Guilty Dog ?

Which one is the guilty party? 別以為狗狗沒有罪惡感​ !
Anyone who thinks a dog does not remember or does not feel guilt has not lived with a dog. Just look at the expressions on the faces of these three dogs when they are asked the same question at the same time ...... same tone of voice. They are all being asked the same question. The guilty one cannot help but feel guilty while the others have no look of guilt whatsoever.
