I live about a mile away from the Hobart shelter....This whole situation is sad, but mostly because it could have been AVOIDED. The dog really didn't "turn without warning," I don't think--it sounds like there was a person who misguidedly thought she was helping or saving the bullie by concealing the truth about her history and her propensity to bite. I don't have all the "facts," obviously, but I'm just at a loss as to how any rescue dog could have been behind on immunizations and then let out uncrated and mingling with the public at an event. The main thing is to take care of your health and well-being. I am so sorry to hear that this happened, to you and to the dog who was put into a situation where she was so likely to re-offend .
