A. Diarrhea is never a normal symptom. She is rubbing her butt because of the irritation caused by the diarrhea. Withhold food for 12 hours, then put her on boiled chicken (no bones) and rice for a couple days (every 6 hours- small quantities). Go back gradually to her food after that if it helps. If it gets worst on not resolving get her to a vet, she might need antibiotic treatment.
