A Grateful Dog

Last weekend my father drove his car into the town.All of a sudden,he met with a stray dog lying on the road.My father stopped and picked it up,only to find it was seriously wounded.He examined it silently and found part of its one ear was gone.He put it in his car and looked after it carefully.To his joy,it returned to health soon.Since then,the dog has been always following around.It always sits beside my father when he drives a long way to deliver goods.That brings much pleasure on the dull way.I think that perhaps the dog is showing thanks to my father for saving its life in its own way.
