The Nederlandse Kooikerhondje – pronounced Netherlands-e Coy-ker-hond-tsje – is a spaniel-type dog that originated hundreds of years ago in Europe as a duck hunter. The breed was also a favorite of Dutch nobility. These are energetic, friendly and alert dogs that are ready for work. They have a moderate activity level, needing regular mental and physical activity to be happy. Their medium-length coat requires weekly brushing to keep it free of tangles.
