The objective of the study was to assess the effects of a dog-appeasing pheromone (DAP) collar in reducing sound-induced fear and anxiety in a laboratory model of thunderstorm simulation. Twenty-four beagle dogs naïve to the current test were divided into two treatment groups (DAP and placebo) balanced on their fear score in response to a thunderstorm recording. Each group was then exposed to two additional thunderstorm simulation tests on consecutive days. Dogs were video-assessed by a trained observer on a 6-point scale for active, passive and global fear and anxiety (combined). Both global and active fear and anxiety scores were significantly improved during and following thunder compared with placebo on both test days. DAP significantly decreased global fear and anxiety across 'during' and 'post' thunder times when compared with baseline. There was no significant improvement in the placebo group from baseline on the test days. In addition, the DAP group showed significantly greater use of the hide box at any time with increased exposure compared with the placebo group. The DAP collar reduced the scores of fear and anxiety, and increased hide use in response to a thunder recording, possibly by counteracting noise-related increased reactivity.
该研究的目的是评估犬安抚信息素（DAP）项圈在雷暴模拟实验室模型中减轻声音诱发的恐惧和焦虑方面的效果。将24只对当前测试无经验的比格犬根据其对雷暴录音的恐惧评分分为两个治疗组（DAP组和安慰剂组）。然后，每组在连续两天内接受另外两次雷暴模拟测试。由一名经过培训的观察员以6分制对犬在主动、被动和整体恐惧与焦虑（综合）方面进行视频评估。在两个测试日，与安慰剂组相比，在雷暴期间及之后，整体、主动恐惧与焦虑评分均有显著改善。与基线相比，DAP在雷暴“期间”和“之后”显著降低了整体恐惧与焦虑。在测试日，安慰剂组与基线相比无显著改善。此外，与安慰剂组相比，DAP组在任何时候随着暴露增加对藏身处的使用显著更多。DAP项圈降低了恐惧和焦虑评分，并增加了对雷暴录音的藏身处使用，可能是通过抵消与噪音相关的反应性增加来实现的。
