Breed, sex, and litter effects in 2-month old puppies’ behaviour in a standardised open-field test

Abstract A considerable number of studies have reported differences among dog breeds with respect to their genetic profile, cognitive abilities or personality traits. Each dog breed is normally treated as a homogeneous group, however, researchers have recently questioned whether the behavioural prof...
