You think... You've made up a scenario where this was a happy go lucky dog who was just bounding around like Beethoven. It very easily could have been a very aggressive dog who was no where near under the control of a 12 year old or the parents, even if the cops could afford the time for her to catch up to it before it attacked them.

It just depends on what you want to imagine.

The bottom line is that the dog did not attack them unless you consider an approaching dog an "attacking" dog. So there's no indication that the dog was vicious.

It just depends on what you want to imagine.

And you have imagined there's a vicious dog here.
