RE: german shorthair question
Depending what you are planning to do with him. If you are going to send him to a trainer, most like the dog to come when called, and also be used to being steaked out. This time of year I would do my best to build confidence, get him into some birds and see what he does. You do not have to kill birds over a pup there first year. If you are going to send himto a trainer, i would find one now and take hime in the spring or summer.
