You only have to put the dog on it’s side in a very aggressive case but that probably isn’t the case here. But you SHOULD disagree with the growling and barking behavior whether it is a firm NO or SHH or a tap on the side or make them sit.

The dog was probably fearful of the hooded figure and the child was probably making eye contact with the dog which made her anxious/scared and caused her to growl, bark. Usually just making them sit / laydown is enough to snap them out of it.
