导致狗狗喜欢挖洞的主要原因有：第一、狗狗的筑巢行为，长期流浪的狗狗为了有一个休息的地方而挖洞；第二、狗狗因爪子有汗腺分布，所以通过挖Cave the cave to leave your own smell; third, the stray dog digs the hole to hide the food, hide the things that are not finished, wait for the hungry before eating, and avoid being snatched by other dogs; fourth, the dog digging the hole simply I just want to play.
