Episode 03 – Selecting for Temperament

This episode dives deep into the science behind temperament, genetics, and selective breeding. John explains how dog behaviour is inherited, why traits like aggression, scent ability, or a Labrador’s loving nature have a genetic foundation, and how breeders use complex statistical tools to select for specific traits. The conversation also explores the crucial role of early-life development windows, the risks of breeding for aggression, and how behaviour can be both genetically anchored and environmentally modified. A must-listen for anyone interested in working dogs, training, or the science of canine temperament.
