I agree training to field trial skill levels is unnecessary for hunting dogs. I also agree those that train and develop superior dogs help to ensure that meat hunters have the best package available.
I was looking for that. Several said the same thing. However, in the retriever world, as far as how FC dogs are perceived, I'm not so sure that is the norm (the available package "thing").
Gary as for your question on training....my expectations on drills, marks and blinds are that the dog will eventually be able to deal with them......correctly in a manner which will 1) satisfy my expectations, 2)approach excellence and 2) impress judges.
When I go hunting I expect my dog to 1) do as well as we can with those circumstances which appear to be a bit different, 2) feel like I'm am just as strict (which I am not), 3) reveal areas we need to work on and 4) not have to impress a single judge.
