Origin and purpose
Non-Sporting (AKC). Origin: Norway.
One of the rarest breeds, with an extreme in-breeding history.
What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the owner's job is to give it somewhere to go.
Temperament and training
Stated temperament: Alert, energetic, unique — six toes per foot, flexible neck
Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.
Feeding
Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.
Exercise and enrichment
Stated requirement: Moderate
Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.
Climate and living conditions
Stated suitability: Poorly suited to hot climates; adapted to cool, cold conditions.
Ageing and senior care
Life expectancy: 12–14 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early.

Before you take one home
- Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.
