Regarding vaccination frequency for dogs ("vaccination hund hur ofta"), the typical vaccination schedule for dogs is as follows:

• Puppies receive their initial series of vaccinations between 6 to 16 weeks of age, with boosters every 2-4 weeks.
• After the puppy series, dogs usually get a booster vaccination at one year of age.
• Following that, adult dogs often get vaccinations every 1 to 3 years depending on the vaccine.
• Some vaccines, such as for kennel cough, may require annual boosters.
• Vaccination schedules can vary based on regional guidelines and the dog's exposure risk.

This means that dogs ("hund") are vaccinated ("vaccination") starting as puppies and then typically boosted ("hur ofta" = how often) annually or every few years depending on the vaccine and local recommendations.
