The dog is often a nice companion during a hike. However, it is important to follow the Swedish Environmental Protection Agency's guidelines that the dog has to be kept on a leash, at least during the period March 1 - August 20. This is to protect the wildlife and their young.
Even during other periods of the year, the dog should be kept under supervision to prevent it from hunting wild.
Also show consideration for other people along the trail. Keep in mind that other people can be afraid of dogs.
When passing through parts with gracing animals extreme caution is required. Cows and horses are often curious or afraid of dogs and can become both nervous and angry.
Therefore, always keep a good distance and keep the dog on a leash.
