Adult weight from the American Kennel Club’s Nederlandse Kooikerhondje breed page, checked 1 October 2026. Individual dogs vary, and a healthy weight for your dog is one for your vet to judge.
How the estimate works
The calculator takes your puppy’s weight, divides it by their age in weeks, and multiplies by 52. It’s a quick guide, not a growth chart: puppies gain fast early on and slow down as they near adult size, so the answer shifts as they grow. That’s why the result is shown next to the breed’s adult weight. If the two disagree, trust the breed’s weight and your vet.
