How the Lancashire Heeler Calculator Works
1
High-Sensitivity Dynamic Modeling
We use a proprietary High-Sensitivity Dynamic Model calibrated specifically for Lancashire Heeler 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.
2
Maturity Window Calibration
A Lancashire Heeler typically reaches its full skeletal structure around 12 months. Our algorithm applies a specific maturity multiplier that adjusts the projection as your puppy approaches this target window.
3
Standard Deviation Check
Every projection is cross-referenced against the Lancashire Heeler breed standard (9–17 lbs). While estimates can begin at 6 weeks, data collected after the 12-week mark provides the highest statistical confidence.
