I guess two things: it seems like a common thing around here that people won't stutter when they're by themselves/with a dog. Personally I've never felt that, my stutter stays pretty constant regardless if I'm talking to myself or someone else. Second, I wouldn't include a "solution" to a problem we don't really have a solution for yet. If this video is to raise awareness, then people watching it might go, "huh, it *would* suck to stutter. Good thing all they have to do is stop worrying so much and they'll be healed!" I kind of like the dog, but not as a secret human. I like him as a dog, as someone that will sit and listen and let you talk and not judge you. This portrays to any non-stutterers that all we really want out of them is patience. I would juxtapose the dog with the reactions of the humans the stutterer interacts with. Maybe a waiter snickers at him when he orders food, stuff like that. More than anything else, a video about raising awareness needs to portray our internal frustrations. Convey our emotions through the video, not the solution.
