It sounds like Dasher is suffering from gastroenteritis. Some of the more common causes of gastroenteritis include intestinal parasites, gastritis (inflammation of the stomach wall), pancreatitis, dietary indiscretion, or a foreign body/blockage. Since Dasher has been sick for so many days I would recommend taking him to the vet. He may be dehydrated and need fluids as well as some antinausea medication to get him to eat and some antibiotics to help clear up the diarrhea.
