A bland diet should be easily digestible by your dog's GI tract. It allows your dog to obtain nutrition without further aggravating their already upset stomach. Bland diets are most often composed of just a single protein and carbohydrate. Sometimes vegetables can be added to the mix as a fiber source, but they aren't necessary.

Dogs with sensitive stomachs may be unable to digest some protein sources or large quantities of fat, so stick to easily digested proteins – chicken and lamb are two good choices – and avoid high-fat dog foods and table scraps.
