Fable has had diarrhea going on 3 days now. There's nothing unusual about it, besides that it's not a healthy firm stool (meaning no blood, odd colors or anything). I looked in my kitchen for the most bland food I could find and found plain white rice. As her diarrhea has continued, she's been getting more rice and less kibble. Still, it's not better. She isn't showing any other unusual symptoms. She's energetic, playful, has a nice big appetite and drinks plenty. She was filthy, skinny, and wormy when I brought her home, but she'd been dewormed and is extremely healthy besides this one thing. Any advice? She was just at the vet for vaccinations where she passed an overall health exam with flying colors. The vet said she has "gold stars all over." She didn't have the diarrhea then, though. Should I take her back to the vet?
