there are chips on both pieces. the open mouth dog is missing a tooth and the closed mouth dog is missing a toe, both statues measure 4" tall, 4" wide and 2" long

there are holes in the bottom end and holes in the nose of both and the mouth of the open mouth dog, I tired putting incense in the back hole and the smoke would come out the nose and the mouth but the stick would go out fairly quickly. I do not know the purposes of the holes.
