What to Do If Your Dog Has an Upset Stomach
Expert tips on spotting symptoms, home remedies, and when to call the vet for your dog's tummy troubles.

Dogs often experience upset stomachs due to dietary indiscretions, stress, or infections, but prompt action can lead to quick recovery. Common remedies include fasting, hydration, and bland diets, while severe cases require veterinary intervention.
Symptoms of an Upset Stomach in Dogs
Recognizing the signs early helps prevent complications. Key symptoms include:
- Vomiting and diarrhea, the most frequent indicators
- Lip smacking or excessive licking
- Excessive stomach noises, belching, or gas
- Eating grass or gulping repeatedly
- Lethargy, weakness, or loss of appetite
- Abdominal pain, shown by whining when touched or stretched posture
- Fever or straining to defecate
These symptoms typically resolve in 24-48 hours with care, but monitor closely.
Common Causes of Upset Stomach in Dogs
Several factors trigger gastrointestinal distress in dogs:
- Dietary indiscretion: Eating garbage, spoiled food, or table scraps
- Food allergies or sensitivities: Reactions to ingredients like grains or proteins
- Infections: Bacterial, viral (e.g., parvovirus), or parasitic
- Stress or anxiety: Changes in routine or environment
- Foreign objects: Swallowed toys or bones causing blockages
- Toxins: Ingestion of chemicals or plants
- Underlying conditions: Pancreatitis, ulcers, or cancer
Identifying the cause guides treatment; for instance, parvovirus demands isolation and fluids.
Home Remedies for Dog Upset Stomach
For mild cases, try these vet-recommended strategies before seeking professional help.
1. Keep Your Dog Hydrated
Dehydration worsens symptoms, so encourage water intake. Add honey to water (1 tbsp per cup, cooled) for appeal, or offer bone broth rich in nutrients and soothing for the GI tract. Ice cubes or diluted electrolytes also help.
2. Fast Your Dog
Withhold food for 12-24 hours (puppies 12 hours max) to rest the gut, providing water throughout. This allows the digestive system to reset.
3. Bland Diet Transition
After fasting, introduce small meals of boiled chicken and white rice (1:2 ratio), plain pumpkin, or sweet potatoes. Low-fat cottage cheese works too. Feed 3-6 small meals daily, gradually returning to normal diet over 3-5 days.
| Food Option | Ratio/Portion | Benefits |
|---|---|---|
| Boiled Chicken & Rice | 1:2 (chicken:rice) | Easily digestible, binding for diarrhea |
| Plain Pumpkin | 1-4 tbsp per meal | Fiber aids digestion |
| Boiled White Fish | Plain, skinless | Gut-friendly protein |
4. Probiotics and Fiber
Probiotics restore gut bacteria; plain yogurt or vet-recommended supplements help. Fiber-rich foods like pumpkin support regularity.
5. Herbs and Natural Aids
Ginger or chamomile tea (cooled, diluted) can soothe nausea; consult a vet first.
Avoid human meds without guidance; over-the-counter options like famotidine may help acid issues but require dosing approval.
When to See a Vet for Dog Stomach Issues
Seek immediate care if symptoms persist beyond 48 hours or include:
- Bloody vomit/diarrhea
- Severe lethargy or dehydration (dry gums, sunken eyes)
- Bloating or unproductive retching
- Fever over 102.5°F
- Repeated vomiting post-fasting
- Puppy, senior, or chronic illness
Vets may provide IV fluids, anti-nausea drugs (e.g., Cerenia), antibiotics, or diagnostics like X-rays.
Veterinary Treatments for Severe Cases
Professional interventions include:
- IV fluids and hospitalization for dehydration
- Anti-emetics like maropitant (Cerenia) or ondansetron
- Antacids (famotidine, omeprazole) for ulcers
- Antibiotics or dewormers for infections
- Surgery for obstructions or parvovirus complications
- Hydrolyzed diets for allergies
For parvovirus, monoclonal antibodies shorten recovery.
Preventing Upset Stomach in Dogs
Proactive steps reduce recurrence:
- Feed high-quality, consistent diet; avoid scraps
- Gradual food transitions over 7-10 days
- Regular deworming and vaccinations
- Secure trash and toxic items
- Exercise and stress reduction
- Probiotic supplements routinely
