The next important thing is leash-training. The earlier your pup accepts the leash and collar, the easier the rest of his training will be. Your pup should quickly accept the leash and follow you with ease.
(NOTE: never let your pup bite the leash! Correct this action with a firm NO and, if the pup persists, accompany the NO with a flick on the nose)
Once you pup gets to the point where he is not afraid of the leash and looks forward to his walks, you can teach him to not pull you; this is a major step in his overall training, though it may not be wise to try this until the pup is at least 3-4 months old. Allowing your pup [once he's older] to lead you on walks is telling him that he is alpha and gets to choose the direction and pace of your travel. In wild wolf packs, the alpha always leads the pack on hunts. A lower-ranking member who tries to surge ahead will be harshly reprimanded.
If your wolfdog tries to yank ahead of you, a firm tug on the leash accompanied with a negative sound (whatever sound or noise you use to get your pup's attention if he's getting ready to snatch a donut or sandwich from the table) should get his attention.
Using "The Sound": Use the same noise every time; make sure you're consistent. He will come to associate that sound with something bad that he's doing, and he will stop and look at you. You can then tell him what he was doing [or about to do] was wrong, and then tell him NO. Using this sound on walks when he tries to pull ahead will slow him down and he will return to your side at the pace of your travel.
Once he gets used to 'The Sound', it will be easy to make corrections before he does something bad. Wolfdogs are highly intelligent, and as your pup gets older, he will be able to recognize the tone of your voice and what it means in each situation. And you will be able to predict by his facial expression or posture alone whether he's about to do something bad or not.
