Thank you all for your concern. Belle is fine(she has a cast iron stomach) - the vet said the OD could cause exciteability. I noticed NONE - plus she threw up shortly after ingesting it. It decreased her appetite a little - which is good, but believe me - all meds will be way,way up out of reach from now on. I wish you all could see the med bottle - she really chewed a LOT to get into it.
