    Abstract / Zusammenfassung

    67 German Shepherds took part in the third phase of our study. We achieved usable results from 50 clogs, 30 of them privately owned and 20 belonging to the police force.
    Each clog, guided by its reference person, completed the obstacle course. The clogs were filmed while completing the course, as weIl as tell minutes before and tell minutes after finishing it.
    We chose four different kinds of obstacle für the test, to stimulate the acoustic, visual and tactile sense as weIl as the sense ofbalance.
    The results refer to the "grid-stair" which is a 90 cm x 200 cm steel grid structure. The clogs climb onto it by using five steps, each 18 cm high and 20 cm deep. They cross the 90 cm high bridge and descend on a sloping plane. The whole structure is made of standard 4 cm x 4 cm flat steel grid.
    The clogs showed obvious differences in their behaviour even before reaching the grid-stair, when taking their first step, and while crossing it. Depending on the war the clogs handled the obstacle and considering the differences in their behaviour the clogs were divided into four groups, or four "behaviour types".
    The results obtained from the time series analysis of the electromyogram, the skin potential, the sympathetic part of the heart rate and analysis of its regulation were compared within these four "behaviour types". This paper presents the grade of stability and instability of regulation between the groups.
    Significant correlations between the "type of behaviour" and the "type of regula- tion" can be demonstrated.
