My 12 yr old Chow mix has loose, mushy yellow stools. could this be a food allergy? one of his liver enzymes is elevated, but not the other. He has been checked for addison’s disease, negative. his stool has been tested for O and P, I don’t know the results yet, grrr.
I feed him Nutro senior for large breeds. Any ideas for an alternate food would be appreciated. not sure if I need to eliminate grain, or go low protein?

Thanks, Jan
