Why Does My Dog Have a Sensitive Stomach? Causes and How to Settle It

Soft or messy stools, the odd bout of vomiting, rumbling tummies and a lot of grass-eating: a sensitive stomach is one of the most common things dog owners deal with. Most cases are manageable at home once you understand what is going on. Here is how to settle a sensitive gut, and when it is time to see the vet.

Signs of a sensitive stomach

• Loose, soft or inconsistent stools
• Occasional vomiting or regurgitation
• Excess wind and a gurgling tummy
• Eating grass, then bringing it back up
• A reduced or picky appetite
• A dull coat, since gut health and coat health are linked

Common causes

The usual suspects are a sudden change of food, scavenging or table scraps, eating too fast, stress and anxiety (the gut and brain are closely connected), food sensitivities, and parasites. Puppies and older dogs tend to have more delicate digestion.

When to see the vet, not wait it out

Contact your vet promptly if you see blood in the stool or vomit, repeated vomiting, lethargy, a painful or bloated belly, signs of dehydration, or if a puppy or senior dog is affected. Ongoing or severe tummy trouble needs a proper diagnosis.

How to settle a sensitive gut

1. Transition food slowly

Never switch food overnight. Mix the new food in over 7 to 10 days, increasing the proportion gradually, to give the gut time to adjust.

2. Feed simple, and slow it down

For a mild upset, a bland diet for a day or two can help. If your dog inhales their food, a slow feeder bowl reduces the gulping of air that causes wind and discomfort.

3. Support the microbiome

A balanced gut is the foundation of good digestion. Pre and probiotics help support healthy gut bacteria, pumpkin is a gentle source of fibre for firmer stools, and slippery elm helps soothe the digestive tract. Our Gut & Glow chews bring these together in a daily chew.

4. Manage stress

Because the gut and brain talk to each other, an anxious dog often has a sensitive stomach. If your dog is prone to stress, our guide on calming an anxious dog may help the tummy too.

Frequently asked questions

Is pumpkin good for a dog's upset stomach?

Yes, plain pumpkin is a gentle, well-tolerated source of fibre that can help firm up loose stools. It is a key ingredient in our Gut & Glow chews.

Do probiotics work for dogs?

Pre and probiotics are widely used to support a balanced gut microbiome and healthy digestion. They work best given consistently over time.

How long before I see firmer stools?

With consistent daily gut support and a stable diet, many owners notice more regular, firmer stools within a couple of weeks.

Could my dog's sensitive stomach be a food allergy?

It can be. Persistent tummy trouble alongside itchy skin can point to a food sensitivity. Your vet can help you investigate with an elimination diet.

The bottom line

Most sensitive stomachs settle with slow food transitions, calmer mealtimes, a supported microbiome and less stress. Know the red flags that mean a vet visit, and support the gut daily the rest of the time. Our Gut & Glow chews are an easy place to start, backed by our 60-night promise.
