As mentioned, don't really think of any type of formal training until you can get the dog to listen and respond correctly to your obedience commands. Your main focus should be setting the tone for the dog as far as it's boundaries and getting it to listen to you when and how it's told too. Lots of time to get the rest done. Way too many dogs get started before they should and they lose interest due to things not being any fun and them being overstressed. You have to remeber that dogs have maturity levels just like kids...some start sooner than others, but for the most part, you want common obedience commands down pat and the dog to know who's in charge before you start asking it too much too soon.
