Wildlife & outdoor hazards

Prepare for the walk, recognise concerns and know when to call a vet. Choose a country, then a broad region and hazard.

Uses your browser location only after you click and grant permission. Coordinates stay in this page’s memory for the calculation; we do not save or send them to our servers or analytics. Your browser or operating system may use its own location provider. You can always choose manually.

Broad regions are planning aids, not hazard boundaries or live alerts. Species, seasons, weather and local closures vary. No result or missing warning is a guarantee of safety. Language does not change the country.

United Kingdom

Use the correct guidance for Scotland, England, Wales or Northern Ireland. Scotland follows the Scottish Outdoor Access Code; the Countryside Code linked here covers England and Wales. Northern Ireland has separate local access arrangements. Adders are native to Great Britain, not Ireland.

Browse by season

Snake bites: adders and other snakes

A suspected venomous bite is an emergency, even without visible punctures or immediate illness.

Ticks and parasite prevention

Check after walks and remove attached ticks promptly using the correct tool.

Blue-green algae and harmful blooms

Possible contact with harmful algae needs an immediate veterinary call; do not wait for symptoms.

Toxic plants, fungi and berries

Do not use taste, a photograph or an identification app to decide whether something is safe to eat.

Bees, wasps and insect stings

Mouth or throat stings, multiple stings, rapidly increasing swelling or allergic signs need an immediate veterinary call.

Processionary caterpillars

Suspected contact, particularly with the mouth or eyes, needs prompt veterinary advice. Breathing difficulty is an emergency.

Livestock and horses

Avoid close encounters. A calm dog can still alarm livestock, and a kick or crush injury may be serious.

Wildlife encounters

Give wildlife space. Dog-friendly access does not mean that chasing, feeding or close contact is safe.

Coasts, jellyfish and seawater

Plan for tides and currents; do not enter dangerous water to rescue a dog.

Contaminated water and leptospirosis

Water that looks clear can carry infection or contamination. Bring drinking water.

Heat, cold, snow and ice

Adapt the outing to the individual dog, wind, wetness, humidity and effort—not a universal temperature threshold.

Grass seeds, awns and foxtails

A small seed can penetrate skin or lodge in an eye or ear. Early removal by a vet matters.

Acorns, conkers and autumn scavenging

Fallen seeds and nuts are not dog toys or treats. Keep walks free from scavenging.

Common questions

Does no warning mean a walk is safe?

Can I use this without sharing my location?

Yes. Select country and region manually. Location permission and analytics consent are separate; neither is required to read the guidance.

Should I wait for symptoms after a suspected snake bite or harmful-algae exposure?

No. Call a vet immediately and follow the relevant first-aid guidance while arranging care. A dog looking well does not rule out serious harm.

How we use evidence

We use veterinary and official sources for the claims they support. Regional notes are conservative editorial signposting, not measured risk scores. Where advice depends on species, equipment or exposure, we say so rather than combine incompatible first-aid instructions. Local prevalence, antivenom stocks and individual service availability are not verified here.
