Why do dogs bury bones?
Dogs berry bones long got from the prehistory. Dog s did it then, because not always they had food, so they berries the food in the dirt, and when ever they were hungry, they got back to that place to dig it out. The dog don t really have a reason to do this, but some dogs just feel that if they owner eats, then they should to, so they watch their hidden food until they ll be hungry enough to dig it out.
