I don't quite agree with that :\ I'm not 'all natural' with dog training but I think with proper training and exercise for all dogs you shouldn't have to put your dogs in a situation where you would have to use a crop or switch to physically get them off of each other. Especially if you are there to supervise you should be able to read dog behaviors well enough to stop a potential fight before it even begins.
I agree the dogs should know the 'leader' is the owner, but there are other ways of doing that without a crop. Proper training and discipline go a long ways.
