Last week I wrote about Bailey having loose stools. Well I took a stool sample to the vet and it came back negative. The vet gave me metronidazole. She started taking this last Tuesday and her stools were back to normal the next morning. Well this morning she had diarrhea again, a thick soupy consistency. I didn't worry at first, but after she ate tonight, the same thing. Like before, her behavior and appetite are still the same. I googled the medication and side effects. From what I am reading diarrhea is a less common side effect. Anyone have experience with this? I am going to call the vet in the morning, but wanted to know if anyone knew anything in the mean time.
