My advice is to force fetch. It is something I do with all my bird dogs. How advanced you go beyond FF is a seperate question. FF gives you a clear line of communication with your dog regarding retrieving. In other words, after force fetch you have a means to address a refusal to retrieve that your dog clearly understands. It is also the foundation that most advanced retriever trainers build on. I recommend you purchase The Danny Farmer/Judy Aycock DVD. They are both legendary retriever trainers. Danny Farmer is in Anderson TX., and Judy Aycock is in Sanger TX. Both are in easy driving distance of Ovilla, if you need help with their program. In my experience FF gives clarity and structure to both dog and handler regarding retrieving. After saying that, with some dogs more than others the retrieving desire needs to be nurtured and cultivated. There are also dogs that lack the natural retrieving desire and it's probably not worth the trouble with those
These people of whom Smokey Speaks are at the TOP of this list. I would see if you could work out something with Danny Farmer. Back in the late 80's when I was running all the Hunt Tests with my 1st Lab, Force Fetch was what got her through to a Master Title. My dog had Candlewood and Trumarc blood, she was VERY "hot" without help from a Pro Trainer, Gary Johnson, this would have never happened. Ed Aycock a Vet in Lewisville was my vet. He is a master and as Smokey says His Wife Judy is magic.
Get with a Pro trainer at least on Force Fetch. It is hard and NOT FUN. To be dome correctly, the dog will be subject to PAIN/REWARD. emphasis on PAIN. Like I say it's not fun to do or watch but it is required for any field work where you want your dog under control when the are out of your reach (all the time)
Also, remember, NOBODY wants to hunt with a dog which is not trained WELL. An uncontrolled dog will ruin the hunt for everyone. And you will be hoarse from screaming at her all day.
