To feed a dog with diarrhea, offer a bland diet of plain boiled chicken and white rice in small, frequent portions once any short fasting period is over. Plain canned pumpkin and unsalted bone broth can help too. Always keep fresh water available, avoid fatty and seasoned foods, and see a vet if diarrhea lasts more than 48 hours or contains blood.
Key takeaways
- A bland diet of boiled chicken and white rice is the safest first food.
- Plain pumpkin adds fiber; bone broth supports hydration.
- Never withhold water, and never fast puppies, seniors, or small dogs.
- Reintroduce regular food gradually over three to four days.
- Blood, vomiting, or diarrhea beyond 48 hours needs a vet.

What to Feed a Dog With Diarrhea: The Bland Diet Explained
Knowing what to feed a dog with diarrhea comes down to one principle: give the digestive system gentle, easy-to-digest food while it recovers. A bland diet does exactly that. It provides simple nutrition without the fat, fiber, or seasoning that can further irritate an inflamed gut. The classic combination is plain boiled chicken and white rice, and for most healthy adult dogs with mild diarrhea, it is the ideal starting point.
The goal of a bland diet is not to cure the underlying cause but to reduce the workload on the gut, firm up the stool, and keep your dog nourished and hydrated while the digestive tract settles. Diarrhea is one of the most common reasons owners contact a vet, and in many mild cases it resolves within a day or two with the right feeding approach. Below, we cover whether to fast first, the best foods, what to avoid, how to keep your dog hydrated, and how to safely return to normal meals.
Should You Fast Your Dog First?
For a healthy adult dog with mild diarrhea, a short food break of around 12 hours can allow the gut to rest. During any fast, fresh water must always be available so your dog stays hydrated.
Fasting is not appropriate for every dog. Do not withhold food from puppies, senior dogs, small or toy breeds, or dogs with existing health conditions, because they can weaken and become hypoglycemic quickly. When you are unsure, skip the fast and ask your vet. A brief rest is a tool, not a requirement, and for many dogs you can move straight to a bland diet.
The Best Foods to Feed a Dog With Diarrhea
Once any short rest is over, or right away for dogs that should not fast, introduce these gentle foods in small portions.
1. Plain Boiled Chicken
Skinless, boneless chicken breast, boiled with no oil, butter, salt, or seasoning, is gentle, lean, and protein-rich. Shred it into small pieces so it is easy to digest. Chicken is a familiar, mild protein that most dogs tolerate well.
2. White Rice
Plain, well-cooked white rice is easy on the stomach and helps firm the stool. A common starting ratio is roughly two parts rice to one part chicken. White rice is preferred over brown here because it is lower in fiber and easier to digest during a flare-up.
3. Plain Canned Pumpkin
A spoonful of plain canned pumpkin (not spiced pie filling) adds soluble fiber that can help regulate the gut and firm loose stools. Use a small amount for small dogs and a little more for larger dogs.
4. Boiled Potato or Sweet Potato
Plain, peeled, and mashed with no butter or salt, these are another gentle carbohydrate option for dogs that do not tolerate rice well.
5. Unsalted Bone Broth
Plain, onion-free, unsalted bone broth adds flavor and supports hydration, which is especially helpful if your dog is not eating much solid food yet. It can also make the bland diet more appealing to a dog with a reduced appetite.
Feed these in small, frequent portions rather than one large meal, and watch how your dog responds over the next day.

Foods to Avoid While Your Dog Has Diarrhea
Certain foods can make diarrhea worse and should be kept away until your dog fully recovers:
- Fatty foods, fried food, and table scraps
- Dairy such as milk and cheese
- Spicy or heavily seasoned food
- Their regular rich kibble until stools firm up
- Onions, garlic, grapes, raisins, and other foods toxic to dogs
- Treats, dental chews, and rawhide during recovery
Hydration: The Part Owners Often Miss
Diarrhea causes fluid loss, and dehydration is the biggest hidden risk. Always keep fresh water available. Signs of dehydration include dry or tacky gums, low energy, sunken eyes, and skin that stays “tented” when gently lifted. If you notice these, contact your vet promptly, as dehydration can become serious, especially in small dogs and puppies. In some cases a vet may recommend an electrolyte solution, but do not add anything to your dog’s water without guidance.
How to Transition Back to Normal Food
Once your dog’s stools are firm again, usually within a couple of days, reintroduce the regular diet slowly over three to four days. Start with mostly bland food and a small amount of regular food, then gradually shift the ratio each day until your dog is fully back on its usual diet. Switching too quickly is a common reason diarrhea returns, so patience here pays off. A simple schedule is: day one about 75% bland and 25% regular, then move toward 50/50, then 25/75, then fully back.
Common Mistakes to Avoid
- Feeding too much at once. Small, frequent portions are gentler than one big bowl.
- Adding butter, oil, or salt to the chicken or rice, which defeats the purpose of a bland diet.
- Rushing back to normal food, which can restart the diarrhea.
- Giving human anti-diarrhea medication, which can be dangerous without vet advice.
- Ignoring warning signs like blood or lethargy while waiting for the diet to work.
When to Call the Vet
A bland diet is fine for mild cases, but see your vet promptly if your dog shows any of these:
- Diarrhea lasting more than 48 hours
- Blood in the stool, or black, tarry stools
- Vomiting alongside the diarrhea
- Signs of dehydration
- Weakness, fever, or a painful or swollen belly
- Any diarrhea in a puppy, senior, or very small dog
These signs can point to infection, parasites, toxins, or other conditions that need proper diagnosis and treatment.
Simple Ways to Prevent Future Diarrhea
- Change foods gradually over several days, never all at once.
- Keep trash, spoiled food, and toxic plants out of reach.
- Maintain a consistent feeding routine.
- Stay up to date on deworming and vaccinations.
- Introduce new treats one at a time so you can identify what upsets the stomach.
- Change foods gradually over several days, never all at once. This applies to any switch, including moving to a fresh dog food diet.
Usually until the stool is firm, followed by a gradual transition back to normal food over three to four days. If there is no improvement within about two days, see your vet.
Some dogs tolerate a little plain, unsweetened yogurt for its probiotics, but dairy upsets others. Introduce it cautiously, or ask your vet about a dog-specific probiotic instead.
Both help. White rice is a gentle base carbohydrate, while pumpkin adds soluble fiber. Many owners use small amounts of both together.
No. Never withhold water. Dehydration is a real risk with diarrhea, so keep fresh water available at all times.
A consistent bland diet of boiled chicken and rice with a little pumpkin, fed in small portions, is the safest and most reliable approach for mild cases.
Plain, cooked (boiled or lightly scrambled without oil, butter, or salt) egg can be a gentle protein some dogs tolerate well, but introduce it in small amounts.
