Why does a shadow form behind the dog when a light shines on it?

A shadow forms behind the dog when a light shines on it because the light cannot pass through the dog. Instead, the light is blocked by the dog, creating a region of darkness behind it where the light cannot reach. This creates the shadow that we see.
