I'd be curious to know what you are trying to accomplish? Why are you interested in K9 training? I know you've talked a lot about becoming a breeder, so is that why you're interested? Are you looking to test the merits of your dog?
If so, then what I would strongly recommend you do is talk to people at your local Schutzhund clubs and find out where their dogs came from. Find a breeder who has a reputation for producing IPO dogs, and talk to them. Let them know about your interest in breeding and ask them if they wouldn't mind spending some time with you so you can learn from them, possibly even establish a mentor relationship.
One of the things I love about the GSD community is that good breeders want to teach in order to continue bettering the breed.
