And to add to Choochi, in my breed, Labrador Retrievers, in some European countries a dog cannot achieve a top title in conformation without a title in a hunting venue as well. Don't ask me for details, it's just something from a European on another board. That's not the case here in N. America but I do see more conformation type Labs competing in field events.
Somewhat ironically, back to the spaniel needing protection in cold water (that was what started all this wasn't it?) a lot of field Labs have a thin, single coat, are leaner and rangier and truly cannot withstand the cold, particularly the cold water, as well as their heavier double coated, bulkier show bred companions. My trainer put vests on his field bred dogs for hunting in cold water in November. In Labs I see just as much corruption of the breed in the field breeding as in the show breeding. Because, as my field trainer put it to me, field trials themselves are not what you'd want the dog to do in actual hunting.
