For now lot's of play and small amounts of play training.  Sounds like you are on the right track.  As far as hyper, well that depends allot on your dog and his breeding.  Did you see the mom and dad?  They would be a good indicator of his drive and excitement level.  My oldest shorthair is a couch potato until she is in the field.  She still knows how to pace herself though and only turns it on when she needs to.  My middle girl goes non- stop outside, but once she turned 2 YO she mellowed out quite a bit inside.  She still has Crazy Halo (her name is Halo) moments though.  My youngest is 7 months and goes non-stop.  He has real high drive in the field and has had since he was a pup. Halo and my pup, Ringo, have the same mom, but different dads.

You do have the teething to look forward to from 4 - 6 months, so get lots of chew toys.  You will need them.

The only challenge I have ever faced with training (and I am talking about training to show in the obedience ring) in GSPs (my gang) is they will get bored really quickly with training.  So I keep training sessions really short and fun.  If I get a good response to an exercise we quit, even if it is the first try.  I also mix in allot of play, and often do wacky things during training so they never know what to expect and have to pay attention. Whether you are going to do formal obedience or not, I think the formula of short, sweet and fun is good for these guys.

Welcome to the forum, and it is a requirement of membership that you have to post pictures .  Have fun and good luck with your new pup.  I think you will find GSPs are amazing dogs. Many on the forum will say (myself included) you can never have just one.

you should look for a navhda chapter or akc club in your area there you should find some one to help teach you to train you pupp
