I'm also doubting that it was just that that caused the dog to "go over the edge".
I agree. If the dog was not prone to unpredictable, violent behavior in the first place, jerking and holding a leash is not going to cause it in one day. I also can't imagine why anyone with any knowledge about dogs would think that the "trainer"-of-the-day at Petco was a good, knowledgeable source of information concerning an unknown, aggressive animal. Please.


Someone told me the most dog bites are from....Cocker Spaniels!
I don't know about the most, but cockers are certainly up there in the list of top biters. They were, I think, number three when our shelter in Colorado compiled statistics of dog bites. Interestingly enough, numbers one and two on the list were labs and golden retreivers. Why were cockers, labs and goldens the top three biters? Because they were the top three most popular dogs in the county ... there were simply more of them. My cocker hates kids, always has. She has never bitten anyone, but she has never been friendly, either, and I don't trust her with kids. Cockers ... like so many breeds ... are victims of their own popularity. They were lovely animals at one time, until puppy mills and back yard breeders bred all the good sense and good temperment right out of them. It's a terrible shame.
