A Practical Guide to Gastrointestinal Illness in Dogs

When your dog becomes suddenly unwell with vomiting, diarrhoea, or other gastrointestinal symptoms, it can be incredibly stressful. You might feel overwhelmed, guilty, or unsure whether to rush to the vet. This guide is here to help you stay calm, informed, and prepared, even when emotions are high. From what questions to ask your vet to what to pack in an emergency bag, we’ve got you covered.

1. What are the signs of a gastrointestinal issue in dogs?

Look out for:

• Vomiting

• Diarrhoea

• Drooling or lip-smacking (nausea)

• Gurgling stomach

• Loss of appetite

• Lethargy

• Signs of abdominal discomfort (whining, restlessness, hunching)

These symptoms can range from mild to serious. Trust your instincts—if your dog seems ‘off’, you’re not overreacting.

2. When should I call the vet?

Call your vet if:

• Vomiting or diarrhoea lasts more than 24 hours

• There’s blood in vomit or stool

• Your dog seems in pain, unusually tired, or won’t eat

• They are very young, very old, or have other health conditions

• You suspect they’ve eaten something toxic

Never feel like you’re wasting your vet’s time. Prompt action can prevent things getting worse.

3. I’m too emotional to speak properly at the vet—what can I do?

It’s completely normal to feel upset when your dog is unwell. To help, here’s a script you can read or hand over at the clinic:

💬  Vet Visit Script for When You’re Too Upset to Talk

“Hi, I’m really worried about my dog and feeling too emotional to speak clearly. Here’s what’s been going on:

• Name: [Dog’s Name]

• Age: [Age]

• Breed: [Breed]

• Symptoms: Vomiting / Diarrhoea / Loss of appetite / Lethargy (tick as appropriate)

• Duration: [e.g. 12 hours / 2 days]

• Recent changes: [New food? Got into the bin? Ate something outdoors?]

• Medication or existing conditions: [e.g. on flea tablets / has pancreatitis]

Please let me know what tests or treatments you recommend and any costs involved before going ahead. I really appreciate your help.”

4. What should I bring to the vet?

Prepare a simple Canine Medical Bag to grab when things go wrong:

👜 Emergency Vet Visit Checklist

• Your dog’s medical history (vaccinations, meds, allergies)

• A recent photo (in case of emergency handover)

• A notebook and pen (or phone notes)

• Poo sample (fresh, in a sealed container or poo bag)

• Vomit photo (gross but helpful!)

• Insurance details

• Lead and harness

• Comfort item (blanket or toy)

5. What questions should I ask the vet about tummy upsets?

Here’s a list you can print or screenshot:

❓ Essential Questions to Ask

• Do you think this is an infection, dietary issue, or something more serious?

• Will you need blood tests or imaging?

• Could this be pancreatitis, a blockage, or poisoning?

• Should I feed them today, and what food is best?

• Do they need fluids or hospitalisation?

• Can I take them home today?

• What signs should I watch for that would need an emergency return?

6. What should I feed my dog after a stomach upset?

After GI illness, dogs need gentle, easy-to-digest food. Once your vet gives the go-ahead, many recommend:

• Boiled white rice and plain cooked chicken or turkey (no skin or bones)

• Or lightly steamed white fish with sweet potato

When your dog is ready to return to their usual meals, choose food made with high-quality, natural ingredients and no artificial additives. At Poppy’s Picnic, we offer fresh raw food that’s easy on sensitive stomachs. Try:

• Poppy’s Picnic Chicken Mince for Dogs

• Poppy’s Picnic Turkey Mince for Dogs

These recipes are free from fillers and made from fresh meat and vegetables, ideal for a gentle transition back to regular feeding.

7. How can I prevent future stomach upsets?

Here are some smart strategies:

• Stick to a consistent, high-quality diet

• Avoid rich treats or too many table scraps

• Keep rubbish bins secure and off-limits

• Supervise outdoor play—especially in parks or beaches

• Worm your dog regularly

• Introduce new foods slowly (including chews or supplements)

8. Is it my fault my dog got ill?

No. Dogs are curious, often indiscriminate eaters, and even the best owners can’t control everything. What matters most is acting quickly and compassionately—exactly what you’re doing now.

9. What are common causes of upset stomachs in dogs?

Some typical culprits:

• Eating something they shouldn’t (bin raids, garden debris)

• Food intolerance or allergy

• Sudden food change

• Infections (bacterial, viral, or parasitic)

• Stress or anxiety

• Underlying conditions like pancreatitis or IBD

10. What can I keep at home for minor upsets?

Here’s a handy list of things to have in your pet’s medicine cupboard:

🏥 At-Home GI Kit

• Bland food ingredients (chicken, rice, sweet potato)

• Electrolyte powder for pets (e.g. Oralade)

• Dog-safe probiotic paste (e.g. Pro-Kolin or VetPro Digestive)

• Thermometer (know how to use it safely)

• Vet’s emergency number

• Access to your dog’s insurance policy

Always speak to your vet before giving any over-the-counter products.

Final Words of Reassurance

You’re not alone. GI issues are one of the most common reasons for emergency vet visits, and most dogs bounce back quickly with the right care. The key is preparation, observation, and not being afraid to ask for help—whether that’s from your vet, a friend, or even this guide.

If your dog is recovering now, that’s brilliant. If you’re still in the thick of it, take a breath. You’re doing everything right.
