I love Dawn's advice! It's your call whether to crate him or not. I'm not sure I would, but I would probably not do the Trick-or-Treat thing at all (but I'm anti-social). Another option is to put a note on the door, disconnect the doorbell, turn out all the lights and pretend you don't do Halloween.
I might put a note saying, "Halloween is against our religion. Please respectfully move along." or something like that. I refuse to be blackmailed by anyone. We don't do Halloween. Haven't for many years! It's not about religion, but we just don't do holidays. I have sat in the living room and watched people knock on the door and looked right at them and shook my head. LOL They just go away. We've never had any negative repercussions.
But if you want to hand out candy, I'd gate the dog into a far room with noise and sit on the porch.
*Now everybody knows how weird I really am* LOL
