pets, but that is not an option. All help is appreciated!!!!
