Gurgling tummy. Soft poos. Enough wind to clear the lounge.
If your dog seems perfectly happy one day and develops an upset stomach the next, it can be incredibly frustrating trying to work out what's going on.
Some dogs genuinely seem to have more delicate digestive systems than others.
But here's the important bit:
“Sensitive stomach” isn't really a diagnosis.
Loose stools, vomiting, excessive wind or digestive discomfort can happen for all sorts of reasons—from eating something questionable at the park to parasites, illness, sudden food changes or an ingredient that simply doesn't agree with your dog.
So before changing their food for the fifth time this month, let's look at what may be happening and how to make their diet a little easier to investigate.
Every dog is different, but signs that owners commonly associate with a sensitive tummy include:
One random soft poo doesn't necessarily mean your dog has a food sensitivity.
Dogs are rather talented at eating things they shouldn't.
It's recurring patterns that are worth paying attention to.
Food is only one possibility.
Digestive upset can be associated with things such as:
That's why recurring diarrhoea or vomiting shouldn't simply be labelled a “sensitive stomach” forever without considering whether something else needs investigating.
Possibly.
But changing foods randomly makes it surprisingly difficult to find out.
Sometimes the issue isn't the overall type of food at all.
It may be:
A useful first step is therefore simplifying things rather than adding more things.
If your dog's diet includes chicken kibble, beef roll, three different treats, cheese from the fridge, dental chews and whatever the kids slip under the table, identifying the culprit becomes rather difficult.
There isn't one universally “best” food for every dog with a sensitive stomach.
Instead, there are several things worth thinking about.
When you're trying to work out what your dog tolerates, knowing exactly what they're eating helps enormously.
A food with clearly named animal proteins makes it much easier to track what agrees with your dog than continually feeding meals containing numerous unidentified or mixed protein sources.
Simple doesn't automatically mean better nutritionally—but it can make troubleshooting much easier.
Some dogs digest everyday proteins such as chicken or beef beautifully.
Others don't seem to get on with them at all.
If you suspect a particular protein isn't suiting your dog, repeatedly moving between products that all contain the same protein won't necessarily help.
This is one reason some owners investigate single or novel proteins.
A novel protein is simply a protein your individual dog has eaten rarely—or never—before.
Examples may include:
Our Novel Proteins for Dogs NZ Guide explains this in more detail.
But remember: novel doesn't automatically mean hypoallergenic or easier to digest.
It simply gives you another protein option.
Fat is an important part of a dog's diet, but more isn't always better for every dog.
Some dogs tolerate rich, fatty foods perfectly well.
Others develop digestive upset when meals suddenly become much richer.
And dogs with certain medical conditions—including some dogs with pancreatitis or chronic gastrointestinal disease—may require carefully controlled dietary fat under veterinary guidance.
So if your dog consistently reacts after particularly rich meals, it's worth looking at the entire nutritional picture rather than just changing proteins.
Dogs with sensitive digestive systems often benefit from one very unexciting ingredient:
consistency.
Constantly swapping foods, proteins, treats and toppers can make it difficult for both your dog's digestive system and you.
If you're introducing something new, change one thing at a time.
That way, if things improve—or go spectacularly in the opposite direction—you have a much better idea why.
This is particularly important when feeding raw.
A single packet of lean meat isn't automatically a complete diet.
For example, boneless horse or kangaroo meat can be useful ingredients within a raw feeding programme, but meat alone doesn't provide everything a dog requires long term.
Growing puppies, pregnant or lactating dogs and dogs with medical conditions require particular care.
If you're building your dog's meals yourself, start with our Raw Dog Feeding Guide NZ and seek appropriate nutritional or veterinary advice where needed.
It can be appropriate for some dogs.
The useful thing about feeding simple raw ingredients is that you can have much greater visibility over exactly which animal proteins you're feeding.
That makes it easier to create a controlled diet rather than guessing what is hidden within a complicated ingredient list.
But raw feeding isn't automatically the right solution to every digestive problem.
If your dog has ongoing vomiting, chronic diarrhoea, unexplained weight loss, pancreatitis, inflammatory bowel disease or another gastrointestinal condition, speak with your veterinarian before making major dietary changes.
Sometimes a veterinary therapeutic diet is the most appropriate option.
The goal shouldn't be to prove that one style of feeding is best.
It should be to find what works safely for your individual dog.
If your dog already eats raw food and you're looking to simplify their protein choices, a single or clearly identified animal protein can make the process easier to monitor.
Here are a few examples from our range.
Our Wild Goat Raw Dog Food contains wild New Zealand goat in an 80:10:10 meat, bone and organ blend.
Goat is less commonly fed than chicken, beef or lamb and is naturally lean, giving raw feeders another clearly identified protein option.
Our Kangaroo Dog Food NZ is boneless kangaroo meat and is an exceptionally lean, uncommon protein for many Kiwi dogs.
Because it is boneless meat, however, it needs to form part of an appropriately balanced diet rather than being fed alone long term.
Horse Meat for Dogs is another uncommon protein and is supplied as boneless horse meat.
It's a useful option when you want greater control over the animal protein you're introducing, but again needs to be balanced appropriately if fed as part of a long-term raw diet.
Depending on what your dog has eaten previously, you may also consider proteins such as possum, venison, hare or rabbit.
The important question isn't:
“Which protein is best for sensitive dogs?”
It's:
“Which proteins does my individual dog tolerate well?”
Tripe is popular with raw feeders and many dogs absolutely love it.
Our Minced Lamb Tripe is a simple raw ingredient that can be incorporated into an appropriately balanced raw feeding programme.
But we wouldn't suggest treating tripe as a cure for vomiting or diarrhoea.
If your dog is already experiencing gastrointestinal upset, the priority is identifying why rather than simply adding more foods to the bowl.
Sometimes less is more when you're troubleshooting digestion.
Bone broth can be a handy way of adding moisture and flavour to meals.
For dogs that enjoy it, a small amount poured over food can make meals more appealing and increase moisture intake.
You can explore our Bone Broth & Milk range.
Again, though, bone broth isn't a treatment for persistent gastrointestinal disease.
Think of it as a food or topper—not a substitute for veterinary investigation.
Not automatically.
“Grain-free” and “sensitive stomach” aren't the same thing.
Some dogs may have problems with particular ingredients, but many dogs digest grains perfectly well.
Likewise, removing grains while continuing to feed the ingredient your dog actually reacts to won't solve very much.
Instead of assuming one entire food group is the problem, look at:
The aim is to identify your dog's actual trigger, if there is one.
They're not necessarily the same thing.
Food allergies can cause gastrointestinal signs such as vomiting, diarrhoea, soft stools or excess wind, but they can also cause skin symptoms.
If your dog has digestive problems alongside:
food allergy may be one possibility worth discussing with your veterinarian.
We've covered this separately in our Itchy Dog NZ Guide.
If a true food allergy is suspected, a properly controlled elimination diet is much more useful than simply jumping between different foods.
This catches people out all the time.
You've carefully chosen one protein for dinner...
...and then someone gives the dog a chicken treat.
Or a beef dental chew.
Or half a sausage.
If you're genuinely trying to work out whether a particular food or protein is causing problems, everything that goes into the dog's mouth matters.
That can include:
You don't necessarily have to remove all of these forever.
You simply need to account for them when investigating a pattern.
Unless your veterinarian has given you different instructions, suddenly changing a dog's entire diet can itself cause digestive upset.
A gradual transition lets you observe how your dog responds.
For dogs moving onto raw food, don't feel pressured to introduce every available protein immediately.
Start simply.
Introduce the diet thoughtfully, monitor stool quality and appetite, and add variety over time once you're confident your dog is coping well.
Our Raw Dog Feeding Guide NZ covers transitioning and feeding quantities in more detail.
This sounds slightly obsessive.
It's also incredibly useful.
For a couple of weeks, write down:
What your dog ate
Include meals, treats, chews and scraps.
Protein sources
Chicken? Beef? Goat? A mixture?
Stool quality
Normal, soft or diarrhoea.
Vomiting or regurgitation
Note when it happened in relation to food.
Wind and tummy noises
Skin or ear symptoms
Any medication or supplements
Anything unusual
A raid on the rubbish bin deserves an honourable mention.
Patterns that seem impossible to spot from memory can become surprisingly obvious when they're written down.
Occasional mild digestive upset can happen.
But veterinary advice is important if your dog has:
Be particularly cautious with puppies, elderly dogs and dogs with existing medical conditions because they can become unwell or dehydrated more quickly.
And if you're simply thinking, “This isn't normal for my dog,” getting veterinary advice is never a bad call.
There isn't one food that wins for every dog.
For one dog it might be a straightforward everyday protein they've eaten happily for years.
Another may do better on a leaner diet.
Another may need a genuinely novel protein.
And another may need a veterinary therapeutic diet rather than something selected from a pet-food shelf.
The useful principles are remarkably simple:
Know what you're feeding.
Change one thing at a time.
Introduce new foods gradually.
Don't assume grain, chicken, fat or any other ingredient is automatically the villain.
Watch the individual dog in front of you.
That's far more useful than chasing the latest miracle ingredient.
At The Raw Dog Food Co, one of the things we specialise in is giving Kiwi raw feeders plenty of choice.
Alongside everyday favourites, we stock less commonly fed proteins including New Zealand wild goat, possum, venison and hare, plus kangaroo, horse, rabbit and more.
That makes it easier to build variety into a raw diet—or keep things intentionally simple when you want to know exactly what your dog is eating.

Common signs include recurring soft stools, diarrhoea, excess wind, stomach noises, occasional vomiting and difficulty coping with changes in food. However, these symptoms can also be caused by medical conditions, parasites or other problems, so persistent symptoms should be investigated by a veterinarian.
There is no single best food for every dog. The ideal diet depends on the cause of the digestive problem. Some dogs may benefit from a simple diet with clearly identified ingredients, an appropriate fat level or a different protein source, while others may require a veterinary therapeutic diet.
Some dogs with sensitive stomachs eat raw diets successfully. Clearly identified raw ingredients can make it easier to know which proteins are being fed. However, raw food isn't automatically suitable for every digestive condition, and persistent gastrointestinal problems should be discussed with your veterinarian.
There isn't one universally best protein. The right choice depends on the individual dog and what they tolerate. Less commonly fed proteins such as goat, kangaroo, horse, venison, possum or hare can provide alternatives to conventional proteins, but being novel doesn't guarantee that a protein will suit every dog.
Kangaroo is very lean and is an uncommon protein for many dogs, which makes it an option some owners consider when simplifying their dog's diet or moving away from commonly fed proteins. It isn't automatically suitable for every dog and boneless kangaroo needs to be appropriately balanced if fed as part of a long-term raw diet.
Goat is naturally lean and less commonly used in mainstream dog foods than chicken, beef or lamb. This makes it another protein option for owners wanting something different, although every dog's tolerance is individual.
Some dogs don't tolerate particularly rich or high-fat meals well. Certain medical conditions also require careful dietary fat management. If your dog repeatedly becomes unwell after fatty foods, discuss it with your veterinarian rather than simply experimenting with different foods.
Not necessarily. Some individual dogs may react to particular ingredients, but grains aren't automatically responsible for digestive problems. Protein sources, fat, food quantity, rapid dietary changes and underlying medical conditions should also be considered.
For many dogs, introducing a new food gradually is preferable to an abrupt change, particularly if they already have a sensitive digestive system. The exact transition can depend on your dog and the reason for changing diets, so follow veterinary advice where a medical condition is involved.
Repeated vomiting, persistent diarrhoea, blood, abdominal pain, lethargy, dehydration, weight loss or refusal to eat or drink should prompt veterinary advice. Puppies, elderly dogs and dogs with existing health conditions may need attention sooner.
A sensitive stomach can turn feeding your dog into quite the detective exercise.
But throwing every “gut health” product you can find into the bowl usually makes the investigation harder—not easier.
Keep things simple.
Pay attention to patterns.
Know which proteins you're feeding.
Make dietary changes carefully.
And when digestive problems persist, involve your veterinarian rather than assuming food is the only possible cause.
Sometimes the best diet isn't the trendiest one.
It's simply the one that keeps your individual dog happy, healthy and producing reassuringly boring poos.
