The image shows an animal lying motionless on its side. If you look close enough, you can see in white, the words "shut up", "dumb dog" as well as "stupid". With that being said, the animal is most likely a dog. Also, seeing that it is motionless, the dog is probably dead. The words "stupid" and "dumb" might be used when an individual is angry at someone. When anger escalates, it can lead to murder. Maybe that is what is being illustrated, a scene of murder. The dog is most likely the victim, and the 'killer' may well be the dog's owner. The owner might have been angry with the dog, thus the words "shut up", "dumb dog" and "stupid". Perhaps the dog did something in the past, therefore angering the owner which eventually led to murder of the dog by the owner.
