Have you informed the local police? Her next walk with the dog should be problematic.
I am not in Venice, CA. Nor is Craven Desires my blog. I have no connection with the item, blog, or person posting this.
Sometimes it is more fulfilling to attempt to right one wrong than inform many of a life-changing disaster.
If the dog and its owner can be located, it may eliminate the necessity for a series of very expensive (USD$10,000 I believe) and painful rabies shots for the victim, already suffering from pain, fear, trauma, and a broken wrist.
