Kooikerhondje is a charming orange-red parti-coloured dog with an alert and gentle expression. It is compact and medium-sized with a nearly square body, which is longer than it is tall. It has a curved skull that is as long as its muzzle, a strong jaw with a perfect scissor bite, a defined stop, almond-shaped brown eyes, and feathered pendant ears that are proportion with its head. Its neck is well muscled and moderately long, and body is muscular with a deep chest and well-sprung ribs. The Kooiker weighs 20 to 24 pounds and stands 35 to 42 centimetres.
The Kooiker’s coat is fine in texture, medium in length and close fitting, which can be straight or wavy and never curly. It has a shorter coat on its head, front part of the legs and feet, as well as a well-developed undercoat. Finally, its tail is well feathered. According to KC standards, the accepted colour is white with patches of clear red-orange; white blaze is preferred.
Taking care of a Kooikerhondje’s coat is generally easy as it does not have any special grooming requirements. Since it sheds steadily throughout the year, brushing once or twice a week is needed, which becomes frequent during the spring and autumn when it sheds more. Attention should be given to its feathering and longer hair to remove tangles and avoid matting. It can be bathed as needed, about 3 or 4 times a year so its natural oils won’t be stripped off. As for other grooming aspects, brush its teeth two to three times a week to avoid tooth and gum problems and check its ears for wax build-up, redness and foul odour. Also trim its nails when you hear clicking sounds on the floor because overgrowth can be uncomfortable and cause cracking.
