多兵种犬狗的机智勇敢历来被人称道,它灵敏的嗅觉,能透地3米,区别200万种物质和不同浓度的气味,并有惊人的记忆力。1812年,意大利米兰的一只狗随主人加入拿破仑远征的队伍,到达俄国明斯克后,狗与主人失散了。时隔1年多后,这只狗安全无恙地回到米兰主人家里。这中间有2800公里的路程,并须通过白雪皑皑的阿尔卑斯山,其间的艰难险阻可想而知。 The multi-breed dog has always been witty and courageous, its sensitive smell, can penetrate 3 meters, the difference between 2000000 kinds of substances and different concentrations of odors, and astonishing memory. In 1812, a dog in Milan, Italy, joined the Napoleon's expedition with the host. After arriving in Minsk, Russia, the dog was separated from the owner. After a lapse of more than a year, the dog returned home safely to Milan. This is the middle of 2,800 kilometers and must pass through the snow-capped Alps, during which the difficulties and dangers can be imagined.
