It would depend on the individual dog and its training as to whether the girl could hold the dog back. Our neighbours dog is very well trained and will obey/not run or chase. When they take her camping, she is always leashed/tied up per rules, but at home she is loose when the owners are outside. The dog will sit at the side of the road and watch other dogs, cats going by and not move, even if the other dogs are making aggressive moves toward her.
It is training and confidence in your child and dog about there abilities. Others, well!!!
