We use a proprietary High-Sensitivity Dynamic Model calibrated specifically for Belgian Laekenois development. This accounts for the biological reality that growth velocity decelerates sharply as a puppy matures, ensuring pinpoint accuracy for both 8-week-old puppies and older teenagers.
A Belgian Laekenois typically reaches its full skeletal structure around 17 months. Our algorithm applies a specific maturity multiplier that adjusts the projection as your puppy approaches this target window.
Every projection is cross-referenced against the Belgian Laekenois breed standard (45–65 lbs). While estimates can begin at 6 weeks, data collected after the 12-week mark provides the highest statistical confidence.
