Rex: My Action Adventure Story part 3

Hey, I'm back, my next adventure is more scary then usual. It started last Halloween while my owners were out trick or treating. I was in my bedroom with T and then I heard a noise coming from behind me. The noise, though I didn't notice it at the time, was a voice. Then I turned around and saw the Headless Horseman riding on horseback. I asked "Why would you want my head? I mean, I'm just a dog." Even though he had no head I thought I heard him say something like"I need your help finding a missing dog." So I wondered what kind of dog could he be looking for. Then I thought that Cerberus might have escaped the underworld. Then I thought that he might mean a wienerdog. So I looked around for a gigantic, three headed dog or a regular sized wienerdog. Soon I saw two types of dogs one of them was a giant, three headed dog the other was a skinny little dog. I howled at the wienerdog. Then the Headless Horseman came to me and I think he said "Good dog." Then the Headless Horseman, Cerberus and the wienerdog disappeared. I went back to my room and went to sleep. To be continued.
