Does the dog know that it has done something wrong?

When a dog knows that it has done something wrong, it usually senses it from its owner's emotions. If the owner scolds the dog, the dog will know that he has done something wrong, because the dog can know the emotion expressed by the owner from the tone and volume of the owner's voice and the owner's actions. Dogs will make movements such as curling their tails, lowering their heads, and exposing their bellies to beg their owners for forgiveness.
