Is there a dog at the end of silent hill2

Spoilers Yes there is. After beating the game once, an item appears in the game. Around the time of going into the park and meeting Maria for the first time, there is a dog house in a kennel like area. In the dog house is the dog key. At the very end of the game, you can enter the "Observation Room" using it, which is just down the hall from where you start the Dark Side of the Hotel. In the observation room is a Dog with headphones, and a funny ending.
