From 1989 until 2003, the Swedish Sheep Dog Society used astandardized method, HBC (Herding Behavior Characteri-zation), to characterize herding behavior of individual bordercollies. The dogs’ typical herding behavior was describedusing predefined scales. During the period, 2 different record-ing protocols were used. In total, 2700 dogs participated.Heritability estimates for the 17 traits of the earlier versionof the HBC ranged from 0.14-0.50 (average 0.30), allstatistically significantly different from zero. Correspond-ing heritabilities for the later version were substantiallylower. There are several possible explanations for thisfinding. For example the scales, that is, the way the traitswere recorded, might have had a less appropriate construc-tion in the later version.A factor analysis suggested that the traits measured can beexplained by 4 overall traits with heritabilities ranging from0.30-0.55. Owing to the moderate to high heritabilities, itwould be possible to accomplish effective selection ofbreeding animals for most of the measured traits.

environments. This study aims to assess the effects of a newHuman Familiarization and Training Program (HFTP, basedon positive and more frequent dog-handler interactions andtraining) on fearfulness and aggressiveness of militaryworking dogs (MWDs). We predicted that an experimentalgroup of dogs submitted to this program (5 EG dogs) wouldbe less fearful and aggressive during an aggression test than acontrol group of dogs (CG dogs). We found a significantdecrease of fearfulness (higher posture and less yawning) andaggressiveness among EG dogs. We interpreted this decreaseof fearfulness and aggressiveness as a positive effect of theHFTP on the dogs’self-confidence and welfare, as it offered amore social (intra- and interspecific) and environmentallyenriched experience and induced a better working dog-handler relationship.

TEMPERAMENT TESTING, FROM PUPPIES TO ADULTHOODC. Diederich*, J.-M. GiffroyLaboratory of Anatomy and Ethology of DomesticAnimals, Department of Veterinary Medicine, Faculty ofSciences, University of Namur (FUNDP), Namur, Belgium*Corresponding author: [email protected]
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. Stage(2): Summary of the information from the aforementionedvariables and definition of new variables by means of Prin-cipal Component analysis (PC). Stage (3): Prediction of
