Nederlandse Kooikerhondje
The Nederlandse Kooikerhondje is a small, cheerful sporting dog with a distinctive orange-red and white coat and characteristic black earrings — long black-tipped feathering on the ears that gives the breed a uniquely elegant appearance. Originally bred to lure ducks into canal-based trapping systems called koois in the Netherlands, the Kooiker is an active, intelligent dog with a strong play drive and a natural talent for enticing birds with its wagging, feathered tail. This unusual hunting method required a dog that could work independently at a distance, be quiet and controlled, and switch between patient waiting and enthusiastic movement — traits that translate into a versatile, engaged companion. Kooikers are typically friendly and affectionate with their families but can be genuinely reserved with strangers, sometimes to the point of shyness if not properly socialized. Early and ongoing socialization is important to develop a confident adult dog. They are intelligent and enjoy learning, responding well to positive training methods, but they have a sensitivity that makes harsh corrections counterproductive. Exercise needs are moderate — they are active dogs but not hyperactive, and about 45 to 60 minutes of daily activity including walks, play, and mental games keeps them satisfied. They get along well with other dogs and can live with cats when properly introduced. The breed coat requires regular brushing but is otherwise self-maintaining and should never be trimmed. Kooikers are adaptable to various living situations including apartments, provided their exercise and socialization needs are met.
History
The Nederlandse Kooikerhondje has been depicted in Dutch paintings since the 16th and 17th centuries, including works by Jan Steen and Rembrandt, reflecting its long history as a duck-decoying dog in the Netherlands. The dogs worked in koois — elaborate canal-based duck traps where the Kooiker would lure ducks by playfully waving its bushy tail along the screens of the trap, drawing curious ducks deeper into the funnel-shaped canal until they could be caught. By the end of World War II, the breed had nearly vanished, with fewer than 25 dogs remaining. Baroness van Hardenbroek van Ammerstol led the rescue effort, rebuilding the breed from these few survivors. The AKC recognized the breed in 2018.

Care Guide
The medium-length coat requires brushing two to three times weekly to prevent tangles, particularly in the ear feathering and leg furnishings, but should never be trimmed or clipped as the natural coat texture is self-cleaning and weather-resistant. Exercise needs are moderate at about 45 to 60 minutes daily, ideally including a mix of walks, retrieving games, and mental stimulation through training or puzzle toys. Socialization must be deliberate and gentle — flooding a shy Kooiker with overwhelming experiences backfires, so exposure to new people and situations should be gradual and positive. Their sensitivity makes them excellent candidates for positive-reinforcement-based sports like rally, agility, and nosework. Due to the breed genetic bottleneck, health testing of breeding stock is particularly critical, with reputable breeders testing for all known breed-specific conditions.
Common Health Issues
- von Willebrand's DiseaseA hereditary blood clotting disorder that causes prolonged bleeding from wounds, surgery, or heat cycles. DNA testing identifies carriers, and affected dogs should have their condition noted for any surgical procedures.
- Hereditary Necrotising MyelopathyA progressive neurological condition causing hind limb weakness and paralysis, typically appearing in young to middle-aged dogs. A DNA test exists, and responsible breeders test all breeding stock to avoid producing affected puppies.
- Patellar LuxationDisplacement of the kneecap from its normal position, causing intermittent lameness and a characteristic bunny-hopping gait. Lower grades may be managed with weight control and exercise modification, while severe cases require surgical repair.
- Eye ProblemsThe breed is predisposed to several eye conditions including cataracts and distichiasis. Annual ophthalmologist examinations help catch conditions early, and breeding stock should be cleared through CAER testing.
