You can consider stopping both foods and feeding boiled skinless chicken or hamburger with plain rice. The addition of a probiotic like Fortiflora would also help regulate any disruptions to the GI tract. After a few days, slowly resume whatever diet you intend on feeding regularly. If diarrhea persists in spite of this, the addition of an anti-diarrheal and/or anti-inflammatory drug may be required.
