Italian explorer Columbus， who discovered Americafor Spain in 1492， believed that for fighting Indiansone dog was worth fifty soldiers.So when he advancedinto America he took a pack of two hundred-and-fifty-pound mastiffs with him.

In one industrious battle in 1495，these mastiffsleaped upon and disembowelled more than a hundredIndians apiece.

This figure was reported by anobserver of the fight， Bartolotne de los Casas， who，realising that it was difficult to credit， went on toexpIain that the dogs were used to disembowelling deerand boars， and so found the soft and hairless skin ofIndians quite easy to bite into.

意大利探險家哥倫布1492年為西班牙發(fā)現(xiàn)了美洲。他認(rèn)為，和印第安人作戰(zhàn)，一只狗抵得上50個士兵，所以，深入美洲時，他帶了一群250磅重的獒犬。

1495年，那些獒犬在一場激戰(zhàn)中，撲向印第安人，把他們內(nèi)臟挖出來，每只殺死100人以上。這數(shù)字是目睹戰(zhàn)事者巴托洛梅·德拉斯卡薩斯說的。他知道難以令人置信，特意解釋說，那些獒犬習(xí)慣了挖鹿、野豬等的內(nèi)臟，要咬破印第安人柔軟無毛的皮膚，自然不會困難。
