How the Flat-Coated Retriever Calculator Works
1
High-Sensitivity Dynamic Modeling
We use a proprietary High-Sensitivity Dynamic Model calibrated specifically for Flat-Coated Retriever 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 Flat-Coated Retriever typically reaches its full skeletal structure around 18 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 Flat-Coated Retriever breed standard (55–80 lbs). While estimates can begin at 6 weeks, data collected after the 12-week mark provides the highest statistical confidence.
