How the Portuguese Water Dog Calculator Works

1

High-Sensitivity Dynamic Modeling

We use a proprietary High-Sensitivity Dynamic Model calibrated specifically for Portuguese Water Dog 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 Portuguese Water Dog typically reaches its full skeletal structure around 15 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 Portuguese Water Dog breed standard (35–60 lbs). While estimates can begin at 6 weeks, data collected after the 12-week mark provides the highest statistical confidence.
