Ya field training. I want to be able to hunt and Target shoot with him/her.
I would contact your local GR clubs for breeder referalls. Unless you're a really avid hunter or field trialer, you probably don't need a strong field pedigree, imo. Just a breeder who follows the standard. Our pet bred boy whom was our first dog has impressed even a semi professional duck hunting guide.
By school, do you mean field training or basic obedience? We keep everything light and fun until 6+ months. The obedience is the main priority until their brains start to mature. I've trained my own hunting dog and I've sent one to a pro. I'll probably send out to a pro again for basics, just because I don't always have the time. I'm not entirely comfortable with doing my own force fetch training. My husband did that portion with our home trained dog after working and learning from our experienced pro trainer.
