Poor girl. There can be many reasons for her diarrhea, including: intestinal parasites (i.e. Hookworms, roundworms, etc), dietary indiscretion (eating something that didn't agree with her stomach), foreign body ingestion or an underlying conditon (i.e. Stress colitis). If the probiotics don't improve her conditon within 48-72 hrs or if she develops other symptoms, then it's best to have her seen by your vet for a thorough examination and potentially diagnostic tests (i.e. Fecal exam, bloodwork, etc) to find out the cause. In situations where stress can be a cause of the loose stool, a short course of antibiotics, probiotics and a bland diet are successful in normalizing the stool. You can try a bland diet (i.e. Tuna and white rice) in addition to the probiotics that you have already started, to see if that makes a difference. If not then a vet visit is highly recommended. Best wishes with pet Zeus. Take care.
