I left to go out for the night while my roommate stayed home to dog sit and stay home for the night. About an hour after I left I was notified by my roommate that he found the front door wide open and the dog no where to be found. He has the ability to open a door if he really tries and manages the to stand up and pull the lever, although has never done it before. My roommate feels terrible, and I'll be sleepless until I find my best friend. He is deaf, so it makes it even harder to go call for him and find him. I drove around for hours without any luck, so I'm resorting to other options to find him.
