Stabyhoun size at maturity
A fully grown Stabyhoun stands about 19.5 to 21 inches at the shoulder and weighs roughly 40 to 55 pounds. Males are usually close to 21 inches and 50 to 55 pounds, females nearer 19.5 to 20.5 inches and 40 to 45 pounds. The body is longer than it is tall, strongly but never heavily built, with a deep chest and a silky, moderately long coat that lies close enough to reveal the honest outline beneath.
For orientation, a Stabyhoun stands a little taller than a typical springer spaniel and carries a few more pounds, without approaching retriever mass. It is the sort of dog most people instinctively file as properly medium: substantial enough to work a full day in the field, light enough to lift into a vehicle with effort rather than equipment. In a breed this rare, those moderate numbers are also remarkably consistent from dog to dog.
The Dutch all-rounder's balanced build
The Stabyhoun comes from Friesland in the Netherlands, where farmers of modest means needed one dog that could point, retrieve, hunt moles and polecats, guard the yard, and live gently in the house. That one-dog economy produced the balanced, moderate build you see in the fully grown Stabyhoun: no exaggeration anywhere, because a specialist's extremes would have failed at some other farm job. The slightly long body, strong feet, and weather-resistant coat all serve versatility.
A steady path to full size
A Stabyhoun puppy grows without drama, reaching most of its height by ten to twelve months and filling out to adult weight and chest depth by around eighteen months to two years. Growth is even rather than gangly, though adolescent males in particular can look a touch rangy before the final substance arrives. The silky coat also lengthens and gains its adult feathering on the legs, chest, and tail across the same period.
Living with a moderate, devoted gundog
At 40 to 55 pounds, a fully grown Stabyhoun needs the ordinary provisions of a medium-large dog: a secure garden, a vehicle setup that handles a wet dog after work, and daily exercise with something for its nose and brain to do. Gundog games, tracking, and long country walks suit the breed's design far better than repetitive ball work alone. At home the Stabyhoun downshifts completely, which is the ancient bargain of the farm dog: full worker outside, quiet companion inside.
Availability is the practical catch in choosing this breed. Stabyhouns are genuinely rare outside the Netherlands, with careful breeding and waiting lists, so your size research will likely run alongside a long, worthwhile wait. That scarcity also means breeders and breed associations keep close track of every dog, and a Stabyhoun needing a new home usually moves through those knowledgeable channels rather than general listings.
Verifying an individual Stabyhoun
Ask the breeder for the parents' measured heights and scale weights, since in a breed with this little variation those figures predict a puppy's adult size with unusual accuracy. For an adult Stabyhoun, confirm a current weight and date of last health check, and feel the body under the coat rather than trusting the tidy outline. Spending time with adults at a breed event, if you can find one, calibrates your expectations better than any chart.
When a Stabyhoun does change homes, the knowledge held by its breeder and first owner, from feeding to training to health screening, is part of the dog's welfare. Through KinsLe Transferrable Profiles, that complete profile passes to the new owner with records and routines preserved, so a gentle, routine-loving dog keeps its bearings through the move.
