Yum had yellow pudding diarrhea a week and a half ago. She stopped eating for a day. Now she has a huge appetite, like 380 kcal per day. Her poos are mostly normal, maybe 1/3 are soft and yellowish. She was in Tuesday this week for BP (130, woohoo!) and kidney (BUN 63. Creatinine 1.8, Phosphorus 6.7) tests. Her vet suggests a course of metronidazole. Any comments on metronidazole?
