I have trained our pup myself. I do use an e-collar once the pup has the basics but truthfully responding to the "tone" function is what I quickly work toward. That keeps things as quiet as possible in the field. I can hunt for an entire day and not have to say (or whistle) a word. I do not train competition dogs like Blaine does so our training methods are very different.
As far as dew claws, Blaine explained why he doesn't have them removed, but honestly it concerns me. Our pup has already ripped one completely off. It regrew but dewclaws don't touch the ground so they have to be trimmed religiously. Blaine doesn't do things without reason, but we differ on dew claw removal. If it is of concern, talk to Blaine about it. Hunting in many areas in the West is in sandy soil. Your dogs claws won't wear off. They also will wear into very sharp points. I would plan to trim claws every 2-3:weeks to avoid injury.
My last thought, when I picked up our pup I spent a day with Blaine. It was well worth it. He had 15 or so dogs in his runs. Most places, when you walk in pandemonium breaks out. Not a bark, not a whine. Friendly, calm dogs mirroring their trainer.
