Watching your dog struggle with vomiting, diarrhea, or a lack of appetite can be stressful for any pet parent. An upset stomach in dogs is a common problem, but it should never be ignored. While some mild digestive issues may improve with a bland diet and rest, other cases can signal more serious health concerns that require veterinary care.
Understanding what you can safely give a dog for an upset stomach is important for protecting your pet’s health and helping them recover comfortably. From over-the-counter medications to prescription treatments and supportive home care, there are several options veterinarians may recommend depending on the cause and severity of the symptoms.
Why It’s Important to Address an Upset Stomach in Dogs
Digestive problems in dogs can develop for many reasons, including dietary changes, eating spoiled food, bacterial infections, parasites, stress, or reactions to medications. In many mild cases, dogs may only experience temporary discomfort. However, persistent gastrointestinal symptoms can quickly lead to dehydration, weakness, and more severe complications.
Common symptoms of stomach upset in dogs include:
- Vomiting
- Diarrhea
- Reduced appetite
- Excessive drooling
- Lethargy
- Abdominal discomfort
- Nausea or lip licking
Early treatment can help prevent symptoms from worsening and improve recovery time. If your dog has severe vomiting, bloody stool, or symptoms lasting more than 24 hours, contact a veterinarian immediately.
Safe Home Remedies for Mild Stomach Upset
For dogs with mild symptoms who are otherwise active and alert, veterinarians often recommend supportive care before turning to stronger medications.
Feed a Bland Diet
A bland diet is one of the most effective first steps for managing mild digestive upset. Easily digestible foods help reduce strain on the gastrointestinal tract while allowing the stomach to recover.
Common bland diet options include:
- Boiled skinless chicken breast
- Plain white rice
- Boiled turkey
- Plain pumpkin puree in small amounts
Feed small portions several times throughout the day instead of one large meal. Once symptoms improve, gradually transition your dog back to their regular food over several days.
Offer Plenty of Water
Vomiting and diarrhea can quickly cause dehydration. Always make sure fresh water is available. Encourage small, frequent sips instead of allowing your dog to drink large amounts at once, which may trigger more vomiting.
Consider Probiotics
Probiotics may help restore healthy gut bacteria after digestive disturbances. Changes in the intestinal microbiome can occur after stress, illness, antibiotic use, or exposure to harmful bacteria.
Veterinary-approved probiotics may help:
- Improve stool quality
- Support digestion
- Restore healthy gut balance
- Reduce recovery time
Always choose products specifically formulated for dogs.
Over-the-Counter Medications for Dog Stomach Problems
Some human medications are occasionally recommended by veterinarians for dogs. However, pet owners should never administer medication without professional guidance because incorrect dosing or drug interactions can be dangerous.
Famotidine (Pepcid)
Famotidine is commonly used to reduce stomach acid production. It may help dogs experiencing acid irritation, mild vomiting, or stomach inflammation.
Benefits may include:
- Reducing acid reflux
- Soothing stomach irritation
- Supporting ulcer treatment
- Mild anti-nausea effects
Famotidine is usually most effective when given on an empty stomach before meals. Because it can interact with other medications, veterinary supervision is essential.
Omeprazole (Prilosec)
Omeprazole is another acid-reducing medication often prescribed for dogs with stomach ulcers or severe acid irritation. It works more powerfully than famotidine but may take several days to reach full effectiveness.
Possible concerns include:
- Drug interactions
- Altered nutrient absorption
- Changes in gut bacteria
- Mild digestive side effects
Long-term use should always be monitored by a veterinarian.
Prescription Medications Veterinarians May Recommend
Moderate or severe gastrointestinal symptoms often require prescription medications tailored to the underlying condition.
Cerenia (Maropitant)
Cerenia is widely used by veterinarians to control vomiting and nausea in dogs. It works by blocking signals in the brain that trigger vomiting.
Veterinarians commonly prescribe it for:
- Acute vomiting
- Motion sickness
- Post-surgical nausea
- Gastrointestinal inflammation
It is generally considered very safe when used appropriately.
Ondansetron (Zofran)
Ondansetron is another anti-nausea medication sometimes used in veterinary medicine. It may help dogs experiencing nausea caused by chemotherapy, anesthesia, or gastrointestinal disease.
Potential side effects are usually mild and may include:
- Sleepiness
- Constipation
- Mild sedation
Metronidazole (Flagyl)
Metronidazole has historically been prescribed for diarrhea and certain intestinal infections. However, veterinarians now use it more cautiously because it may disrupt healthy gut bacteria.
Possible risks include:
- Nausea
- Neurological side effects
- Loss of appetite
- Long-term microbiome disruption
Because of its bitter taste, many dogs dislike taking this medication.
Entyce (Capromorelin)
Dogs who stop eating during illness may benefit from appetite stimulants such as Entyce. This medication mimics hunger hormones to encourage food intake.
Maintaining proper nutrition is especially important during recovery from gastrointestinal illness.
Metoclopramide (Reglan)
Metoclopramide helps improve stomach and intestinal movement while also reducing nausea and reflux. It is commonly used in dogs recovering from surgery or experiencing slowed gastrointestinal motility.
However, it is not suitable for dogs with suspected intestinal blockages or seizure disorders.
When an Upset Stomach May Signal Something Serious
Although mild digestive upset is common, some symptoms should never be ignored. Seek veterinary care immediately if your dog experiences:
- Vomiting or diarrhea lasting longer than 24 hours
- Blood in vomit or stool
- Black, tarry stool
- Severe lethargy
- Repeated vomiting episodes
- Abdominal swelling
- Refusal to eat or drink
- Signs of pain
- Increased thirst or urination
These symptoms could indicate serious conditions such as intestinal obstruction, pancreatitis, poisoning, infections, or internal bleeding.
Medications That Can Cause Digestive Upset in Dogs
Certain medications themselves can trigger stomach irritation in dogs. Common examples include:
- NSAID pain relievers
- Antibiotics
- Anxiety medications
- Steroids
- Some parasite treatments
If your dog develops vomiting or diarrhea after starting a medication, consult your veterinarian before stopping or changing treatment.

Is Pepto-Bismol Safe for Dogs?
Pepto-Bismol is generally not recommended for dogs unless specifically instructed by a veterinarian. While some pet owners use it for mild digestive issues, it can cause complications and may interfere with diagnostic testing.
Safer and more effective alternatives are usually available through your veterinarian.
How to Support Your Dog During Recovery
Helping your dog recover from an upset stomach involves more than medication alone. Supportive care plays a major role in healing.
Helpful recovery tips include:
- Keep your dog calm and rested
- Avoid sudden diet changes
- Feed small meals
- Monitor stool and vomiting frequency
- Follow medication instructions carefully
- Schedule follow-up veterinary visits if symptoms persist
Dogs recovering from digestive illness often improve more quickly when treatment begins early and hydration is maintained.
Conclusion
An upset stomach in dogs can range from a mild digestive irritation to a sign of a more serious medical condition. While bland diets, probiotics, and veterinarian-approved medications may help relieve symptoms, it is important to avoid self-medicating without professional guidance.
If symptoms are severe, persistent, or accompanied by low energy, blood in the stool, or dehydration, veterinary care is essential. Early diagnosis and proper treatment can help your dog recover faster while preventing complications.
As a responsible pet owner, monitoring symptoms closely and consulting your veterinarian remain the safest ways to protect your dog’s digestive health and overall wellbeing. For more pet care advice, explore additional resources on canine nutrition, illness prevention, and safe medication use.
