My dog (2yrs) had diarrhea and was vomiting. I took him to his vet and the dog injected 2 meds and prescribed Metronidazole 250mg to be taken daily w/food (full stomach). The vet said to give him babyfood till he's better. Once my dog started eating the babyfood, I gave him his 1st pill. However, I haven't given him the 2nd dosage because my dog won't eat or drink water. He has a lil diarrhea and is going frequently although it's not much what he excretes. My question: can & should I cont to give Metronidazole on an empty stomache? He's lost his appetite and I worry of giving the med cause of this.
