I've seen helpers hiss too, usually in the blind. I think that a hiss coupled with a good stare and posture makes the helper seem more threatening and draws attention up to the face? Maybe it helps the helper feel more threatening and create the right body posture?
I also make noises when I snatch the ball, I'm not sure that it has any real purpose other than me making sound effects for my actions? You know...like little boys that make racecar noises when they run? It helps me feel like I'm doing something more exciting, so I present a more exciting picture to the dog? Thinking out loud...
I don't know I'll have to ask.
