The complete guide to treats for sensitive dogs: Simple, gentle choices for tummies, skin and fussy eaters
Some dogs can eat almost anything. Others seem to react to everything – a rumbling tummy after a new chew, a bit of scratching after a different biscuit, or a polite "no thank you" to anything unfamiliar. If that sounds like your dog, choosing treats can feel like guesswork. This guide brings everything together in one place: what to look for in treats for sensitive dogs, how single and novel proteins work, how to introduce something new calmly, and which of our step-by-step guides to read next.

If your dog has a health condition, is on medication or you're worried about a change in them, please speak to your vet first.
At a glance:
Simple is best: Treats with one protein and a short ingredients list make it easy to see what suits your dog.
Try something new to them: Many owners of sensitive dogs prefer novel proteins, like rabbit, venison or wild boar, that their dog hasn't eaten much before.
Go slowly: Introduce one new treat at a time, in tiny amounts, and give it a week before trying anything else.
Keep notes: A quick treat diary helps you – and your vet – spot what agrees with your dog and what doesn't.

What does "sensitive" mean in dogs?
"Sensitive" isn't a diagnosis. It's a word owners use when their dog seems to react more than most. It usually means one or more of these:
A sensitive tummy
Loose or soft poo, lots of wind, a gurgling tummy or the odd bout of sickness after certain foods or treats.
Sensitive skin and coat
A dull coat, a bit more scratching or licking than usual, or skin that seems easily irritated.
A fussy eater
A dog who's choosy about what they'll eat, or who turns their nose up at food but happily accepts treats.
An older or younger dog
Senior dogs and young puppies can be more delicate, and often need softer, smaller or simpler rewards.
Lots of everyday things can play a part, including sudden changes in food, too many treats, scavenging on walks, stress and rich human food. Sometimes there's a medical reason too, so always check with your vet if you notice ongoing sickness, diarrhoea, weight loss, a lot of scratching, or anything that worries you.
What to look for in treats for sensitive dogs
When you're choosing treats for a sensitive dog, the back of the packet matters far more than the front. Here's a simple checklist.
One protein
Treats made from a single meat or fish mean you're only adding one thing. If chicken suits your dog, a 100% chicken treat keeps things simple. Browse our single ingredient treats to see what this looks like.
A short, clear ingredients list
If you can recognise every ingredient, it's much easier to know what your dog is eating and spot anything that doesn't suit them.
A named meat or fish first
"Duck" or "salmon" tells you exactly what's inside. Vague phrases like "meat and animal derivatives" don't.
Grain-free or gluten-free (if grains don't suit your dog)
Not every dog needs to avoid grains, but some owners find their dogs do better without them. Grain-free treats give you one less thing to think about.
Lower fat options
Rich, fatty treats don't suit every tummy. If your dog seems to struggle with richer foods, treats from our low fat collection may sit better.
Small, easy pieces
Small treats, or soft strips you can tear, let you reward your dog without giving a lot of food in one go.
Single-protein, novel-protein and hypoallergenic treats explained
These three terms are often used together, but they mean slightly different things.
Single-protein treats
These contain just one animal protein, such as chicken, duck or salmon. They're about keeping the ingredients list short and clear.
Novel-protein treats
A novel protein is simply one your dog hasn't eaten much before. For most UK dogs, that means meats like rabbit, venison, wild boar or pheasant rather than everyday chicken or beef. Many owners of sensitive dogs prefer them for that reason. You'll find them in our novel protein treats.
"Hypoallergenic" treats
You'll see this word on lots of packets. There's no single agreed definition, so always read the ingredients list rather than relying on the label. At Mr Barnaby's, our hypoallergenic treats are made with single or novel proteins and simple ingredients, which many owners of sensitive dogs prefer.
Which should you choose?
For most sensitive dogs, the simplest place to start is a treat that's both single-protein and made with a protein your dog already does well on. If the usual proteins don't seem to agree, try a novel protein next. If your vet has your dog on a special diet or food trial, always ask them before giving any treats.
Ingredients to be careful with
Every dog is different, but these are worth a closer look:
- Mixed or unnamed meats – it's hard to know what's actually in there.
- Lots of added sugars, flavourings and colours – extras your dog doesn't need.
- Very rich, fatty chews – some dogs find these hard going.
- Dairy-heavy treats – some dogs don't do well with lots of dairy.
- Rich human food and leftovers – a common cause of tummy trouble.
Some foods are poisonous to dogs, including chocolate, grapes, raisins, onions and xylitol (a sweetener found in some foods). Contact your vet straight away if your dog has eaten any of these.
How to introduce a new treat to a sensitive dog
Going slowly is the single most helpful thing you can do. The PDSA advises avoiding sudden changes to your dog's diet, as they can cause tummy upsets or refusal to eat.
Step 1: One new treat at a time
If you introduce two new things at once, you won't know which one caused a problem. Keep everything else the same.
Step 2: Start tiny
On day one, offer a single small piece – about the size of a pea.
Step 3: Watch and wait
Keep an eye on your dog's poo, appetite, energy and skin over the next day or two.
Step 4: Build up slowly
If all is well, offer a little more over the next few days, still keeping portions small.
Step 5: Give it a week
Wait about a week before introducing anything else new. If you notice a change you're not happy with, stop the new treat and go back to what you know suits your dog.

Keeping a simple treat diary
A treat diary sounds like a lot of effort, but a few lines a day on your phone is plenty. Note down:
- What your dog had – meals, treats and any extras
- How much – roughly
- What you noticed – poo, wind, scratching, appetite, energy
- Anything else – a new walk route, a stressful day, a change at home
After a couple of weeks, patterns often jump out. A diary is also really useful to take along to your vet if you're worried.

Are air-dried treats good for sensitive dogs?

FAQs:
Q1: What are the best treats for sensitive dogs?
Simple treats with one protein and a short ingredients list are a good place to start. Many owners of sensitive dogs choose air-dried, single-meat or fish treats, and try a novel protein like rabbit or venison if the usual proteins don't agree.
Q2: What is a novel protein dog treat?
A novel protein is one your dog hasn't eaten much before, such as rabbit, venison, wild boar or pheasant. Many owners of sensitive dogs prefer them because they're different from the everyday proteins in most foods.
Q3: Are hypoallergenic dog treats worth it?
"Hypoallergenic" has no single agreed meaning, so it's the ingredients that matter. Look for treats made with single or novel proteins and a short, clear ingredients list, which many owners of sensitive dogs prefer.
Q4: How should I introduce a new treat to a sensitive dog?
Introduce one new treat at a time, starting with a single small piece. Watch your dog for a day or two, build up slowly if all is well, and wait about a week before trying anything else new.

Not every dog needs to avoid grains, but some owners find their dogs do better without them. If you're not sure, your vet can help you decide what suits your dog.
Q6: How many treats can a sensitive dog have?
The PDSA recommends that treats make up no more than 10% of your dog's daily food allowance. For sensitive dogs, keeping treats small and simple is especially helpful.
Q7: Can I give treats during a food trial?
Only with your vet's agreement. Treats can affect a food trial, so ask your vet which treats, if any, are suitable.
Q8: When should I see a vet about my sensitive dog?
Speak to your vet if your dog has ongoing sickness or diarrhoea, blood in their poo, weight loss, lots of scratching, or if they seem unwell or you're worried about a change in them.
