What To Do If Your Dog Has An Upset Stomach

Just like humans, dogs can experience upset stomachs from time to time. While occasional digestive issues aren’t usually a cause for concern, persistent symptoms could indicate a bigger problem. Whether it’s a mild case of nausea or something more serious, knowing why your dog has an upset stomach and how to help them feel better is essential for every pet parent.

So, why does my dog have an upset stomach? There are several possible reasons, including eating something they shouldn’t, food intolerances, infections, or even stress. Some dogs have naturally sensitive stomachs, while others develop digestive issues due to a low-quality diet filled with artificial additives and fillers.

If your dog frequently suffers from stomach problems, it might be time to take a closer look at their food. Highly processed kibble can be tough on digestion, while fresh, human-grade meals like Ollie are made with wholesome, natural ingredients that support gut health and help prevent stomach issues before they start.

In this article you’ll learn everything you need to know about helping your dog to recover from an upset stomach!

Key Takeaways

• Dogs can get upset stomachs from diet changes, eating something harmful, or underlying health issues. Identifying the cause is key to proper treatment.
• Mild cases can often be treated at home with fasting, a bland diet, and hydration, but severe symptoms require vet attention.
• Low-quality diets can contribute to chronic stomach issues. Switching to a highly digestible fresh dog food like Ollie provides can help prevent digestive problems naturally.

Why Does My Dog Have an Upset Stomach?

Dogs can get upset stomachs for many reasons, ranging from mild digestive discomfort to more serious health concerns. Understanding the cause can help you determine whether home care is enough or if a vet visit is necessary.

Common Causes of Upset Stomach in Dogs

Eating Something They Shouldn’t (Dietary Indiscretion)

Dogs are naturally curious and often eat things that aren’t good for them, like spoiled food, trash, or even non-food items. This can lead to vomiting, diarrhea, or an irritated digestive tract.

Sudden Diet Changes

Switching your dog’s food too quickly can cause stomach upset. A gradual transition over 7–10 days helps their digestive system adjust.

Food Intolerances & Allergies

Some dogs have trouble digesting certain ingredients like:

• Low-quality fillers (corn, wheat, soy) commonly found in kibble
• Artificial additives & preservatives
• Dairy or fatty foods

A fresh, high-quality diet like Ollie eliminates artificial ingredients and uses gently cooked, whole foods that are easier to digest, making it ideal for dogs with sensitive stomachs.

Bacterial or Viral Infections

Dogs can pick up stomach bugs from contaminated water, spoiled food, or exposure to other sick animals. Common infections include:

• Gastroenteritis (stomach inflammation)
• Parvovirus (a serious, contagious virus)
• Salmonella or E. coli from raw or undercooked food

Parasites (Worms & Giardia)

Intestinal parasites can cause chronic diarrhea, vomiting, and weight loss. Regular deworming and vet check-ups help prevent these issues.

Stress or Anxiety

Just like in humans, stress can affect a dog’s digestive system. Changes in routine, travel, or separation anxiety can trigger nausea, diarrhea, or loss of appetite.

More Serious Health Issues

In some cases, an upset stomach can signal an underlying problem, such as:

• Pancreatitis (inflammation of the pancreas)
• Inflammatory bowel disease (IBD)
• Liver or kidney disease

If your dog’s symptoms persist for more than 24 hours or seem severe, consult a vet.

Signs & Symptoms of an Upset Stomach in Dogs

An upset stomach in dogs can present in many ways. Some cases are mild and resolve on their own, while others may indicate a more serious issue requiring veterinary care.

Common Symptoms of an Upset Stomach

• Vomiting – A single episode may not be concerning, but frequent or severe vomiting could indicate an infection, poisoning, or another underlying issue.
• Diarrhea – Loose or watery stools can result from food changes, stress, or infections. If diarrhea is persistent or contains blood, consult a vet.
• Excessive Drooling – Dogs with nausea often drool more than usual.
• Loss of Appetite – A temporary decrease in appetite is common, but refusing food for more than 24 hours may indicate a more serious issue.
• Gassiness or Bloating – Mild gas is normal, but excessive bloating or discomfort could signal something more serious, such as bloat (GDV), which requires immediate medical attention.
• Lethargy – A dog with an upset stomach may seem less energetic or reluctant to play.

When to Call the Vet

Most mild stomach issues improve within a day, but seek veterinary care if you notice:

• Frequent or uncontrollable vomiting or diarrhea
• Blood in vomit or stool
• Signs of dehydration (dry gums, sunken eyes, excessive panting)
• Severe bloating or a hard, painful stomach
• Weakness or collapse

If your dog’s stomach issues are frequent, it may be a sign of an underlying dietary sensitivity or poor digestion caused by low-quality food. Processed kibble often contains artificial additives and hard-to-digest fillers, which can upset a dog’s stomach. Switching to a human grade diet like Ollie can help promote better digestion and overall gut health.

What Can You Give a Dog for an Upset Stomach?

If your dog has mild stomach discomfort, there are several safe, vet-approved remedies that can help settle their digestive system. However, before giving anything, it’s important to identify the cause of their upset stomach and monitor their symptoms to ensure they don’t worsen.

1. Temporary Fasting

In some cases, giving your dog’s stomach time to rest can help. A short fast (12–24 hours) may allow their digestive system to recover, but always provide access to fresh water to prevent dehydration. Fasting is generally not recommended for puppies, senior dogs, or dogs with health conditions—consult your vet before withholding food.

2. Ice Chips or Small Amounts of Water

Dogs with upset stomachs may be hesitant to drink, but staying hydrated is crucial. Instead of letting them gulp large amounts of water (which may cause more vomiting), try offering:

• Ice chips to lick slowly
• Small sips of water every 30–60 minutes
• Bone broth to encourage hydration while providing nutrients

3. Bland Diet for Digestive Relief

After fasting (if applicable), slowly introduce a bland diet that’s easy on the stomach. Some vet-recommended options include:

• Boiled chicken and white rice – Simple, low-fat, and gentle on digestion
• Pumpkin puree – A great source of fiber that can help with both diarrhea and constipation
• Plain boiled potatoes or sweet potatoes – Easily digestible carbs to soothe the stomach
• Bone broth – Provides hydration and essential nutrients without irritating the stomach

Avoid seasonings, butter, or oils, as these can make stomach issues worse.

4. Probiotics & Digestive Enzymes

Probiotics help restore healthy gut bacteria and can speed up recovery from stomach upset. Options include:

• Probiotic supplements made for dogs
• Plain, unsweetened yogurt (for dogs that tolerate dairy)
• Fermented foods like kefir (in small amounts)

Long-term gut health starts with diet. Many commercial kibbles lack natural probiotics and fiber, making them harder to digest. Switching to a fresh, high-quality food like Ollie provides natural prebiotics and probiotics to support a healthier digestive system.

5. Herbal or Natural Remedies

Certain natural remedies may help settle an upset stomach:

• Ginger – Known for reducing nausea and improving digestion
• Chamomile or peppermint tea (cooled) – Can help with mild stomach irritation
• Slippery elm bark – A natural anti-inflammatory for the digestive tract

Always check with your vet before using herbal remedies, especially if your dog is on medication.

What NOT to Give a Dog With an Upset Stomach

While home remedies can be helpful, some common human treatments can do more harm than good. Avoid giving your dog:

• Pepto-Bismol or human antacids unless directed by a vet
• Fatty, greasy, or spicy foods
• Dairy products (many dogs are lactose intolerant)
• High-fiber foods too soon, as they can worsen diarrhea if introduced too early

When to Transition Back to Regular Food

Once your dog’s stomach has settled, gradually transition them back to their regular diet over 2–3 days. If your dog frequently suffers from stomach issues, it may be time to reassess their food. Highly processed kibble can contain artificial additives and hard-to-digest fillers that trigger digestive upset. Switching to a fresh, gently cooked diet like Ollie can help maintain gut health and prevent future stomach problems.

How to Prevent Future Stomach Issues in Dogs

While an occasional upset stomach is normal, frequent digestive problems may indicate a deeper issue. Many stomach troubles can be prevented with the right diet, proper hydration, and a few simple lifestyle changes.

One of the biggest factors in digestive health is the quality of your dog’s food. Many commercial dog foods contain artificial additives, preservatives, and low-quality fillers that can be difficult for dogs to digest. Poor ingredients often lead to chronic stomach sensitivity, bloating, or inconsistent stools. Switching to a fresh, whole-food diet like Ollie eliminates artificial ingredients and provides gently cooked, highly digestible proteins and fiber, which can improve digestion and reduce stomach issues.

If you need to transition your dog to a new food, doing so slowly over 7 to 10 days is crucial. Abrupt diet changes can cause vomiting or diarrhea, as a dog’s digestive system needs time to adjust. A proper transition allows gut bacteria to adapt to new ingredients, reducing the risk of stomach upset.

In addition to feeding a high-quality diet, it’s important to keep harmful foods out of reach. Dogs are curious and often eat things they shouldn’t, leading to digestive distress. Some of the most common dietary causes of stomach upset include:

• Greasy or fatty foods – Can trigger pancreatitis and diarrhea.
• Spicy or highly seasoned foods – May cause irritation and discomfort.
• Toxic ingredients like chocolate, onions, garlic, and xylitol – Even small amounts can be dangerous.

Hydration also plays a key role in digestion. Dogs should always have access to fresh, clean water, as dehydration can worsen stomach issues. If your dog is reluctant to drink, adding moisture-rich foods like bone broth can help keep them hydrated while soothing the digestive tract.

Supporting gut health with probiotics and fiber can also help prevent stomach issues. Probiotics promote a balanced gut microbiome, while fiber supports digestion and stool consistency. Rather than relying on synthetic supplements, choosing a fresh, whole-food diet like Ollie naturally provides these gut-friendly nutrients, leading to better digestion over time.

Finally, regular veterinary checkups are essential, especially if your dog frequently experiences digestive issues. Chronic stomach problems could signal food allergies, inflammatory bowel disease, or even a more serious underlying condition. A vet can help identify the root cause and recommend dietary or medical solutions to keep your dog healthy.

By focusing on high-quality nutrition, hydration, and digestive support, you can take proactive steps to prevent stomach issues before they start. Ensuring your dog eats a nutrient-rich, easily digestible diet like Ollie can reduce the chances of upset stomachs and promote long-term health.

When to See a Vet for a Dog’s Upset Stomach

Most mild stomach issues resolve within 24 hours, especially if caused by something minor like eating too fast or mild dietary indiscretion. However, there are times when an upset stomach could indicate a more serious problem that requires veterinary care.

Signs That Require Immediate Veterinary Attention

If your dog experiences any of the following symptoms, contact your vet as soon as possible:

• Persistent vomiting or diarrhea lasting more than 24 hours
• Blood in vomit or stool (bright red or dark, tarry stools)
• Severe bloating or a swollen abdomen, which could indicate a life-threatening condition like gastric dilatation-volvulus (bloat)
• Signs of dehydration, including dry gums, sunken eyes, or excessive panting
• Lethargy or weakness, especially if paired with other symptoms
• Frequent dry heaving or retching without producing vomit
• Loss of appetite for more than a day, particularly in smaller or senior dogs
• Signs of poisoning, such as excessive drooling, tremors, or difficulty breathing

If your dog has chronic or recurring digestive issues, it may be a sign of food intolerances, allergies, or a deeper health concern. Many commercial dog foods contain artificial ingredients and low-quality fillers that can lead to long-term digestive distress. Transitioning to a fresh, minimally processed diet like Ollie can help eliminate common food triggers and promote better gut health.

What to Expect at the Vet

If your dog needs veterinary care, the vet will likely:

• Perform a physical exam and check for abdominal pain or bloating.
• Ask about recent diet changes, exposure to toxins, or new treats/foods.
• Recommend diagnostic tests such as bloodwork, X-rays, or a fecal exam to check for infections, parasites, or underlying conditions.
• Provide treatment, which may include anti-nausea medication, fluids for dehydration, or a specialized diet plan.

For dogs with chronic digestive issues, your vet may suggest a diet tailored to sensitive stomachs. Addressing an upset stomach early and feeding a high-quality, easily digestible diet can prevent future issues and keep your dog feeling their best.
