Just Googling for Sally Jaffe, it doesn't appear that she's a bad person. She has a good history of dog training, and made a terrible mistake that day. Of course, nothing excuses the injuries caused to the victim, and it's sad all the way around.
Here's a photo of Sally Jaffe comforting the 70 year old victim.
It's really too bad this whole unfortunate event happened. It puts negative attention on our dogshows, which are mostly wonderful family events that include LOTS of active seniors showing and judging. There is so much bad press and anti-dog legislation out there from the Dems and stories like this just add fuel to their fire. We raise and show Beagles which are a very gentle breed therefore I am always reminding my son (8) that not all breeds are as loving and tolerant as ours and I keep him on a very short leash at the dog shows
