Just follow the routine above more intensely. There are some good training tapes out for puppies. One is excellent. Dr. Ian Dunbar's Puppy Training. I recommend you get it.
Puppies are easy to train.
Make it fun. Reward, do not punish. Consistency and follow through If you are not willing or do not have the time to make a pup do something, do not ask them to do it. Make it fun. When you are going to initiate ANY training make it sound like fun.
