Is pumpkin good for dogs with an upset stomach?

Plain pumpkin can help dogs with a mild upset stomach, especially when the trouble is loose stools or mild constipation. Pumpkin carries two kinds of fibre: soluble fibre soaks up excess water and firms loose stools, while insoluble fibre adds bulk that gets a sluggish gut moving again.

Plain cooked or tinned pumpkin stirred into your dog's usual food is the easiest way to give it. For owners who'd rather not open a tin, a daily chew with dried pumpkin in it, like the Marleybones Gut Health Supplement, is a ready-made way to add pumpkin to the bowl.

Pumpkin is mostly water and low in calories: plain tinned pumpkin has about 34 kcal and 2.9 g of fibre per 100 g, according to USDA food data. It also brings beta-carotene, which a dog's body turns into vitamin A, plus vitamin C and potassium. Pumpkin in dog food is there for the same reasons.

There's little research on pumpkin itself for dogs' upset stomachs, so the advice rests on what fibre does. A 2022 veterinary review of dietary fibre describes vets using fibre to help manage diarrhoea and constipation in dogs. It also notes that the type of fibre in a dog's diet matters. A level tablespoon of tinned pumpkin holds under half a gram of fibre. That makes pure pumpkin a gentle way to help settle a dog's stomach after a mild upset, rather than a treatment.

How much pumpkin should I give my dog for an upset stomach?

Give a dog under 10 lbs (4.5 kg) 1–2 teaspoons of plain pumpkin a day, rising to 2–4 tablespoons a day for a dog over 60 lbs (27.2 kg). Mix it into your dog's usual food and start at the low end of the range for their size, building up gradually. Stop after two or three days, or sooner once their poo is firm again.

The Marleybones Gut Health Supplement is dosed by the chew instead: 1 chew a day for dogs under 10 kg, 2 for dogs of 10–25 kg and 3 for dogs of 25–40 kg.

What is the best pumpkin for dogs with an upset stomach?

The best pumpkin for dogs with an upset stomach is plain and 100% pure. Use plain, cooked pumpkin (either steamed, baked, or pureed). Avoid any products that contain added sugar, salt, or spices, as these can be harmful to dogs. If using tinned (canned) pumpkin, ensure it's 100% pure pumpkin with no additives.

The Marleybones Gut Health Supplement pairs dried pumpkin with psyllium husk, another natural fibre, and two prebiotics, chicory root and MOS (which comes from yeast), to support stool consistency. It's a daily chew for dogs over six months.

Pumpkin pie filling isn't suitable: it has added sugar and spices. Sugar-free versions of sweet foods can also contain xylitol, a sweetener that is poisonous to dogs.

To cook fresh pumpkin, peel it, scoop out the seeds and stringy middle, then steam or boil the flesh until soft and mash it with nothing added. Spare portions freeze well in an ice-cube tray. Plain pumpkin powders made for dogs are fine too, as long as pumpkin is the only ingredient.

What else should I feed a dog with an upset stomach?

Keep feeding a dog with an upset stomach, just less at a time: three or four small meals a day of plain, easily digested food, with fresh water always down. A dog already eating a gently cooked fresh food can usually stay on it in smaller portions. Otherwise, plain boiled chicken or white fish with a little white rice will do for a few days.

Once the tummy has settled, the everyday diet matters more than any spoonful of pumpkin, especially for a dog whose stomach is often upset. The best food for a dog with a sensitive stomach is one consistent, easily digested food with a single protein and a short ingredient list, so there's less for the gut to react to, which is how Marleybones Pantry Fresh® is made.

"Great customer service & food really suits both my dogs who have delicate stomachs." - Jacqueline, Trustpilot, October 2026

Gently cooked fresh food suits a sensitive tummy because it's soft, moist and simple. It's around 65–75% water, against about 10% in dry kibble, and it's made from real, recognisable ingredients cooked gently rather than at high heat.

Every Marleybones recipe is single-protein: Chic Chicken, for example, uses chicken as its only protein. One protein makes it easy to keep one consistent food in the bowl and spot anything that doesn't agree with your dog.

Make any change of food gradually, over 7 to 10 days, and wait until your dog's poo is back to normal before you start.

Does pumpkin help dogs with vomiting?

Pumpkin won't stop a dog vomiting. Its fibre works on stools further down the gut, not on nausea, so a dog that's throwing up needs fresh water and small, plain meals rather than a spoonful of pumpkin.

As soon as your dog is keeping water down, the first meals after being sick should be small and plain, building back up to normal portions over a day or two. If there's diarrhoea as well, a little pumpkin can go into those meals once the vomiting has stopped.

Does pumpkin help with diarrhoea and constipation?

Pumpkin can help with both mild diarrhoea and mild constipation in dogs. Most mild bouts of diarrhoea clear up within a day or two, and a little pumpkin can help firm stools along the way; for mild constipation, the same fibre adds bulk that helps things move.

Signs that pumpkin is helping are firmer, better-formed poos and your dog's appetite and energy coming back. Pumpkin eases loose stools without dealing with whatever caused them, so for a dog who keeps getting diarrhoea, finding the cause of the diarrhoea matters more than any home remedy.

For a constipated dog, water matters as much as pumpkin, because fibre needs water to work. Keep the water bowl topped up, add a splash of water to meals and keep up gentle walks, which help get things moving.

Can pumpkin upset a dog's stomach?

Yes, too much pumpkin can upset a dog's stomach. A sudden jump in fibre can make stools looser rather than firmer and give your dog wind, so piling in more pumpkin won't settle a tummy any faster.

Only feed the cooked flesh. Raw pumpkin is hard for dogs to digest, and the tough skin, stalk, stringy guts and whole seeds can upset the stomach or get stuck. A carved Halloween pumpkin that's been sitting out can go mouldy too, so keep it out of reach.

If your dog has a health condition or eats a prescription diet, check with your vet before adding pumpkin. Some conditions, such as kidney disease, need the whole diet balanced carefully.

When should I call the vet?

Call your vet if your dog's upset stomach isn't better within 48 hours, or sooner if it's getting worse. Go straight away for blood in their poo or vomit, repeated vomiting, lethargy, pale gums, a swollen or painful tummy, straining without passing anything, refusing food or water, or if you think they've eaten something poisonous.

Puppies, older dogs and dogs with a health condition dehydrate faster, so don't wait the full 48 hours with them.

Most of the usual causes of an upset stomach in dogs are minor: a change of food, scavenging, stress or parasites. An underlying illness can look the same at first, though, so a tummy that won't settle needs checking.

FAQs

Can dogs eat pumpkin?

Yes, dogs can eat plain, cooked pumpkin as a little extra in their food or an occasional treat. Pumpkin should stay a small part of the bowl, with your dog's complete food doing the main job.

Can I give my dog pumpkin every day?

Yes, a small spoonful of plain pumpkin every day is fine for most healthy dogs. For something daily without opening tins, the Marleybones Gut Health Supplement is a chew made for everyday use, to support stool consistency.

Can puppies have pumpkin?

Yes, puppies can have a little plain, cooked pumpkin once they're eating solid food. Start with the lowest amount for their weight, mixed into their usual food.

Is pumpkin a prebiotic or a probiotic for dogs?

Pumpkin isn't a probiotic, because it contains no live bacteria. Its soluble fibre feeds the good bacteria already in your dog's gut, which is why pumpkin is often called a prebiotic.

Is pumpkin or rice better for a dog with diarrhoea?

Pumpkin and rice do different jobs, so they work well together. Plain white rice is easy to digest and makes a gentle base for a bland meal, while a spoonful of pumpkin adds fibre to help firm stools.

Is pumpkin or sweet potato better for dogs?

For an upset stomach, pumpkin is the gentler choice, because it's lower in calories and higher in water. Plain cooked sweet potato is fine for dogs too, but it's starchier, so it adds more energy to the bowl.
