The Kooikerhondje or Kooiker Hound, is a small spaniel-type breed of dog of Dutch ancestry that was originally used as a working dog, particularly in duck hunting and tolling. Kooikers were popular in the 17th and 18th century and appeared in the paintings of Rembrandt and Jan Steen. The breed is rapidly gaining popularity in the United States, Canada and Scandinavia, where it is still relatively unknown.
These dogs are around 35 to 40 cm (14 to 16 inches) high at the withers with a nearly square body that is slightly longer than their height at the shoulders. Depending on the gender and the height, a Kooikerhondje is not supposed to weigh more than 9-11 kilograms (20 to 24 lbs). They have medium long, hanging ears with wispy tips, known as earrings, that are set close to the head and they have long, feathered tails with a white plume. The breed has a waterproof, medium long coat that doesn't hold much dirt and is easily cleaned by a simple brushing. They have shiny bicoloured coats that can take up to 2 years to mature, often predominantly white with orange-red plates. The fur is medium long and either slightly wavy or straight. For conformation showing, dogs with black ear tips and white tails are preferred.
Cheerful, good natured, friendly, quiet, well-behaved, and alert; those are terms that are used to describe the Kooikerhondje. Depending on its domestic environment,it is kind, happy and lively. They are also intelligent, attentive and more than willing to please their owner. The Kooikerhondje adapts to situations rather quickly, changing his behavior from quiet to lively when the situation allows him to be. He will not always immediately like strangers, instead choosing to retreat. But once he warms up to someone, the trust will be there for the rest of his life. The Kooikerhondje can make a fine apartment dog if exercised regularly, but a fenced yard will be more ideal. He has a high energy level, yet is usually quiet when indoors.
Kooikers have good appetites and a tendency to put on weight easily. Their life span is 12–14 years. As Kooikerhondjes have a small genetic base, hereditary diseases were somewhat prevalent earlier. These include:
- von Willebrand's disease, a blood clotting disorder 
- Cataract and other eye diseases 
- Patellar luxation 
- Hereditary Necrotising Myelopathy (ENM) a fatal neurologic disease 
Today (due to a lot of hard work in the national clubs) most Kooikers used for breeding are free from von Willebrands disease (most national clubs require both male and female dogs to be free from this disease to be allowed to breed). Patellar luxation is not major problem in most countries at the moment, but is kept under a close watch to prevent it from becoming a problem again. In the Netherlands, eye tests are available and all breeders breeding according to the breed club's rules have to test their dogs. Only dogs that are free of eye diseases are allowed to be used for breeding. Testing for ENM became available in 2012. In the Netherlands, only dogs who are tested may be used for breeding. Only allowed breedings are Free x Free or Free X Carrier. Carrier to Carrier should never be done as the risk of this fatal disease is high. Puppy purchasers should inquire about the ENM status of the parents. 
The Kooikerhondje was developed in the Netherlands around the sixteenth century to be a tolling breed. They were used to lure and drive ducks into 'kooien' (cages in the form of canals with traps at the ends), where the hunter (the so-called Kooiker) could easily catch the fowl. The dogs that were used by the Kooiker for this kind of hunting technique, were referred to as the 'Kooiker's hondjes' (literally: Kooiker's dogs). Eventually this led to this dog being called Kooikerhondje.
The breed almost became extinct after World War II until Baroness van Hardenbroek van Ammerstol rescued it. The breed was only officially recognized by the Raad van Beheer, the Dutch Kennel Club, in 1971 and has since been imported into other countries and recognised officially. The breed is still relatively unknown in North America and not yet recognized as a breed in the USA or Canada, although it has been accepted into the AKC's FSS program and is assigned into the Sporting Group. In the United States, both the UKC and ARBA recognize the breed.
In January 2013, the Kennel Club announced it was re-classifying the Kooikerhondje from the Gundog group to the Utility group effective from January 2014. The decision was reached after discussions with the UK breed clubs and unanimous agreement was achieved.
Some historians believe the Kooikerhondje may have possibly played a part in the development of the Nova Scotia Duck-Tolling Retriever.
