在日本，大约 30% 参加毒品侦查犬训练计划的犬只成功完成训练。为了阐明与毒品检测犬的能力相关的因素并开发评估工具，我们评估了 197 只候选犬的基因型和行为特征。训练开始后两周内评估行为特征，包括一般活动、服从训练、注意力、情感需求、对狗的攻击性、焦虑和对目标的兴趣。这些评级的主成分分析产生了两个成分：工作欲望和注意力分散度。工作欲望与成功完成培训显着相关（P < 0.001）。由于93.3%的通过训练的狗和53.3%的未通过训练的狗的工作欲望得分为45或更高，因此通过采用这个分界点，我们将能够在训练3个月之前拒绝大约一半的不合适的狗。我们还调查了与人类人格维度相关的四个基因的八个多态性区域。基因型与狗是否通过无关，但注意力分散与 5HTT 单倍型之间存在弱关系（P < 0.05）。 (C) 2006 Elsevier B.V. 保留所有权利。
In Japan, approximately 30% of dogs that enter training programs to become drug detection dogs successfully complete training. To clarify factors related to the aptitude of drug detection dogs and develop an assessment tool, we evaluated genotypes and behavioural traits of 197 candidate dogs. The behavioural traits were evaluated within 2 weeks from the start of training and included general activity, obedience training, concentration, affection demand, aggression toward dogs, anxiety, and interest in target. Principal components analysis of these ratings yielded two components: Desire for Work and Distractibility. Desire for Work was significantly related to successful completion of training (P < 0.001). Since 93.3% of dogs that passed training and 53.3% of the dogs that failed training had Desire for Work scores of 45 or higher, we will be able to reject about half of inappropriate dogs before 3 months of training by adopting this cut-off point. We also surveyed eight polymorphic regions of four genes that have been related to human personality dimensions. Genotypes were not related to whether dogs passed, but there was a weak relationship between Distractibility and a 5HTT haplotype (P < 0.05). (C) 2006 Elsevier B.V. All rights reserved.
