I am in the PNW and yes, I have a conformation bred Lab. My trainer has been in the game for decades. He has a more open-minded approach to training, I suppose. Working with some really great local obedience people who don't want to use force, he's developed some different ways of training. My Lab is a bit over two. I did not introduce him to birds until he was about 9 months then started working with him when he was a year. I went through one trainer that I just didn't care for in the end and started with another trainer last winter. Nothing is holding us back. Well, besides a very demanding job, work travel, being a single home-owner and the fact that my priority is obedience since it can be done at night and in any weather. We do what we can with the time we have.
I never said you'd teach all of those things you mentioned with clicker-training. I'm not saying you can't, I don't know. My dog was solid in obedience before he ever touched a bird. Of course, adding birds creates a serious distraction, but I also work with live flyers each time I have a lesson. In fact, Linus goes with my trainer to the pen to "pick" his bird (not really, but my trainer humors him) at nearly every lesson we have. So, I am able to train in realistic conditions on a fairly regular basis. I also do obedience training with distractions. For example, a down or sit stay with a Pomeranian running around the room or a ball bouncing or a treat dropping a few inches from the dog. This crosses over nicely to the field. We teach by setting the dog up for success, not allowing him to make mistakes, until it becomes a habit and the dog gains confidence. The initial training pond did not allow for cheating, the dog started off by going straight in, it became a habit, so he just does it. We added distractions, challenges, etc. slowly and built him up to an open pond. He knows no other way and more importantly he knows this is right as it has been reinforced the right way. Also, this dog has always been one to run straight out and over and through obstacles, water, brush, grass, etc. We've worked on go outs and directed retrieving in obedience since he was a pup, so we had a foundation there as well.
My experience has been different than yours as he has trained quickly using R+ methods. He shuts down using any other method. He is far ahead of the three dogs of the same age from my first field group, who are all field bred, but received very little -- if any -- obedience training prior to going into the field. They were all FF'ed and were just starting CC when I left the trainer and the group. Who knows, they may end up to be brilliant with time and maturity.
People talk about tools in toolboxes, but, like compulsion training, there is not just one way to teach R+ training exercises. It is not always with a clicker. It is not always with food. I did not reinforce the retrieve with a clicker, my dog was born knowing how and loving to retrieve. There are several R+ ways to teach a dog an exercise and it is always geared toward the dog's temperament. If anyone wants to know more, instead of questioning me as I am not a pro, there are people you can talk to who train in this fashion who may be able to share experiences and advice. There are R+ classes and books you can read, and I have found that R+ trainers are pretty good at sitting down with you to problem solve and if you talk to enough people, you can get all kinds of good ideas to try. My obedience trainer is at the MH level with her dog using R+ and she works with the same field trainer that I do, so I guess I am fortunate to have the local knowledge and support. There are also R+ training forums where people share information and experiences. If a person is only interested in poking holes in proven theories, especially without information and experience to back you up, that is an issue, but those smarter than I am will not humor that discussion.
At one time, no one thought you could do obedience and never correct your dog, but more and more people are doing it very successfully. Though Janice Gunn is not R+ in the field, she no longer corrects her dogs in obedience and has said she'll never go back. Denise Fenzi, not just in obedience, but she pioneered IPO using R+ methods, again, something that people thought could never be done. And yes, these women are pros, but that is where it all begins. Denise has brought an R+ field trainer to her team to teach foundation skills without the use of force. About 200 people have signed up for this very first class and there was a huge amount of support for this class even among those who do not have retrievers. The R+ movement in field is just beginning and is getting serious traction. I'm excited to see how it turns out.
