Algvakten — dog swim safety

Algal blooms can be deadly for dogs — often within hours. Algvakten helps you check the water before your dog goes in.

HOW IT WORKS • Official advisories from the Swedish Agency for Marine and Water Management for ~2,600 Swedish bathing sites, updated daily. • The home screen shows your saved places and the nearest bathing sites with distances. • The map shows advisories across the country — with filters for advisories only, or only places with no official monitoring.

ASSESS IT YOURSELF The most dangerous waters — small lakes and ponds — rarely have any official monitoring. The checklist guides you step by step through what to look for on site.

EMERGENCY Symptoms of algal poisoning, what to do immediately, and a map to the nearest animal hospital.

DOG ACCESS Many public bathing sites ban dogs during the bathing season. Algvakten shows it.

ALGVAKTEN PRO An optional one-time purchase supporting development: history and seasonal patterns, last known status offline, and sync between your devices. Everything safety-related is and stays free.

Note: advisory texts come from the Swedish authority and are shown in Swedish, as official water-safety wording should not be machine-translated.

Algvakten never says "safe". No known warning does not mean the water is clean — always assess it yourself before your dog swims.
