I believe it fully, that there is no such thing as a dog who's without faults, but as has been said already some show more than others. As well, some aren't actually ever "seen", I've read before about dogs who were said to be the most perfect examples of their breed ever, structure instinct and temperament, but then found they couldn't reproduce, oh well. I do strive to find all my own dogs faults, I know all of Enda's, and I even find them in the altered boys too, just for fun mostly, but educational fun none the less.
