This is actually very pertinent to me, as Pan nailed my leg hard (not enough to break skin, but enough to cause a large nasty bruise and scraping) yesterday. This isn't normal behaviour for her, but a combination of many factors resulted in a dog who got hyper-stimulated and lost her mind briefly.
While I agree with most of the article, I also think that when you deal with certain breeds, you have to be aware that getting bit is a very real and likely possibility. Yes, it is possible to train for a more calm and thinking state of mind (where Pan is 99% of the time), but be ready for some war wounds in the process.
