I have been bitten three times in my life. Once as a child I was mauled badly and spent time in the hospital. Twice as an adult I've been bitten. So I have a healthy respect for the power of a large aggressive dog. Sure I may be biased or "doggy prejudiced" but it is what it is and I carried the scars to back up my feelings. For the record all three times I was attacked was by a GSD. I don't like them either.
