The Nederlandse Kooikerhondje's moderate size makes it an excellent candidate for car travel, and many owners find that their dogs become enthusiastic road trip companions with proper conditioning. The key to successful car travel begins with crate training or harness acclimation well before the first long journey. A properly sized travel crate secured in the cargo area or back seat provides the safest containment option, protecting the dog in the event of a sudden stop or collision while giving it a familiar, den-like space to settle into during the drive.
For owners who prefer not to use a crate, crash-tested dog harnesses that attach to the vehicle's seatbelt system offer an alternative restraint method. Regardless of the chosen method, unrestrained dogs should never be allowed to ride in the front seat, where airbag deployment poses a serious injury risk, or to hang their heads out of open windows, which exposes them to debris, insects, and the possibility of jumping or falling from the vehicle.
Kooikerhondjes are an active breed that benefits from regular breaks during long drives. Planning stops every two to three hours allows the dog to stretch, relieve itself, and drink fresh water. These breaks are also valuable for maintaining the dog's comfort and reducing travel-related anxiety. Owners should always use a leash during rest stops, as the breed's prey drive can lead to sudden pursuit of birds or small animals in unfamiliar environments.
Motion sickness can affect some Kooikerhondjes, particularly young dogs that are still acclimating to car travel. Feeding a light meal several hours before departure rather than immediately before can help reduce nausea. For dogs with persistent motion sickness, veterinarians can recommend appropriate medications or supplements. Gradually increasing the duration of car trips over time, starting with short drives to pleasant destinations, helps build positive associations with vehicle travel.
