I’ve never heard of anyone not training tracking until the time leading up to the trial. It’s probably the toughest part of the whole thing, and that’s where I’ve seen most dogs fail.
If you’re just talking about “testing” a dog, and truly coming at a dog that has never had a human attack it before and seeing how it reacts…well, most dogs aren’t going to fight. If it’s a young dog, it’s highly unlikely the dog has the confidence to take on a 180+ lbs. human. If it’s an older dog, that has never had any sort of introduction to bite work, it was probably taught bite inhibition and to respect humans, so it’s unlikely that it will attack a human. This is almost the same thing as people expecting their untrained GSD to protect them if they do get attacked…most GSDs won’t.
Depends on the club…but I’ve been to a few that do focus a lot more on protection. At the end of the day, obedience and tracking are easily done on your own time and unless you are a true beginner, most people will do that outside of club time because that’s the only time you get to work with a helper.
Anyways…when was the last time you took a test that you didn’t study/prepare for?
