How it works & sources

FurWeather estimates traits from the genetics of the two parent breeds and the cross generation. Everything below is a probability, not a promise — littermates can and do differ.

The two coat genes we model

Furnishing — RSPO2. Poodles carry two furnishing alleles (the moustache/eyebrow "doodle look", linked to low shedding); most non-Poodle parents carry none. Furnishing is dominant, so F1 and F1B puppies are reliably furnished. At F2, roughly 1 in 4 puppies can be unfurnished — a flat "improper" coat that sheds like the non-Poodle parent.

Curl — KRT71. One curl allele tends to give a wavy/fleece coat; two give tighter curls. More backcrossing to a Poodle (F1B, F1BB) shifts the odds toward curly.

Size

Adult size is treated as roughly additive and weighted by the puppy's percentage of Poodle genes, then widened to reflect litter variation. Size is the most predictable trait; coat and shedding are less so, which is why each result carries its own confidence level.

Temperament

Energy, trainability, affection and sociability are blended from published breed-club trait profiles of the two parents. Individual personality still depends on the specific dog, socialisation and training.

What this is not

This is an educational estimate for prospective owners, not veterinary or breeding advice, and not a substitute for a DNA test on a specific dog. We do not encourage breeding for profit over health; avoid high-risk pairings such as merle × merle.
