Kooikers are intelligent and eager to join in any offered activity. While generally cautious in new situations, they are self confident, good natured & alert in familiar surroundings. They were bred to work along side their owner luring ducks into nets. They also killed vermin and have a strong prey drive. Most are active enjoying retrieving, playing and swimming in water yet also are happy to lie on the couch and relax with their family.
A young Kooiker that is not given sufficient outlet for expending its energy may find its own by digging or chewing or whatever else comes to his active mind. Young dogs in particular need maximum companionship with their owners each day. This is the opportune time for learning which activities are acceptable and which are not. A properly raised Kooiker that is well exercised physically and mentally will mature into a quiet, well behaved family member.
Kooikers are calm and loyal companions not given to noisy hyperactivity. They can be reserved with strangers and sensitive to loud noises and sudden movements. It is important to properly socialize a young Kooiker and expose him to many varied environments. Many require a large personal space and do not appreciate other dogs entering it. If properly socialized they learn to ignore other dogs and behave politely when encountering other polite dogs. They are always watchful. They are reserved toward strangers, children and other dogs. But once they accept someone, they are friends for life.
Kooiker are highly trainable but easily bored by repetitive methods. Their sensitivity and desire to please makes them much more vulnerable to harsh corrections or repeated failures than the other sporting breeds. They respond better to praise than to punishment. However, they do require firm boundaries and clear rules.
The Kooiker tends to be a “one person” or “one family” dog. While not all suited to life with small children, Kooikers that are socialized to children at an early age will enjoy them. In turn, children who respect animals will find Kooiker to be willing playmates.
