Behavioral temperament can be defined as the emotionalcharacteristic of an individual. Among other properties,temperament is precocious and stable across time andsituations. Among temperament traits, boldness andaggressivity are traits that need special attention whendog-human relationships are considered. As part of effortsto help preventing biting by dogs, it appears important tobe able to assess individual level of aggressiveness asearly as possible in dogs. This early assessment will helpproposing individually tailored education and training aswell as best fitted dog placements. Our study was aimed atdetermining the stability of temperament over the courseof behavioral development in domestic dogs, Canis famil-iaris. The behavior of 31 dogs was analyzed from birth tothe age of 15 months in a three-stage research plan: Stage(1): Identification, among a set of 520 behavioral varia-bles, of the ones which best differentiate dogs.
