Common Digestive Problems in Dogs

Vomiting, diarrhoea and general digestive upset are common problems in dogs, and many cases are mild and short-lived. Even so, tummy troubles can be worrying for owners, especially if symptoms come on suddenly or your dog seems quiet, uncomfortable or off their food.

Understanding the possible causes, knowing what you can monitor at home, and recognising when medication or veterinary support may be needed can help you respond calmly and appropriately. At Vetscriptions, we believe good pet healthcare starts with clear, practical information and responsible treatment choices.

This article is intended for general guidance only and should not replace professional veterinary advice. If your pet is unwell or showing concerning symptoms, please contact your veterinary surgeon.

What counts as digestive upset in dogs?

Digestive upset can affect the stomach, intestines or both. In some dogs, symptoms are mild and settle quickly. In others, they can become more serious, especially if there is dehydration, pain, repeated vomiting or blood loss.

Common signs of digestive problems in dogs include:

• Vomiting
• Diarrhoea
• Soft stools
• Straining to pass faeces
• Excessive wind
• Lip licking, drooling or signs of nausea
• Reduced appetite
• Abdominal discomfort or bloating
• Tiredness or low energy

Some dogs may also eat grass, seem restless, or adopt a hunched posture if they are feeling sick or uncomfortable.

Common causes of vomiting and diarrhoea in dogs

There are many possible reasons for digestive upset. Some are relatively minor, while others need prompt veterinary attention.

Dietary indiscretion

This simply means your dog has eaten something unsuitable. It is one of the most common causes of vomiting and diarrhoea. This could include:

• Food from the bin
• Table scraps or rich foods
• Sudden changes in diet
• Spoiled food
• Foreign materials such as wrappers, toys or bones

Sudden diet change or food intolerance

Changing food too quickly can upset your dog’s digestive system. Some dogs also have sensitivities to certain ingredients, which may lead to ongoing loose stools, wind, skin issues or intermittent vomiting. If your dog needs a more sensitive feeding approach, it can help to review suitable options within our dog food and treats and dog digestion ranges, ideally alongside advice from your vet.

Parasites

Intestinal worms and other parasites can cause diarrhoea, weight loss, poor condition or tummy discomfort. Regular parasite prevention is an important part of routine care. You can browse our flea, tick & worming collection or dog flea and worming products if you are checking your dog’s preventative treatment plan.

Infections

Bacterial, viral or other infections can affect the gut and may cause vomiting, diarrhoea and lethargy. Puppies are especially vulnerable and can become dehydrated more quickly than adult dogs.

Stress or anxiety

Some dogs develop digestive upset during times of stress, such as travel, kennels, fireworks, changes at home or separation from their owner. If anxiety seems to be a factor, supportive management may help, and some owners find it useful to explore products in our dog anxiety or dog pheromones collections.

Underlying health conditions

Repeated or ongoing digestive signs can sometimes be linked to longer-term conditions such as pancreatitis, liver disease, hormone disorders, inflammatory bowel disease or problems affecting other organs. Dogs with recurrent symptoms may need veterinary tests to find the cause.

When should you contact a vet?

While a single episode of mild vomiting or a short bout of diarrhoea may not always be an emergency, there are times when you should seek veterinary advice promptly.

Contact your veterinary surgeon if your dog:

• Vomits repeatedly or cannot keep water down
• Has severe or persistent diarrhoea
• Has blood in their vomit or faeces
• Seems weak, collapsed or very lethargic
• Has a swollen or painful abdomen
• May have eaten something toxic or caused a blockage
• Is a puppy, elderly dog, or has another medical condition
• Shows signs of dehydration, such as dry gums or sunken eyes
• Has symptoms lasting more than 24 hours, or sooner if severe

Urgent assessment is especially important if your dog is retching without bringing anything up, as this can be a sign of gastric dilatation-volvulus, sometimes called bloat, which is a life-threatening emergency.

What can you do at home for mild digestive upset?

If your dog is bright, alert and only mildly affected, your vet may advise home monitoring. Always follow your own veterinary surgeon’s guidance, especially if your dog has had digestive problems before.

Offer fresh water

Keeping your dog hydrated is very important. Small, frequent drinks may be better tolerated than allowing gulping after vomiting.

Feed a bland or easily digested diet if advised

Some dogs benefit from a short period on a simple, easily digested food recommended by a vet. Avoid feeding rich treats, fatty foods or large meals while the stomach is unsettled.

Monitor closely

Make a note of:

• How often your dog is vomiting or passing diarrhoea
• Whether there is any blood
• What they have eaten
• Their energy levels
• Whether they are drinking normally

This information can be very helpful if you need to speak to your vet.

Do not give human medicines

Never give over-the-counter human anti-sickness, anti-diarrhoea or pain relief medicines unless your vet has specifically told you to do so. Some common human medicines can be dangerous for dogs.

When might medication help?

Not every dog with vomiting or diarrhoea needs medication, but some do. The right treatment depends on the cause, the severity of the signs, and your dog’s general health.

Your vet may prescribe medication such as:

• Anti-sickness treatment to help control vomiting
• Gut protectants or supportive digestive products
• Prescription diets for sensitive digestion
• Parasite treatment if worms or other parasites are suspected
• Fluid therapy if your dog is dehydrated
• Other prescription medicines based on the underlying cause

If your dog has been prescribed treatment, we can help you order it safely and conveniently online. You can find more information on how to order a prescription medicine, browse our prescription medicines, or read our prescription FAQs.

Digestive supplements and supportive care

In some cases, supportive digestive care may be recommended alongside diet changes or veterinary treatment. Depending on your dog’s needs, this could include products designed to support normal digestion or maintain general gut health.

Our dog supplements, dog digestion collection and own brand premium supplements may be helpful for some pets, but it is always best to check with your veterinary surgeon before starting anything new, especially if your dog is already unwell or taking other medication.

How to help prevent digestive problems

Not every digestive issue can be avoided, but a few simple steps can reduce the risk.

• Keep your dog on a consistent, balanced diet
• Change foods gradually over several days
• Avoid feeding fatty leftovers or unsuitable treats
• Keep bins, bones, string and small objects out of reach
• Stay up to date with worming treatment
• Use regular preventative healthcare appropriate for your dog’s age and lifestyle
• Arrange a vet check if symptoms keep returning

If your dog has a sensitive stomach, it may also help to choose digestive-friendly foods and supplements carefully, rather than changing products frequently.

What about cats and small pets?

Although this article focuses on dogs, digestive problems can affect other pets too. Cats with vomiting, diarrhoea or poor appetite may need prompt assessment, especially as reduced eating can become serious quite quickly in cats. Small pets such as rabbits and guinea pigs can also become very unwell if their digestion is disturbed.

If you are caring for another species, you can explore our cat collection or small animal collection for relevant healthcare products, but always contact your vet if your pet is unwell.

When ongoing digestive trouble needs further investigation

If your dog has repeated vomiting, frequent diarrhoea, weight loss, poor appetite or ongoing soft stools, it is important not to keep guessing at the cause. Chronic digestive issues often need proper veterinary investigation, which may include faecal testing, blood tests, imaging or a food trial.

Responsible pet medication use means making sure any treatment is appropriate for your dog’s individual needs, rather than relying on general remedies alone. If your vet prescribes ongoing treatment, we are here to help make the process straightforward, from completing an animal health form to arranging delivery. You can also visit our postage & delivery page or contact us if you need support with an order.

Conclusion

Vomiting, diarrhoea and digestive upset are common in dogs, and in many cases they pass quickly with sensible care and close monitoring. However, symptoms can sometimes point to infection, parasites, dietary problems or a more serious underlying condition, so it is important to know when veterinary advice is needed.

Early action, good hydration, careful feeding and responsible use of medications all play a part in helping dogs recover well. If your dog has been prescribed treatment or you are looking for supportive digestive care, you can browse our dog collection and digestive support ranges at Vetscriptions. If you are ever unsure, the safest step is to speak to your veterinary surgeon for tailored advice.
