Training is ongoing, not just an $800 session pack. A 4 month old pup should not start PP training until he has matured mentally some.
I would look and go to different training clubs in your area and see what you like and make sure the people know what they are doing(do not send your dog away for training/do this yourself!). You can start SchH anytime, but do not rush your pup...especially in the defensive stuff. SchH has 3 phases, tracking, obedience and protection.
Protection doesn't start until the pup is more mature/ so you can start the other two now. Bitework/tugging is not a good time to start now~ teething stage starts around 4 months, won't be done til about 7 months. So that should be put on hold til teeth are in.
If the dog has'it', he will do fine in either venue and starting later is better mentally, especially for a male pup. Work on confidence building/track/article indication/even retrieves can be started now if you think you want to do SchH. Find a good club!
I like Sch type training to start, because you do more obedience/control work on the dog. Control is key whichever you decide to do.
