I spend about 3-4 hours a week total in training with my boy. He's higher drive/energy but when the weather gets cold we don't do as much. Plus the days are short and its hard to train in the dark. We trial in AKC obedience, rally, and starting to do agility. I'm working towards his CDX right now and the end goal is a UDX. I'd do Schutzhund, but that's an extreme time commitment, for me its nice to have the ability to miss a training session if something else pops up.
