The update video here, including interview with the mother, 3 daughters and a niece, and video of the dogs apparently with owners.

Note: there appears to be more attention by media for several reasons here, not the least being: Victims and perps all female, vid of dogs with handlers available, victims all muslims well spoken, injuries minor.
The girls appear to have multiple scratches, but do not appear to have anything that will scar badly. The mother is probably in worse shape, as she stepped in between the dogs and the girls.
