You can give a couple of tablespoons of PLAIN 100% canned pumpkin. NOT the pumpkin pie mix with spices in it, just pumpkin. It helps to relieve the diarrhea. Give about 2 Tbs with the rice or each meal for the next couple of days. You can also mix in some cooked ery lean beef or chicken with the rice for a day or two if you want to wait to move him back to his regular kibble.
