When a dog has loose stool or has vomited, changing the entire diet immediately is not always the answer. The safest feeding plan depends on whether the dog is otherwise bright and hydrated, how often vomiting occurs and whether there are medical conditions that make missed meals risky.
For a mild upset stomach
If an adult dog is otherwise well, your veterinarian may recommend short-term, easily digestible meals or a veterinary gastrointestinal diet. Small portions can be gentler than one large meal. Homemade chicken and rice is not nutritionally complete as a long-term diet; ask how long it should be used and when to return to a complete-and-balanced food.
Hydration comes first
Offer clean water and watch for repeated vomiting, a dry or tacky mouth, weakness and reduced urination. Never force fluids into a dog who cannot keep them down. A puppy, diabetic dog, or dog with kidney disease may require a different feeding plan and should not be fasted on generic internet advice.
Foods and products to avoid
Skip rich table scraps and abrupt treats while symptoms continue. Avoid ingredients known to be toxic to dogs, such as chocolate, grapes, raisins, onion, garlic and xylitol. Over-the-counter human stomach medicines can be unsafe or mask an important problem. Ask a veterinarian before giving them.
Know when food is not the solution
Vomiting with bloody diarrhea, severe belly pain, marked lethargy, collapse or an inability to drink deserves urgent veterinary assessment. Persistent or recurrent diarrhea should be evaluated rather than repeatedly trying new foods. See safe home-care basics and emergency signs.
