Poor Biscuit! This diarrhea could be caused by a GI illness, eating something rotten, intestinal parasites, a change in diet, or a foreign body. These causes would also lead to Biscuit vomiting. If he isn't up to date on his deworming treatments, I would get one from the vet. You can try a home remedy to see if that helps with the diarrhea before taking him into the vet. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.
