My thought is to look at it from the dogs point of view. You bring dog in to honor,dog on Line is sent for the retrieve. Your dog breaks makes it say 40 yards and is corrected with "here-nick-here" . Your dog complies. You set up the same situation but are watching for your dog to break honor. You give correction at 20 yards "Here-nick-here",the honor dog thinks it's a forty yard limit before it must comply. It freaks out flopping like a fish out of water for a correction that it clearly didn't understand. "Sometimes you must think like a dog to train like a pro " Delmar Smith. SLOW DOWN you've only got one dog to train . The "Pro" must fit the dog in his program box or send it down the road and if it's your dog you better hope there is a fix if the "pro has tried to fit your dog ,a square peg in a round hole. You need to train the dog you have not the one that fits in the program box.It's clear to me the dog understands pressure and how to turn in off if applied correctly for actions it understands. I would evaluate where it is in it's maturity -spend some time reviewing CC recall , whistle sit,debolting and walking fetch . With walking fetch I lay out my ladder of bumpers 10 yards apart and require the dog to walk at heal on a rope with the collar and pick up bumpers in a random order,every other bumper ,every third bumper. The object is to have the dog ONLY fetch a bumper when given the command. I even walk over bumpers with the dog at heal . This helps greatly greatly steadiness.
