Oh that reminds me of something. In the early 90's there was a kennel importing/training GSD's. Anyway, the proprieter sold a dog to a lady, who was shortly thereafter bit very badly. She sued the kennel & the jist of the whole thing was that he had told her to never take the dog out without a muzzle. Now obviously, you don't sell a dog like that to an inexperienced person. I guess this is an example of the bad extreme. I don't remeber what the outcome of the whole thing was.
