What to Do If Your Dog Has an Upset Stomach

A dog with an upset stomach is a common concern for pet owners. One minute, your pup seems perfectly fine, and the next, they may be vomiting, refusing food, or experiencing diarrhea. While occasional digestive upset is normal, persistent symptoms can be a sign of underlying health issues or dietary problems that need attention.

Dogs can develop an upset stomach for many reasons, including eating something they shouldn’t, sudden diet changes, food sensitivities, bacterial infections, or stress. In most mild cases, symptoms can be treated at home with simple remedies, but some situations require immediate veterinary care.

In this guide, we’ll walk through the common causes, symptoms, treatment options, and prevention methods for dog stomach issues. We’ll also discuss why diet plays a crucial role in digestive health and how feeding a fresh, high-quality diet like Spot & Tango can help reduce stomach problems long-term. Many commercial dog foods contain low-quality fillers, artificial additives, and hard-to-digest ingredients, which can lead to recurring digestive issues. A fresh, whole-food diet provides the nutrients dogs need to support a healthy gut, balanced digestion, and overall well-being.

By the end of this article, you’ll have a comprehensive understanding of how to help your dog recover from an upset stomach and how to prevent future digestive problems through better nutrition.

Common Causes of an Upset Stomach in Dogs

Dogs can develop an upset stomach for many reasons, ranging from something as simple as eating too fast to more serious health conditions. Understanding the underlying cause can help you determine whether your dog needs home treatment or veterinary care.

One of the most common causes is dietary indiscretion, which happens when dogs eat spoiled food, garbage, table scraps, or even non-food objects like socks or toys. This can lead to vomiting, diarrhea, and discomfort. Sudden changes in diet—such as switching to a new dog food too quickly—can also disrupt the digestive system, causing stomach upset.

Food allergies and intolerances are another culprit. Many commercial dog foods contain low-quality ingredients, artificial additives, and fillers that can trigger digestive issues in sensitive dogs. Some ingredients, like grains, dairy, or certain proteins, may cause chronic stomach problems if a dog has an intolerance.

Bacterial or viral infections, such as salmonella or parvovirus, can also cause severe stomach distress. If your dog has persistent vomiting, diarrhea, fever, or extreme lethargy, these could be signs of an infection that requires immediate vet attention. Parasites, including worms and Giardia, can also disrupt digestion, leading to bloating, diarrhea, and weight loss.

Stress and anxiety can contribute to stomach issues as well. Dogs experiencing separation anxiety, changes in routine, or high-stress situations may develop nausea, vomiting, or diarrhea due to the gut-brain connection.

For dogs with chronic digestive problems, conditions like pancreatitis, inflammatory bowel disease (IBD), or gastritis could be to blame. These issues often require dietary management and veterinary guidance to prevent ongoing discomfort.

Common Causes of an Upset Stomach in Dogs:

Dietary indiscretion (eating garbage, spoiled food, or non-food objects)
Sudden diet changes (switching food too quickly)
Food allergies or intolerances (low-quality ingredients, grains, or proteins)
Bacterial or viral infections (salmonella, parvovirus)
Parasites (worms, Giardia)
Stress or anxiety (changes in routine, separation anxiety)
Chronic conditions (pancreatitis, IBD, gastritis)

Since diet plays a major role in digestive health, feeding a high-quality, fresh dog food diet can help prevent many stomach issues before they start. Fresh, whole ingredients are easier to digest and free from artificial additives that can irritate the gut and trigger sensitivities.

Dog Upset Stomach Symptoms: How to Recognize the Signs

A dog’s upset stomach can present in different ways, from mild digestive discomfort to more serious health concerns. Recognizing the signs early can help you decide whether your dog needs home care or veterinary attention.

One of the most common symptoms is vomiting, which can range from occasional regurgitation to frequent episodes. Occasional vomiting might not be a cause for concern, especially if your dog ate too quickly or consumed something slightly irritating. However, persistent vomiting, vomiting blood, or vomit with a foul odor could indicate a serious underlying issue such as an infection, toxin ingestion, or gastrointestinal disease.

Diarrhea is another key sign of stomach distress. Loose stools may be caused by a minor dietary upset, while persistent diarrhea or stools containing mucus or blood could signal parasites, bacterial infections, or inflammatory bowel disease. Dehydration can quickly become a risk if diarrhea is prolonged, so it’s essential to monitor your dog’s water intake and check for signs of dehydration like dry gums or lethargy.

Dogs with an upset stomach often show changes in appetite. Some dogs refuse food entirely, while others may eat less than usual. A temporary loss of appetite can be normal, but if your dog hasn’t eaten for more than 24 hours, it could be a sign of a more serious digestive problem.

Other signs of stomach discomfort include excessive gas, burping, stomach gurgling, and drooling. Some dogs will also lick their lips repeatedly or eat grass to induce vomiting in an attempt to relieve nausea. If your dog seems restless, uncomfortable, or frequently assumes the "prayer position" (front legs stretched forward, rear end raised), this could indicate abdominal pain or bloating, which requires immediate veterinary attention.

Signs Your Dog Has an Upset Stomach:

Vomiting (occasional vs. persistent, with or without blood)
Diarrhea (mild vs. severe, with mucus or blood)
Loss of appetite or refusing food
Excessive gas, burping, or stomach gurgling
Drooling or licking lips excessively
Eating grass in an attempt to vomit
Lethargy or signs of dehydration (dry gums, sunken eyes)
Abdominal pain or bloating (prayer position, restlessness)

While mild stomach upset often resolves on its own, prolonged symptoms can indicate a serious health issue. Feeding a high-quality, fresh diet like Spot & Tango’s can help prevent chronic digestive issues by providing easily digestible ingredients free from artificial additives and fillers that often cause stomach sensitivities.

What Can I Give My Dog for an Upset Stomach?

If your dog has mild stomach upset, home remedies and dietary adjustments can often help soothe their digestive system. However, it’s essential to introduce any treatment carefully and monitor your dog’s response.

One of the first steps is short-term fasting (for 12 to 24 hours, depending on your dog’s size and health). This allows the digestive system to rest and recover. Small dogs and puppies should not fast for extended periods, as they are more prone to low blood sugar levels.

After fasting, offering a bland diet can help settle the stomach. Boiled chicken and plain white rice are commonly recommended because they are easy to digest and gentle on the stomach. Pumpkin or plain sweet potatoes are also beneficial, as they provide soluble fiber that helps firm up loose stools and regulate digestion. Avoid adding any seasonings, butter, or oils, as these can further irritate the stomach.

Bone broth is another excellent option, as it helps keep your dog hydrated and provides essential nutrients without overwhelming the digestive system. It’s especially useful for dogs who are hesitant to eat after an upset stomach.

For dogs with ongoing digestive sensitivities, incorporating probiotics or plain, unsweetened yogurt can help restore healthy gut bacteria. Probiotics support better digestion and immune function, reducing the likelihood of future stomach issues.

Hydration is crucial, as vomiting and diarrhea can lead to dehydration. Make sure your dog has access to fresh, clean water at all times. If your dog is reluctant to drink, offering ice cubes or diluted electrolyte solutions (vet-approved) can help maintain fluid balance.

Home Remedies for an Upset Stomach:

Short-term fasting (12–24 hours for adult dogs)
Bland diet (boiled chicken & rice, plain pumpkin, or sweet potatoes)
Bone broth (gentle on the stomach, keeps hydration levels up)
Probiotics or plain yogurt (supports gut bacteria and digestion)
Hydration support (fresh water, ice cubes, or diluted electrolyte solutions)

While these remedies can help with minor stomach issues, persistent digestive problems could be linked to food sensitivities or poor diet quality. Many commercial dog foods contain low-quality fillers, artificial additives, and hard-to-digest ingredients that contribute to stomach upset.

Dog Upset Stomach Treatment: When to See a Vet

While mild stomach issues in dogs often resolve on their own, certain symptoms may indicate a more serious condition requiring veterinary attention. Knowing when to seek professional care can help prevent complications and ensure your dog gets the treatment they need.

If your dog’s upset stomach is persistent or worsening, a vet visit is necessary. Vomiting or diarrhea that lasts more than 24 hours, especially if accompanied by lethargy or dehydration, could signal a more severe problem like gastrointestinal infections, pancreatitis, or intestinal blockages. Bloody vomit or diarrhea is a red flag that should never be ignored, as it can indicate internal bleeding, parasites, or severe inflammation.

Another major concern is bloating (gastric dilatation-volvulus or GDV), which occurs when a dog’s stomach twists and fills with gas. This condition is life-threatening and requires immediate emergency care. Signs of bloat include excessive drooling, a swollen belly, restlessness, and unsuccessful attempts to vomit.

If your dog is refusing food or water for more than a day, this could indicate a serious digestive issue or underlying illness. Rapid weight loss, weakness, and signs of pain (such as whining, restlessness, or difficulty lying down comfortably) are also reasons to call your vet.

Signs Your Dog Needs Veterinary Care:

Vomiting or diarrhea lasting more than 24 hours
Blood in vomit or stool
Severe dehydration (dry gums, sunken eyes, lethargy)
Persistent refusal to eat or drink
Swollen belly, excessive drooling, or unproductive retching (possible bloat)
Weakness, weight loss, or unusual behavior indicating pain

If your dog’s stomach issues are caused by chronic food sensitivities, a vet may recommend switching to a fresh, high-quality diet with limited, easily digestible ingredients. Many commercial kibbles contain artificial additives, fillers, and by-products that can irritate the digestive system.

Preventing Future Stomach Issues: The Role of Diet

A dog’s digestive health is closely linked to their diet, and many cases of upset stomach can be prevented by feeding high-quality, easily digestible food. Poor nutrition, artificial additives, and sudden dietary changes are common triggers for stomach issues, so making smart dietary choices can go a long way in maintaining gut health.

One of the biggest culprits behind chronic digestive issues is low-quality commercial dog food that contains fillers, artificial preservatives, and by-products. Many of these ingredients are difficult for dogs to digest and can lead to frequent stomach upset, food sensitivities, and inflammation. Switching to a fresh, whole-food diet can help reduce these issues by providing natural, high-quality ingredients that support digestion.

Avoiding table scraps and sudden diet changes is also crucial. Rich, fatty foods from human meals can cause gastrointestinal upset or even pancreatitis, a painful and dangerous condition. If switching your dog’s food, always transition gradually over 7–10 days to prevent stomach upset.

Hydration plays a vital role in digestion as well. Dogs should always have access to fresh, clean water to support proper digestion and prevent dehydration-related stomach problems.

A great way to support long-term digestive health is by incorporating gut-friendly nutrients like fiber, probiotics, and high-quality proteins into your dog’s diet. Some of Spot & Tango’s fresh dog food recipes are specifically formulated with easily digestible ingredients that promote gut health, reduce inflammation, and minimize food sensitivities. By feeding a balanced, vet-approved diet, pet parents can help prevent recurring stomach issues and keep their dog’s digestion strong and healthy.

Tips for Preventing Upset Stomach in Dogs:

Choose high-quality, easily digestible dog food (avoid fillers & artificial additives).
Introduce new foods gradually to prevent digestive upset.
Avoid feeding table scraps, especially rich or fatty foods.
Ensure your dog stays hydrated with fresh, clean water at all times.
Incorporate gut-friendly ingredients like fiber, probiotics, and lean proteins.

Since diet is one of the biggest factors affecting digestive health, choosing wholesome, nutrient-rich meals like Spot & Tango’s fresh dog food can make a significant difference in reducing stomach issues and improving your dog’s overall well-being.
