The word “Kooikerhondje” looks as though its pronunciation will be so difficult that most people don’t even try. Instead, they call this engaging canine a “cookie hound.” Really, though, the pronunciation isn’t that hard. Kooikerhondje is pronounced “COY-ker-HUND-che,” and means “little duck-trapper dog” in Dutch. Kooikerhondjes were originally working dogs, bred in the Netherlands sometime before the 16th century. Their job was to lure ducks into partially submerged decoys, allowing human hunters to target the fowl more easily.
The breed remained popular in its native Netherlands until after World War I, when improvements in guns made duck decoys obsolete. By 1939, Kooikerhondjes had become all but extinct, but in 1940, the Baroness von Hardenbroek van Ammerstol began breeding them as an act of resistance and national pride in the midst of the Nazi occupation of the Netherlands. The breed is recognized by the American Kennel Club as part of its Sporting Group. Other names for the Kooikerhondje include cookie hound, Kooiker, and Dutch Spaniel. The breed is rapidly gaining popularity throughout the U.S. and Canada.
3 Pros And Cons Of Owning a Kooikerhondje
| Pros | Cons |
|---|---|
| They’re playful: Kooikerhondjes are smart and sociable, so they take a particular delight in playing games. Whether it’s fetch, tug-of-war, or frisbee with their human families or barn hunts, dock diving, lure coursing, and agility, or competing against other dogs, Kooikers are always up for a romp. | They can be medically fragile: All Kooikerhondjes alive today are descended from the 38 dogs originally bred by Baronesse van Ammerstol. That means that Kooikerhondjes have a higher than average risk of inheriting genetic diseases. If you’re interested in Kooikerhondje puppies, make sure you deal with a responsible breeder who understands the importance of genetic testing. |
| They’re adaptable: Kooikerhondjes are athletic because they were bred to be working dogs, but you won’t have to run them until they drop from exhaustion to keep them from acting out destructively. They’re happy to take their exercise cues from you. They’re also equally happy living in small apartments or large farmhouses. | They have a high prey instinct: Dutch Spaniels were bred to hunt ducks, so naturally, they like to chase smaller animals that run from them. With proper socialization and training, they can learn to overcome this tendency, but it’s never wise to leave a Kooiker alone with a cat or other small pet it doesn’t know. |
| They’re quietly demonstrative: Kooikerhondjes are affectionate dogs, but they’re not needy. They’re content just to hang out and chill in your presence. | They shed: Kooikerhondjes shed a fair amount throughout the year, but in the early spring and early fall, shedding is a particular problem. This is not a dog you’ll want to own if someone in your family has allergies. |

Size And Weight
Kooikerhondjes are small dogs. Adult males grow to a height between 15 and 16 inches, while females grow to a height between 14 and 15 inches. Adults of both sexes generally weigh between 20 and 24 pounds.
Common Health Issues
Healthy Kooikerhondjes can be expected to live between 12 and 14 years. Because their breeding pool over the past 80 years has been relatively small, they are prone to hereditary canine diseases such as epilepsy, necrotizing myelopathy, von Willebrand’s disease, patellar luxation, cataracts, and kidney diseases. Responsible breeders know how to encourage genetic diversity even within a limited gene pool to reduce the incidence of serious illnesses among Kooikerhondjes.
Temperament

Kooikerhondjs are keen observers of human behavior and are easily stressed by aggressive behaviors.

Kooikerhondjes have cheerful, good-natured personalities. They won’t be making incessant demands upon your attention. They’re keen observers of human behavior and will wait to play until they see their human is in the mood. One common trait many Kooikers share, however, is that they’re easily stressed by aggressive behaviors. They shy away from raised, argumentative voices and loud, unruly children. While they are not aggressive toward strangers, they can be standoffish. It typically takes a while to earn a Kooikerhondje’s trust.
How To Take Care Of Kooikerhondjes
With their black-tipped ears and silky white coats dappled with orange spots, Kooikerhondjes have a distinctive appearance that requires regular grooming to look their best. Kooikers also have dietary, exercise, and training needs specific to their breed.
The Best Dog Food

Kooikerhondjes’ diet should depend on how much exercise they get daily.

Kooikerhondjes like to eat, which means they can pack on extra pounds fast if their activity levels aren’t high enough to burn off the calories they take in. Their dietary intake really should depend on the amount of exercise they get. If you regularly play frisbee and flyball with your pet, he will need more food than if you merely take him for a few daily walks around the block. To stave off the many health problems that can be a concern with this breed, talk to the vet about any ingredients to look for or avoid when picking out the perfect food. Many dogs thrive on the more complete nutrition that accompanies less processed raw and freeze-dried dog food.
One cup of high-quality kibble once a day is a good baseline for an adult Kooikerhondje, but consult with your vet if your Kooikerhondje is getting a lot of exercise. Kooikerhondje puppies from three to six months old will need to eat three times a day, while puppies between the ages of six months and one year will need to eat twice a day. Once your Kooikerhondje celebrates her first birthday, you’ll only have to feed her once a day.
Maintenance And Grooming

You’ll need to brush your Dutch Spaniel’s medium-length orange and white coat several times a week to keep it from becoming matted and tangled. Brushing regularly will also help minimize the amount of orange and white dog hair that collects on your furniture and carpets because shedding is an issue with these dogs. Brush the coat with a pin brush and work out any particularly unruly knots with a comb. Pay particular attention to the juncture where limbs join the body because that’s where knots tend to form. Using a spray-on conditioner regularly will also help keep the coat silky and manageable, which reduces shedding.
Kooikerhondjes were bred to be water dogs, so they don’t need to be bathed very often. They like to swim, and you should make sure to give them a very thorough rinsing in freshwater any time they’ve spent an afternoon at a lake or in a pool. Brush their teeth daily, and trim their nails every three to four weeks as needed.
Training

A Kooikerhondje dog should begin training early, and consistency is important.

Kooikerhondjes are very eager to please. However, like all dogs that were bred for hunting, their prey drive and natural independence can occasionally get in the way of obedience. This is why early, consistent training is very important for Kooikerhondjes. In fact, every member of the Kooikerhondje’s human family should participate as much as possible in the dog’s training so that the dog understands his or her position in the hierarchy.
Exercise
As working dogs, Kooikerhondjes have a lot of energy; however, they adapt very easily to the exercise preferences of their owners. If you’re someone who likes to be physically active, your Kooikerhondje will be delighted to keep you company. If your lifestyle is more sedate, that will work, too. At a minimum, though, your Kooikerhondje should have half an hour of vigorous outside exercise every day. Kooikerhondjes are particularly fond of seek-and-retrieve games.
Puppies
The average Kooikerhondje litter size is five to seven puppies. Puppies are expensive — in the U.S., you can expect to pay between $3,000 and $3,500 for a Kooikerhondje puppy, while in Canada, where the breed is even rarer, you can expect to pay more. The reason for this is that reputable breeders will go to great lengths to ensure that the puppy they’re selling you is genetically sound. In fact, it is likely that if you buy a puppy for less than this amount, you will end up with a pet who’s prone to a hereditary disease.

Kooikerhondjes And Children
These dogs do well with children, as long as the children are ones the dog already knows. The dog is likely to be standoffish with unfamiliar children and should be kept away from toddlers who might try to pull his ears or tail, as this will stress your pet out.
Dogs Similar To The Kooikerhondje
The Petit Basset Griffon Vendéen, Tibetan Terrier, and Poodle all have things in common with these dogs.
- Petit Basset Griffon Vendéen: The Petit Basset Griffon Vendéen (PBGV for short) is about the same height as a Kooikerhondje, though it weighs a little bit more. Like Kooikers, PBGVs have happy dispositions and love to play.
- Tibetan Terriers: Tibetan terriers also stand approximately the same height as Kooikers. They are stockier, though. While not as mellow and laid back as Kooikerhondjes, they are just as quick at learning tricks, and they love to play.
- Poodles: Like Kooikerhondjes, Poodles love to swim. In fact, they were originally bred to retrieve ducks and other waterfowl after the birds were shot. You might say that the job Kooikerhondjes began, Poodles finished.
Famous Kooikerhondje
Prince William I of Orange (William the Silent) was the leader of the Dutch revolt against the rule of the Spanish Habsburgs in the 16th century. According to legend, his dog Pompey saved him from an assassination attempt by alerting him to danger while he slept. While some sources associate Pompey with the Kooikerhondje, the breed as recognized today was not established until the 20th century. A statue of Pompey curled up at William I’s feet is included in his effigy.
