A bland diet of boiled white rice mixed with plain boiled chicken is the go-to food for dogs with diarrhea. The standard ratio is 75% white rice to 25% lean protein, served in small, frequent meals throughout the day. Most cases of uncomplicated diarrhea resolve within a few days on this simple diet, but what you feed during that window matters for your dog’s comfort and recovery.
The Standard Bland Diet
The combination of boiled white rice and boiled skinless, boneless chicken breast is the most widely recommended home meal for a dog with an upset stomach. White rice is easy to digest and helps firm up stool, while lean chicken provides protein without adding excess fat that could further irritate the gut. Lean ground beef, particularly sirloin, works as a substitute if your dog doesn’t tolerate chicken.
Preparation is straightforward: boil the chicken or beef thoroughly with no seasoning, oil, butter, or garlic. Boil the rice in plain water. Mix them at that 75/25 ratio and let the food cool to slightly warm before serving. You can make a batch ahead and store it in the refrigerator for up to 72 hours.
Rather than feeding two large meals, split the daily amount into three or four smaller portions. Smaller meals are gentler on an irritated digestive tract and less likely to trigger another round of loose stool. Start with about half your dog’s normal food volume for the first day, then gradually increase to the full amount if things are improving.
Pumpkin and Fiber
Plain canned pumpkin (not pumpkin pie filling, which contains sugar and spices) is one of the most useful additions to a diarrhea diet. It contains soluble fiber that absorbs excess water in the intestines, helping firm up loose stool. The American Kennel Club recommends 1 to 4 tablespoons per meal, starting on the lower end to avoid overdoing the fiber. For a small dog, one tablespoon is plenty. Larger breeds can handle closer to four.
You can stir the pumpkin directly into the rice and chicken mixture. Most dogs find the taste appealing, so getting them to eat it is rarely a problem.
Keeping Your Dog Hydrated
Diarrhea pulls water out of the body fast, and dehydration is the most immediate risk, especially for small dogs and puppies. Fresh water should be available at all times. If your dog is reluctant to drink, bone broth can help. Its savory flavor encourages dogs to take in more fluid naturally, and it contains electrolytes that support fluid balance and nerve function.
Make or buy bone broth with no onion, garlic, or added salt. You can serve it on its own, slightly warmed, or pour it over the bland diet to make the meal more appealing to a dog with a reduced appetite.
If Your Dog Has a Chicken Allergy
Some dogs have food sensitivities to common proteins like chicken or beef. If that’s the case, the bland diet approach still works, but you’ll need a novel protein your dog hasn’t been exposed to regularly. Options include boiled white fish (like cod or tilapia), turkey, or rabbit, all prepared the same way: plain, thoroughly cooked, no seasoning.
For dogs with confirmed or suspected food allergies that also have recurring digestive problems, veterinary prescription diets use hydrolyzed proteins. These are proteins broken down into pieces so small that the immune system doesn’t recognize or react to them. Brands like Purina Pro Plan EN and Royal Canin digestive formulas use highly digestible protein sources, controlled fat levels, and specific fiber blends designed to ease the burden on a sensitive gut. These require a prescription but are worth discussing with your vet if bland diets alone aren’t cutting it.
Do Probiotics Help?
Probiotics are a popular recommendation, but the evidence is modest. A randomized, placebo-controlled trial published in Frontiers in Veterinary Science tested a multi-strain probiotic containing Lactobacillus and Bifidobacterium species in 60 dogs with acute diarrhea. Dogs on the probiotic reached normal stool consistency in an average of 3.5 days, compared to 4.8 days for the placebo group. That’s a difference of just over a day, and it wasn’t statistically significant.
That doesn’t mean probiotics are useless. They’re unlikely to cause harm, and some dogs do seem to respond well to them. If you want to try one, look for a product specifically formulated for dogs rather than a human supplement, and choose one with multiple bacterial strains. Just don’t expect it to be a dramatic fix on its own.
Transitioning Back to Regular Food
Once your dog’s stool has been firm for a full day or two, it’s time to reintroduce their normal diet. The key is doing this gradually over four to five days. A sudden switch back to regular kibble is one of the most common reasons diarrhea returns.
The transition works in 25% increments. On day one, mix 75% bland diet with 25% regular food. If stools stay firm, move to a 50/50 split the next day. Then 25% bland and 75% regular. By day four or five, you should be back to 100% normal food. If loose stool returns at any point during the transition, drop back to the previous ratio for another day before moving forward again.
Signs That Need Veterinary Attention
Most mild diarrhea from dietary indiscretion, stress, or a minor bug resolves on its own with bland food and time. But certain signs point to something more serious. Black or tarry stool indicates partially digested blood in the digestive tract. Fresh red blood in the stool, persistent vomiting alongside the diarrhea, complete loss of appetite, or noticeable lethargy all warrant a call to your vet. The same goes for diarrhea that hasn’t improved within 48 to 72 hours on a bland diet. Puppies, senior dogs, and dogs with existing health conditions have less margin for error and should be seen sooner rather than later.
