I've not been around many malinois, but I know people who handle them and they all say that, "they are alot of dog."

Sounds like he was on edge during the situation and maybe the child moved very quickly or maybe the dog didn't like the child's posture and the dog's instinct just kicked on into over drive.
Maybe it was just too much at one time. However, you would think that a dog like that would not have made it as far as "custom's dog" in the first place.
