This sort of behaviour is known as a "pit and run".
This is in Venice, California, and the photo of the woman and the dog is quite clear. The woman appears to be a white female between the ages of 26-35 with dirty blonde hair pulled back, no makeup. Glasses. HWP and sitting down in the street with her pit bull in her lap. Clear photo, identifiable, and the dog is a dark grey pit bull with a white chest and white front paws.
Post her pic here.
Craven Desires Blogspot. What a depth this world has sunken to.
Probably would make more sense to post it on NextDoor than on here.
Have you informed the local police? Her next walk with the dog should be problematic.
For crying out loud. How difficult could it be to identify the person? She apparently - obviously - was jogging with the dog dressed the way she is.. Report it to the police in the area and they will question neighbors in the neighborhood and someone will ID her. What a waste of time - a phone call to the police should have been the first act.
Dark grey color in a pit bull is referred to as “blue”. The least you could do is get the nomenclature correct in your campaign against the breed.
