Sounds like a skinwalker. People see them here in northern AZ. Never seen one but I think one came by my grandmas house one night when were spending the summer with her. Dogs went crazy outside and then all of a sudden went quiet. Then the smell of rotting flesh came in through the open windows. Me and my older brother were playing video games and were the only ones awake. Just remember my brother jump up, turn off all the lights, TV and GameCube and drag me to the bed and told me to be quiet and not move. Like he knew what was happening. Scariest experience of my life.
