I'm not sure if he's actually owned by these people, he's just there all the time. He's not wearing a collar and appeared to be half starved. I've been tempted to knock on the door and ask if he's their's, but afraid if I draw attention to myself I may not be able to sneak food to him, if he is. He walks like he hurts, and his fur is matty and dull. I feel so bad for him.
