Halloween // What should me and my dog be for Halloween?

I know I’m early, but I just got a new dog in November so I thought I could be something with him for Halloween because, every year for Halloween me and my “friends” try to be something matching for Halloween, but when it comes close to the 31st everybody bails out and I am the one that always does it. So I started to think if me and my dog should be something and I really can’t think of anything could you guys help?
