What to Feed Dog With Upset Stomach: Vet-Approved Guide & Tips

So your pup's got an upset stomach? Been there. Last month my Labrador Max got into the trash and spent two days with diarrhea and vomiting. You're probably panicking right now wondering what to feed dog with upset stomach. Relax - most cases aren't emergencies. But getting their diet wrong can make things worse.

Spotting the Signs: Is It Really an Upset Stomach?

Not every tummy rumble means trouble. Real digestive upset usually shows these symptoms:

  • Gurgling belly sounds you can hear across the room
  • Refusing meals (even treats)
  • Excessive burping or gas
  • Vomiting bile (that yellow foamy stuff)
  • Diarrhea ranging from soft serve to watery
  • That "guilty" posture - hunched back, sad eyes

When to skip home treatment: If you see blood in vomit/diarrhea, pale gums, or your dog can't keep water down - vet immediately. My neighbor waited too long with her Beagle and needed IV fluids.

Why Do Dogs Get Upset Stomachs Anyway?

From my experience volunteering at the shelter, these are the top culprits:

CauseHow It HappensPrevention Tip
Dietary indiscretionEating garbage/roadkill (Max's specialty)Use locking trash cans
Sudden food changesSwitching kibble brands overnightTransition over 7-10 days
Food allergiesChicken/beef sensitivityElimination diet trials
ParasitesGiardia from pond waterRegular fecal tests
StressThunderstorms or new petsAdaptil diffusers

Honestly? Half the "mystery" stomach issues I've seen trace back to owners feeding table scraps. Bacon grease might seem like love, but your dog's pancreas disagrees.

The Step-by-Step Feeding Protocol

Phase 1: The Fasting Period

When symptoms first hit:

  • Adult dogs: Skip 12-24 hours of food (but NOT water)
  • Puppies/seniors: Max 12 hours fasting - they can't handle it
  • Offer ice cubes if they're vomiting - prevents dehydration without overwhelming the stomach

I learned this the hard way - feeding too soon just restarts the vomiting cycle. Gut rest is crucial.

Phase 2: Reintroducing Foods

Now the big question: what to feed dog with upset stomach after fasting? Follow this progression:

DayMealsServing SizeNotes
13-4 small meals1-2 tbsp per 10lbs body weightBland foods only
2-33 mealsIncrease by 25% dailyMaintain bland diet
4+Transition backNormal portionsMix bland + regular food

The Bland Diet Formula

For homemade meals when figuring out what to feed a dog with upset stomach:

  • Base (75%): Boiled white rice OR peeled boiled potatoes
  • Protein (25%): Lean ground turkey OR chicken breast OR low-fat cottage cheese
  • Optional: 100% pumpkin puree (not pie filling!) - 1 tsp per 10lbs

Cook everything plain - no salt, butter, or oils. My vet suggested adding slippery elm powder during Max's recovery - worked wonders.

Pro tip: Bake the mixture into small meatballs. Easier to portion control than messy mush.

Commercial Foods That Actually Work

Not everyone can cook homemade. These vet-recommended options saved me during work trips:

BrandProductWhy It WorksCost Per Serving
Hill'sPrescription Diet i/dPrebiotics + highly digestible$2.50-$3
PurinaPro Plan EN GastroentericElectrolyte balanced$2-$2.75
Royal CaninGI Low FatReduced fat content$3-$3.50

Big caveat: Some over-the-counter "sensitive stomach" foods still contain common allergens like chicken. Always check labels.

What NOT to Feed During Recovery

Some "remedies" do more harm than good:

  • Pepto-Bismol: Contains aspirin derivatives toxic to dogs
  • Milk/bread: Can worsen diarrhea in lactose-intolerant dogs
  • Raw eggs/meat: Salmonella risk when immune system is weak
  • High-fat treats: Pancreatitis trigger

I made the milk mistake with my first dog - turned mild diarrhea into a fountain situation.

Hydration: The Silent Priority

Diarrhea/vomiting dehydrates dogs fast. Check for:

  • Dry nose/gums
  • Skin tenting (pinch shoulder skin - slow snapback = dehydration)

Rehydration solutions:

  • Homemade electrolyte mix: 1L water + 1 tsp salt + 1 tbsp honey
  • Ice chips/licks: For vomiting dogs
  • Unflavored Pedialyte: Diluted 50/50 with water

When Normal Food Returns

Transitioning back requires patience:

Transition DayBland FoodRegular Food
1-275%25%
3-450%50%
5-625%75%
7+0%100%

If symptoms return at any stage? Go back to previous step for 2 more days. Rushing this caused Max's relapse last year.

Preventing Future Flare-ups

After surviving three dog stomach crises, my prevention kit includes:

  • Probiotics: Purina FortiFlora added to meals twice weekly
  • Pumpkin powder: Shelf-stable alternative to canned pumpkin
  • Limited ingredient treats: Single-protein sources like salmon
  • Slow feeder bowl: Stops my lab from inhaling food

The probiotic expense is worth avoiding emergency vet bills.

Your Top Questions Answered

Can I give my dog rice alone for upset stomach?

Short-term yes, but long-term no. Rice lacks protein - add lean meat by day 2 or they'll start losing muscle mass. My vet chewed me out for doing this for 5 days.

How long before I see improvement?

Vomiting should stop within 24 hours of fasting. Diarrhea improves in 2-4 days on bland diet. No improvement? Time for vet tests.

Is pumpkin necessary?

Helpful but optional. The fiber absorbs excess water in the intestines. Use plain canned pumpkin - pie mix has toxic nutmeg.

What human foods are safe for dogs with upset stomach?

Besides the bland diet formula: boiled sweet potatoes, oatmeal, plain yogurt (if dairy-tolerant). Avoid all seasoned/spiced foods.

Should I withhold water if my dog is vomiting?

Never! Offer small amounts frequently (1 tsp per lb body weight hourly). Dehydration kills faster than vomiting.

Final Thoughts from the Trenches

Figuring out what to feed dog with upset stomach is overwhelming when your best friend is sick. Stick to the bland diet protocol religiously - improvising prolongs recovery. Track everything in a symptom journal (vets love this). And invest in a good carpet cleaner - you'll need it. Remember that most stomach upsets pass within 3-5 days with proper care. But when in doubt? Skip Dr. Google and call your actual vet.

After Max's third stomach episode, I created a "doggy first aid kit" with canned pumpkin, probiotics, and prescription food. Best $75 I ever spent. Last month's garbage incident? Handled in 48 hours with zero vet visits.
