The Lapinporokoira is a medium-sized dog, with medium length fur in a double coat. Ears are pricked (standing up; drop ears are a disqualifying fault.) Colour is generally black or dark grey or brown, with a lighter shade on the head and lower parts of the body, often with white markings. Height should be 51 cm (20 in) at the withers for males, 46 cm (18 in) for females. Males and females should look distinctly different. Weight is between 55-65 pounds, males usually heavier than females.

The breed standard states that the dog should be calm, friendly, and docile, but also energetic. Most herding breeds need to be given regular exercise. The temperament of individual dogs may vary.
