Neil: Flagyl would be the only other drug to add, but the other two drugs are quite appropriate for this condition. If he was just started on the drugs, they will take a week to 10 days to start working. If he is having trouble eating, then he should have soft food (e.g., chicken baby food, without vegetables or sugar), as others on this message can certainly recommend. As always, let your veterinarian know. Do not wait. Kind regards, Freddie Ann Freddie Ann Hoffman, MD [Posted in FML 7442]
