Brainstorming help, please: What job could my new dog have?

I may be getting a puppy – still thinking. If I do, I want to work with him. Ideally, I would love to work with him in a way that is beneficial to other people. If I can make some money while “on the job”, that would be great. Volunteer work interests me, too, though!

What do you suggest? Any new, interesting ideas? Old favourites? I’d want to read up on the topic beforehand, as well as choosing the puppy accordingly.

I know my plans can’t be finalized without the pup’s “consent”, of course.
