Coasts, jellyfish and seawater
Plan for tides and currents; do not enter dangerous water to rescue a dog.
All outdoor hazardsWhat to do now — and avoid
Call the vet after significant seawater or sand ingestion, a sting or submersion. Do not rub a jellyfish sting or apply improvised treatments; species-specific advice is needed. Stay on land during a rescue emergency. In the UK call 999 and ask for the Coastguard for coastal danger; this is not a veterinary helpline.
Signs to watch for
Repeated vomiting, diarrhoea, weakness, unusual behaviour or breathing difficulty after seawater, a sting or submersion need urgent veterinary advice.
Where you might encounter it
Cliff edges, sand ingestion, sea drinking and washed-up jellyfish are hazards. Dead jellyfish can still sting.
Prevention
Check tides, closures and conditions. Keep control near cliffs; carry fresh water and prevent scavenging. Never force swimming.
What veterinary care may involve
Fluid or salt disturbances, airway problems and stings require individual assessment. Apparent recovery after submersion does not rule out harm.

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.
Canada
Check the province or territory and the individual park before setting out. Parks Canada’s bear-country advice includes physical control of dogs and considering leaving them with safe care. It is not a rule for every Canadian space. Local wildlife encounters, water alerts and winter conditions need destination-specific checks.
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.
