搜救犬
犬具有高度发达的神经系统，有灵敏的嗅觉、非凡的听觉、敏锐的视觉等特点；犬的鼻子里有 2.2 亿个嗅觉细胞，是人嗅觉能力的 300 万倍左右，能嗅出数万种不同气味；听力是人的16 倍，能在复杂的环境中进行声音辨别；而且犬视觉发达，具有在微弱光线下视物的能力。
搜救犬除了利用犬上述特有的功能外，还对犬的服从性、注意力、耐久性等有很高的要求。搜救犬性情温顺、攻击性弱，同时工作热情高，能很快地适应工作环境，投入工作。搜救犬中比较常用的品种为德国牧羊犬、拉布拉多犬、金毛猎犬、史宾格犬等。
而经过严格训练的搜救犬，在各种灾难救援现场发挥了独特的作用，它能捕捉空气中弥漫的人体散发的一些细微气味并引导训导员接近人体的地方，同时能判定是否是幸存者，还是遇难者的遗体。因此，在地震、雪崩等各种灾难后帮助寻找和搜救失踪的受难者，搜救犬的作用更是无可替代。
