He might have eaten something spoiled that is causing this. offer him boiled boneless chicken and rice every 4 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If the diarrhea does not resolve, take him to the vet to get treatment.

    It could be the food. Whenever there is a sudden change in diet, it can cause diarrhea. I can give you a home remedy for Cody that may help. Withhold food for 6 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. Best of luck.
