Abstract: Objective The guide dogs’ working status of Labrador retrievers was evaluated by complex environment test, to explored the relationship between exploratory and working status of Labrador retrievers. Method Using the improved DMA test method of Swedish Working Dog Association, 41 Labrador dogs from Dalian training base of Chinese guide dogs were evaluated, and the dogs were divided into groups according to the score of exploratory behavior. Design a test method for complex environment, score the working state of guide dogs under different environmental stimulation conditions, analyze whether there are differences in the working state scores of different exploratory guide dogs in complex environment, and explore the relationship between exploratory and guide dogs’ working state. Result There were significant differences in the working state scores of the three groups of seeing-eye dogs under the stimulation of novelty objects (P<0. 05) , and there were significant differences in the working state scores of seeing-eye dogs with different genders under the stimulation of lighting and sound in complex environment (P < 0. 05) . Conclusion The working state of dogs with high exploratory ability is less affected when facing novelty objects. Under the condition of light and sound stimulation, the working state of male dogs is less affected. Exploratory males are more adaptable to complex environments.

摘要： 目的 通过复杂环境测试评估拉布拉多犬在复杂环境条件下的工作状态,探究拉布拉多犬的探索性与工作状态之间的关系。 方法 使用经过改良的瑞典工作犬协会的 DMA 测试方法,评估来自中国导盲犬大连培训基地的 41 只拉布拉多犬,将犬按照探索性行为得分高低分组。 设计复杂环境测试方法,对测试中不同环境刺激条件下导盲犬的工作状态进行评分,分析探索性不同的导盲犬在复杂环境中的工作状态得分是否有差异,探究探索性与导盲犬工作状态之间的关系。 结果 探索性不同的 3 组导盲犬在新奇物体刺激条件下的工作状态得分存在显著差异(P<0. 05) ,性别不同的导盲犬在复杂环境中灯光音响刺激下的工作状态得分存在显著差异 ( P < 0. 05) 。结论 探索性高的犬在面对新奇物体时工作状态受影响的程度较小。在灯光音响刺激条件下,雄性犬工作状态受影响的程度较小。 探索性高的雄性更能适应复杂环境。
