Thanks again everyone. I just read my vets e-mail response and she wants me to fast Pearl for 24 hours and to also try to bring in another stool sample. She also wants to see Pearl tomorrow. Since I did have a 9am appointment I think that's when I'll be seeing her. I'll continue to keep you updated. I think that she may need a longer course on antibiotics or a different kind this time. She seemed to be doing much better while on them the last time.
