A 75-year-old register of newborn puppies is helping prevent genetic illnesses in a Dutch breed of dog. It means breeders of the Kooikerhondje dog can carefully select a dog’s parents according to their history of illnesses. There are around seven thousand Kooikerhondje dogs in the world. But despite their small genetic pool, the Dutch breed is as healthy as many other breeds with a much larger population. The continuous 75 year registration of Kooikerhondje dog health profiles is helping the breed to avoid genetic illnesses. The Nederlandse kooikerhondje (pronounced NAY’-dehr-lahn-seh KOY’-kehr-hahnd-jeh) goes back hundreds of years in Holland. The smallish, light brown-and-white, spaniel-style dog is as much a part of Dutch identity as tulips, windmills and wooden clogs.
