Now that is just ridiculous! A child has been scarred for life by a dog and nothing was done? The bite must be legally reported when your daughter received medical treatment. The owner needed to be held accountable, the dog quarantined at least in it's home for 10 days, and at least a "mark" on that dog's permanent record so that when it bites another person or two, it must be labeled as an aggressive dog, wear the special tags and a muzzle when taken out.
And I'm serious about the rally on Capital Hill. Get enough people, each holding a snake, and maybe someone will actually notice that none of the thousands are in danger of being killed. Get an equal number of people there, each with a dog on a leash and see just how non-dangerous dogs are. And don't even think about doing it with cats!
