🛑 Portugal Dog Danger Checklist
Heat • Parasites • Caterpillars • Your First Vet Visit
A quick safety guide for people moving to Portugal with a dog
🔥 HEAT SAFETY
The biggest immediate risk for newly arrived dogs
Portugal’s heat, sun intensity, and pavement temperatures are often underestimated, especially by people coming from northern Europe.
❌ Common Mistakes
-
Walking dogs at midday or early afternoon
-
Assuming shade makes hot pavement safe
-
Not adjusting routines during heatwaves
-
Feeding or exercising at the hottest times
✅ Heat Safety Checklist
☐ Walk dogs early morning or late evening only
☐ Test pavement with your hand (if you can’t hold it for 5 seconds, it’s too hot)
☐ Always carry water on walks
☐ Provide shade and airflow at home
☐ Adjust feeding times in summer
☐ Never leave a dog in a parked car, even briefly
🚨 Heatstroke Warning Signs
-
Heavy or uncontrolled panting
-
Excessive drooling or thick saliva
-
Weakness, confusion, or collapse
-
Vomiting or diarrhoea
If you see these signs: Cool the dog gradually (not ice-cold water) and go to a vet immediately.
🦟 PARASITES
A year-round issue, not a seasonal one
Many parasites remain active throughout the year.
Parasites Commonly Seen
-
Ticks
-
Fleas (including indoors)
-
Mosquitoes (heartworm risk)
✅ Parasite Protection Checklist
☐ Use flea & tick prevention year-round
☐ Ask your vet about heartworm prevention
☐ Check your dog after walks, especially in green or rural areas
☐ Wash dog bedding regularly
☐ Ask your vet what parasites are common where you live
⚠️ Important: Local vets often assume parasite prevention is already in place.
🐛 PROCESSIONARY CATERPILLARS
A serious and often unknown danger
Certain caterpillars found in Portugal are highly dangerous to dogs. Contact can cause severe injury or death.
Why They’re Dangerous
-
Covered in toxic hairs
-
Dogs may sniff, lick, or bite them
-
Contact can cause tissue damage to the mouth and tongue
When They Appear
-
Mainly late winter to spring
-
Often near pine trees
-
Seen on the ground, sometimes moving in a line
🚨 Symptoms After Contact
-
Sudden drooling or foaming
-
Swollen tongue or mouth
-
Pain, pawing at the face
-
Vomiting or distress
❗ What To Do
-
Do NOT touch the mouth or tongue
-
Rinse with water only if advised by a vet
-
Go to an emergency vet immediately
☐ Avoid pine forests during caterpillar season
☐ Keep dogs on lead in affected areas
☐ If in doubt — assume it’s dangerous
🏥 YOUR FIRST VET VISIT
Strongly recommended within the first 1–2 weeks
An early vet visit helps your dog adapt safely to the local climate and health risks.
When to Go
-
Within 1–2 weeks of arrival
-
Immediately if parasite prevention is not active
-
Immediately if your dog shows signs of illness, heat stress, or caterpillar contact
Bring With You
☐ EU pet passport
☐ Vaccination records
☐ Microchip information
☐ List of current food and medications
What the Vet Will Likely Ask

Where you moved from
-
Whether you live in an urban or rural area
-
Your dog’s size, age, and activity level
-
What prevention you are currently using
Costs (General Guidance)
-
Vet consultations are often more affordable than in the UK or US
-
Preventative treatments are widely available
✅ QUICK PEACE-OF-MIND SUMMARY
✔ Heat is the most immediate danger
✔ Parasites require year-round prevention
✔ Caterpillars are an emergency risk
✔ An early vet visit prevents serious problems
📌 Helpful Tip
Moving countries, climate changes, and environmental stress can affect digestion. Many dogs benefit from gentle, easily digestible food during the adjustment period.
