Thanks for your comments.
I keep wanting to say that bringing his service dog is a protected ADA accommodation, but his situation is more complex than just having seizures isn't it?
Indeed, it is. His episodes aren't only dangerous for him but also for everyone around him. Actually, they are only dangerous for others since he's invulnerable. But the situation is also complex from a dramatic point of view. If I solve Clark's dilemma, Houdini loses his purpose. I already feel bad for that poor dog. Not quite sure yet how to solve this problem.
