When dogs have gastrointestinal upset it is best to feed a bland diet--boiled chicken or hamburger and boiled rice. I would stop the scrambled egg. Also canned pumpkin is good to feed as it is high in fiber and can help firm the stool. Plain yogurt can also settle the stomach--it has a good probiotic. If the diarrhea continues for more than 48 hours or your dog shows other signs of being ill seek veterinary medical attention.
Don't know about the scrambled egg, but the boiled plain rice should be okay. Most importantly, you should have your dog examined by a vet so you can find out why she has diarrhea.
