Yes. According to the Rights of Public Access dogs must be kept on a leash from 1 March-20 August. Animal life is at its most sensitive to disturbance just then from even the most peaceful pet dog. Outside these times you must keep close watch over your dog, so that it doesn’t scare the wildlife. Special rules apply, according to the Nature Conservation Act, when taking your dog into a national park area. These rules can be found on the website for the respective county’s administration committee (länsstyrelse). For Norrbotten you can find the information at www.fjallen.nu
Dogs are welcome free of charge at STF's mountain stations. There are a limited number of dog friendly rooms so we recommend to make a reservation in advance. There are different room types, a room on your own or a room that you share with other dog owners and dogs.
