Bassman,
Re:
"I would think you would have established who the boss is long before the dog is old enough to be ff through all of the obediance training the dog should have gone through."
As I stated earlier, FF/CR is not just about the act of a dog picking something up. But, for sake of argument, let's say that this is all there is to FF/CR:
First, do not assume that obedience training is completely finished by the "normal" age that FF/CR is traditionally done, about 6+ months. As dogs mature, they will occasionally test the pack leader's authority. Even the best dogs do this. It is a normal part of growing up. It could happen at 1 year, 1 1/2, 2, whatever. If it hasn't happened with your dog yet, it will. Let's say that at some point, your dog decides to change the pickup order and switches to another bird. If you have not FF/CR, what recourse do you have? Or let's say he is going through one of these testing events and decides to stop halfway back from a retrieve and spit the bird out and stare at you. Don't think that your dog is not capable of this type of behavior. If you have not FF/CR, what recourse do you have? Etc...
For further sake of argument, think of it this way; if you have not FF/CR you have not completed the obedience training process. Think of FF/CR as obedience training involving one of the most important of all canine organs; the mouth. This is why I previously mentioned the importance of the dogs mouth. Until you have instilled the "obedience of the mouth", you do not have reliable control over what is arguably his most important organ, and therefor you do not have reliable control of the dog. You do not have the type of WORKing relationship with the retriever that will get you through those really tough situations.
Having said that, FF/CR is not just about "obedience of the mouth". As mentioned previously, it is much more than that.
Something to think about: I do retrieving demonstrations with Jack for various organizations and events. One of the things I do is demonstrate the end result of FF/CR. I will throw some bumpers on the ground and walk Jack through, telling him to fetch this one, and telling him to leave that one, etc. I hold a bumper at head height and command fetch. Jack leaps up and grabs it. I push and pull on the bumper while it is in his mouth and he does not let go. I command give and he lets go. I have him fetch and hold various objects; a box of shells, a heeling stick, a remote launcher transmitter, different size and shape bumpers, etc. I finish by holding out a McDonald's hamburger. I command fetch and he grabs and holds it. I wait a little while until he is drooling all over. I command give and he lets go of it. After a few more repetitions, I tell him OK and he gets to eat it. I have to tell you something. While the above is going on, Jack is wagging his tail the whole time. He is a happy dog. He knows what is expected of him, and he knows how to meet my expectations. He knows his role, performs with excellence and I respect and trust him for it. He believe he also respects and trusts me.
That is not to say that Jack or I are perfect. We both mess up, but the WORKing relationship we have forged, gets us through in the end...as a team of two.
