We got back from the vet a little while ago. Mickey tested negative for Giardia and Coccidia (Thank God!) The vet said that it is probably just a little stomach bug that he could have picked up anywhere- out on a walk or at the dog park. He gave Mickey and anti- diarreah shot, and sent us home with some mets and some paste that is simialar to nutrical. Mickey should be back to normal in no time!
