How to Fix Your Dog's Upset Stomach at Home

Every dog has an off day. A scavenged scrap on a walk, a treat that didn't agree with them, a stressful afternoon that upset the gut-brain axis. Mild stomach upsets happen, and not every one of them needs a vet visit. The key is knowing which situations are safe to manage at home, doing it correctly, and recognising when home care has reached its limit.

Getting this wrong in either direction causes problems. Unnecessary vet visits for genuinely minor upsets are stressful and expensive. Attempting home care when something more serious is happening can delay treatment that genuinely matters.

First: Is Home Care Actually Appropriate Here?

Before reaching for the rice cooker, run through this checklist honestly.

Home management is appropriate only when all of the following are true:

• Your dog is an otherwise healthy adult
• Symptoms are mild, loose stools or a single vomiting episode
• There is no blood in the stool or vomit
• Your dog is still drinking water
• Energy levels are relatively normal, alert, moving around
• There is no abdominal bloating or visible pain

If any of these do not apply, skip home care and contact your vet. Puppies, senior dogs, pregnant dogs, and dogs with known underlying conditions like diabetes or kidney disease should never be managed at home without veterinary guidance. These dogs are far more vulnerable to rapid deterioration from dehydration and gut disruption.

Step 1: The Fasting Period

The first step in settling an upset stomach is giving the gut a complete rest from food. When the digestive system is irritated, continuing to send food through it compounds the problem. A short fast allows the gut lining to recover and the bacterial balance to begin stabilising.

For healthy adult dogs:

• Withhold food for 12 to 24 hours
• Water must remain available throughout. Never withhold water
• After 24 hours, move to the bland diet regardless of whether symptoms have fully resolved

Critical exceptions. Never fast:

• Puppies of any age
• Toy breeds prone to hypoglycaemia, including Chihuahuas, Pomeranians, and similar small dogs
• Diabetic dogs
• Pregnant or nursing dogs
• Dogs that are already visibly weak or lethargic

For these dogs, skipping meals carries its own serious risks. Hypoglycaemia can develop quickly in small breeds and puppies, and diabetic dogs need food to be timed with their medication. When in doubt, call your vet before fasting.

Step 2: The Bland Diet

Once the fasting period is over, or sooner if your dog is a small breed that needs food, introduce a bland diet in small, frequent portions. The goal is to give the gut something easy to process while the microbiome restabilises.

The standard veterinary recommendation:

• Boiled chicken, skinless and boneless, combined with plain white rice
• Ratio of one part chicken to two parts rice
• No salt, no oil, no spices, no seasoning of any kind
• Feed small portions every few hours rather than one or two larger meals

The reasoning behind small and frequent is important. Large meals put significant demand on a recovering gut. Smaller portions spread through the day keep something in the stomach without overwhelming the digestive system, which also reduces the risk of bile vomiting from an empty stomach.

How long to stay on the bland diet:

Most dogs with mild upsets respond well within 2 to 3 days. Once stools have been normal for a full day, begin transitioning back to the regular diet gradually. Mix roughly 25% regular food with 75% bland diet, then shift the ratio over 3 to 4 days. Jumping straight back to normal food after a gut upset is one of the most common ways pet parents accidentally trigger a second round of loose stools.

Step 3: Hydration Is Not Optional

Vomiting and diarrhea both cause fluid loss, and dehydration sets in faster than most people expect. A dog that is not drinking adequately during a gut upset is heading toward a situation that home care cannot handle.

Keep your dog drinking by offering:

• Fresh, clean water replenished frequently throughout the day
• Small ice cubes for dogs that are reluctant to drink but will take ice
• Plain, diluted chicken broth with no onion, no garlic, and no added salt, offered in small amounts alongside water
• Oral rehydration support if recommended by your vet

Check for dehydration at home by gently pinching the skin over the shoulder blades and releasing. It should snap back immediately. A slow return signals dehydration. Check the gums too. They should be moist and pink. Dry, tacky, or pale gums alongside a gut upset mean you need veterinary care, not more rice.

Step 4: Create a Calm Environment

This step gets skipped more than it should. The gut and brain communicate directly through the gut-brain axis, and stress actively disrupts gut motility and the microbiome. A dog that is anxious, overstimulated, or unsettled will recover more slowly from a gut upset than one that is calm and resting.

During home management:

• Keep the environment quiet and predictable
• Avoid long or strenuous walks. Short, calm toilet trips only
• Minimise exposure to stressors like loud noises, other animals, or unfamiliar visitors
• Let your dog rest as much as they want to

When to Stop Home Care and Call Your Vet

Home management has a time limit. If any of the following appear, stop home care and contact your vet:

• No improvement after 24 to 48 hours
• Symptoms are getting worse rather than better
• Blood appears in the stool or vomit at any point
• Vomiting and diarrhea are both present together
• Your dog stops drinking water
• Lethargy increases or your dog becomes visibly unwell
• Abdomen appears bloated or your dog shows signs of pain

These are not signs to monitor for another day. They are signs that whatever is happening is beyond what home care can address.
