本文的主要目的是分析军事工作犬（MWD）的生理（皮质醇）和行为反应。狗 (N=27) 接受了两次环境挑战（挑战 1 和 2，间隔 20 天），其中包括社交（训练）、视觉（移动玩具车）和听觉（鼓风）刺激。第二次挑战后，皮质醇水平下降回到基线。行为观察表明：这些MWD在两次视觉挑战期间表现得更加活跃，并且表现出较少的刻板行为（步调、操纵环境），而在第一次视觉挑战期间观察到半低姿势，但在第二次视觉挑战期间没有观察到。本研究表明，这组MWD仍然具有对环境挑战的适应能力（回到皮质醇水平的基线，第二次挑战期间的姿势比第一次挑战时更高）。这些结果令人鼓舞，表明狗的福利可能会减少（即刻板行为），但不会长期承受压力。 (C) 2007 Elsevier Inc. 保留所有权利。
This paper's primary objective is to analyse the physiological (cortisol) and behavioral responses of military working dogs (MWD). Dogs (N=27) were submitted twice to environmental challenges (challenge 1 and 2, 20 days in-between) composed of social (training), visual (mobile toy car) and auditory (air blast) stimuli. Cortisol levels decreased back to the baseline after the second challenge. The behavioral observations showed that: these MWD were more active, and presented less stereotypic behaviors (pacing, manipulation of the environment) during both visual challenges, whereas half low posture was observed during the first but not during the second visual challenge.The present study shows that this group of MWD still has an adaptation capacity to an environmental challenge (return to baseline of the cortisol levels, a higher posture during the second than at the first challenge). These results are encouraging and indicate that the dogs might have a diminished welfare (i.e. stereotypic behaviors), but are not chronically stressed. (C) 2007 Elsevier Inc. All rights reserved.
