First off I am not a trainer... I have trained my dogs. I have never met anyone from Duck Buster Kennels yet. I have a few questions for you though too. What goals or expectations did you discuss with DBK prior to dropping the dog off? How old is your dog? Did the dog have any training before he got to DBK? (IE...sit, stay, heel, place, force fetch, hold, steady to shot or command) This may sound harsh but.... Have you considered maybe this dog isn't going to be exactly what you want? It does happen. Not all dogs can be Lee Mac or Drake....
If a dog is at the trainer you will be charged yes. Not all trainers have time to hunt. Did you ask or did DBK say anything about when he would start hunting? I would think you may have been able to plan for such an event. That way your dog wouldn't be at the trainer sitting in the kennel. Does DBK only have 1 trainer to work the dogs? Maybe while in Canada, someone else was suppose to be working your dog.
Handling does not take years to teach. Unless maybe the dog has Down Syndrome. But a trainer will never tell an owner their dog is untrainable. What did he mean by Master Level? Was he prepping your dog for a Master Hunter Test? Was that discussed prior to giving him your dog?
Dropping birds is easily fixed with Force breaking and teaching HOLD. Unless the dog doesn't like feathers in its mouth. That would take longer to fix.
I think a little better/more communication would have really helped this situation.
