为了进一步确定在硬地面追踪训练中,分别以“物品”和“物证”作为标的物时受训犬追踪作业的表现差异,笔者跟踪和记录了两期培训班受训犬的表现。发现利用“物品”进行追踪训练的受训犬在兴奋性和把线情况的表现较利用“物证”进行追踪训练的受训犬要好,而在低头意识上,两者的结果确是相反的。 In order to further confirm the differences in the performance of trainee dogs when they were traced to hard ground using the “” and “physical evidence ” as the subject, the author tracked and recorded the performance of trained dogs in two training courses. It was found that dogs trained in tracing using “objects ” performed better in excitability and trait performance than trainees trained in tracing using “physical evidence ”, whereas in dumbfounding, the results of the two were indeed the opposite of.
