Dogs in Swedish Nature: Wildlife, Hunting Season and the Rules

Sweden lets a dog go almost anywhere you can walk. In return the dog must never bother wildlife or grazing animals, and you need to know the places and months where the rules tighten. Here is the whole picture on one page, season by season.

When you need this

You’re hiking or camping with a dog in forest, mountains or along the coast. Or it’s autumn, hunting season is on, and you wonder whether the dog can run. Or you’re heading for a national park, the reindeer-herding north, a lake on a hot day or a mountain hut. And, less happily, when the dog has been bitten, is ill after a swim, or has just met a wild animal.

The leash rules in nature

The national rule is section 16 of the Dog and Cat Supervision Act, Lag (2007:1150) om tillsyn över hundar och katter. It has two halves:

The practical reading comes from Naturvårdsverket (the Swedish Environmental Protection Agency), and its advice goes a step further: keep the dog on a leash near grazing animals, in reindeer grazing land, and in national parks and nature reserves, whatever the month. Chasing sheep or cattle around a field counts as harm even if the dog never bites.

The leash law has its own guide — Sweden’s leash law — with the town rules and what the statute says about consequences. For a dog in the countryside, the key point is simple: 21 August does not mean freedom. It means the start of the hunting season.

National parks, reserves and the mountains

In every Swedish national park the dog must be on a physical leash, however obedient it is, and some protected areas ban dogs entirely. The mountain parks in Lapland go further:

Nature reserves set their own rules, printed on the sign at the entrance, and many require a leash. On Skåneleden, for example, Stenshuvud, Dalby Söderskog and Söderåsen need a leash all year, and the dune reserve at Sandhammaren bans unleashed dogs. Read the sign every time.

Reindeer country

Reindeer graze across roughly half of Sweden — the north and the mountains. Here the reindeer-herding act, Rennäringslagen 93 §, says it plainly: when reindeer are in a grazing area where herding is allowed, a dog not used in herding must be kept i band (on a lead) or shut in. That applies in any month, not just spring.

Reindeer scare easily. A chased herd scatters, undoing days of herding work, and pregnant females may lose their calves or abandon newborns. Naturvårdsverket asks visitors to keep away from reindeer grazing land during calving, April to June. The legal consequences are sharp too: frightening reindeer is fineable on ordinary negligence, and a reindeer owner may kill a dog chasing the herd if it cannot be caught.

Hunting season, bears and wolves

As of 25 September 2026 the moose hunt is already on in the north (from 1 September) and opens in the rest of Sweden on 8 October. The bear licence hunt in seven counties runs until 15 October at the latest. You may still walk anywhere allemansrätten allows — see hiking during hunting season — but the dog changes the picture:

• A loose dog can be lost. The holder of the hunting rights, often the landowner, may take a dog running loose among wildlife; if it cannot be caught, the county board may decide to have it put down.
• You will meet loose working dogs. Hunting dogs in use are exempt from the chasing ban. Steady barking in one place usually means a dog holding a moose at bay with a hunter creeping in — turn away.
• Loose dogs and bears are a bad mix. A dog was involved in 12 of the 18 bear attacks on people recorded in Sweden in 1995–2007, all of them hunting dogs. SLU’s bear leaflet says to keep the dog leashed, because a panicking dog runs back to its owner — possibly with a bear behind it. See bears in Sweden.

Wolves and lynx do attack dogs, but not many. In 2025 large predators attacked 36 dogs in Sweden and killed six; wolves were behind 15 attacks, lynx 19, and a bear and a wolverine one each. SLU links the yearly swings to how many days dogs are used in hunting, and to weather and snow depth.

Adders, ticks and poisoning

Adders (huggorm) bite dogs every summer; one university animal hospital had treated 78 bitten dogs by 16 July 2025. They are active from late February or March into autumn and bask on warm, sunny days, so keep the dog on the path and away from sunny stone walls and heath edges. If a bite happens:

1. Keep the dog as still as possible, and carry it if you can — movement spreads the venom.
2. Do not bandage, cool or try to suck the wound.
3. Phone a vet immediately.

Ticks are active from about 10 °C, mainly March to November, and in southern and central Sweden they can turn up all year. SVA, the National Veterinary Institute, recommends veterinary tick products with the right indication plus coat checks — no product is a complete barrier. Details in ticks in Sweden.

Poisoning: do not call Giftinformationscentralen, the Swedish poison centre. It has not answered questions about animals since 1 July 2018. Call a vet; vets in Sweden explains out-of-hours cover, which is thin in parts of the countryside.

Swimming, beaches and algal blooms

Most dogs can swim in most Swedish lakes and along most of the coast. The exceptions are marked bathing places in summer, where towns ban dogs through local regulations:

These are examples, not national rules; check the town’s website or the sign. Swedish beaches and lake swimming cover the rest.

The bigger swimming risk is blue-green algae. Blooms come mainly in high summer and autumn and make the water blue-green or brown, sometimes grainy. If you cannot see a metre down, treat it as a warning. The poison centre notes that you cannot tell by eye whether a bloom is toxic, and that dogs that swim often and long and drink the water are at particular risk.

Symptoms — vomiting, drooling, diarrhoea, unsteady gait, itching, sore eyes — can appear within hours; in severe cases paralysis and convulsions come quickly, with liver and kidney damage, and animals die. If the dog has swum in a bloom, rinse its coat and eyes with clean water and phone a vet if it seems unwell.

Huts, shelters and cleaning up

STF mountain huts all have separate dog rooms, and the dog stays at no extra charge — but you must add it when booking, and only one person is guaranteed a place with the dog. See STF mountain huts and dog-friendly stays. Elsewhere it varies: Skuleskogen National Park’s free cabins on the High Coast Trail allow dogs but not on the beds, while Skåneleden welcomes supervised dogs at its shelters but not in its cabins.

Cleaning up: towns require droppings in public places to be picked up; Stockholm’s regulations are an example. On trails, bag it anyway near shelters, campsites and bathing places — the next person may be sleeping there.

Practical information

FAQ

Can my dog run off leash in Swedish forests?

Only from 21 August to the end of February, and only if you can see the dog and call it back before it chases wildlife. From 1 March to 20 August the law bars loose dogs where wildlife lives, which Naturvårdsverket reads as a leash. National parks and reindeer areas require a leash in every month.

Is it safe to walk a dog in Sweden during hunting season?

Yes, you may walk anywhere allemansrätten allows, but keep the dog leashed. A loose dog can be taken by the holder of the hunting rights, and loose dogs trigger most bear attacks: a dog was involved in 12 of 18 recorded in 1995–2007. The moose hunt starts on 1 September in the north and 8 October elsewhere.

Do wolves attack dogs in Sweden?

Rarely, but it happens. In 2025 large predators attacked 36 dogs in Sweden and killed six; wolves were behind 15 attacks and lynx 19. SLU links the yearly swings to how many days dogs are used in hunting, and to weather and snow depth, so loose dogs in hunting country carry most of the risk.

What should I do if an adder bites my dog?

Keep the dog as still as possible, carry it if you can, and phone a vet at once, because movement spreads the venom. Do not bandage, cool or try to suck the bite. Adders are active from late February or March into autumn, basking on warm, sunny days; one animal hospital treated 78 bitten dogs by mid-July 2025.

Can my dog swim in Swedish lakes and the sea?

Usually, yes, outside marked bathing places where towns ban dogs in summer, such as Stockholm from 1 June to 31 August. Keep the dog out of water that looks green, blue-green or grainy: dogs that swim a lot and drink the water are at particular risk of algal poisoning, and animals die of it.

What are the rules for dogs around reindeer?

When reindeer are in a grazing area where herding is allowed, a dog not used in herding must be on a lead or shut in, in any month. Reindeer are most sensitive during calving, April to June; a scattered herd can lose calves. A reindeer owner may kill a dog chasing reindeer if it cannot be caught.

Can I take my dog to Swedish mountain huts?

Yes. STF’s mountain huts house dogs at no extra charge in separate dog rooms, but you must add the dog when booking, and only one person is guaranteed a place with it. Check the park first: Abisko, Vadvetjåkka and Pieljekaise admit dogs mainly from January to April, Sarek outside January–April only on Kungsleden, and Padjelanta not at all outside those months.
