Icelandic Sheepdogs are predisposed to patellar luxation, cataracts, and retinal dysplasia (an inherited condition where the retina doesn't develop properly, sometimes diagnosable in young puppies) — regular eye and patella screening are standard for breeding dogs.
A quality diet in measured portions matched to this breed's genuinely high activity level.
The thick double coat sheds moderately to heavily and needs regular brushing, more during seasonal blowouts.
Highly trainable and eager to work, Icelandic Sheepdogs pick up cues quickly and need real daily activity — herding work, agility, or vigorous exercise — to stay content.
The Icelandic Sheepdog descends from dogs brought to Iceland by Viking settlers, related to the Karelian Bear Dog, and historically used to herd horses, cattle, and sheep across Iceland's terrain. It's the only dog breed native to Iceland, and its fox-like appearance — pointed ears, curled tail, thick coat — places it among the Nordic spitz breeds.
Smaller than most other herding breeds, Icelandic Sheepdogs are known for genuine affection and loyalty to family, wanting to be constantly by their people's side, alongside real herding-dog energy and intelligence.
