Scary dog story

Something brushed up against my foot and my surprise turned to horror as I looked down and saw a cute little puppy. I decided to take it home with me. But as i was walking home the little puppy's skin came and it wasn't a puppy anymore it was a adult dog. I ran home as fast as i can and hid under my bed. The dog had sharp teeth. Then suddenly the dog was in my room. Ahhhhhhhhhhhhhhhhhhhhhhh . what had happened we dont know.
