The key to training him is patience. You have to realize that even up to about 3 months. All most pups wanna do is play. However the most important thing that most people over look is the schedule. It has to be constant. Once you get a feel for his "bathroom breaks", set a time with however many intervals you're able to provide. Everyday commands should be taught with no distractions. Tv, radio, other people or dogs around, etc., sit- stay- no -outside etc., once your dog starts doing the commands, reward him with a treat. And only use those treats for training sessions. After the repetition sets in it will become habit. Good luck!
I think you should first focus on house training and working on the basic commands like sit, stay, come and down. Reward him with treats each time he answers to a command correctly so that he learns that he is doing something right. Also, when he goes to the bathroom outside or on a wee-wee pad (wherever you want him/her to go to the bathroom), then show that you are excited and happy that he did his business in the right place. You can also sign your dog up for an obedience class where you can learn how to train your dog. Visit a pet store near you to see if they hold any obedience classes.
