My 6 month old Zoi had bloody muccusy diarrhea last Sunday I took her to the vet on Monday and he put her on three doses of Sucralfate 100 mg and she was better for a day the the diarrhea came back no muccus this time. She is eatting good and acts like she feels good. He checked for worms on Monday and on Friday and now she is on immodium and still has it. She has been on the same food for two months and I have cut out all treats. What the heck. What should I do now. Take her back to the vet, get another vet or what?????
