As long as you have good genetics, which I'm sure you do; the best thing you can do for your dog right now is socialization. This is what makes the difference between a good hunting dog and a great hunting dog. You have plenty of time to work on obedience. What you need to be doing right now is exposing him to as much as possible, especially kids. I never start any obedience until the dog is at least six months old. Good manners need to start right away, but let the pup be a pup now and it will pay huge dividends down the line.
