Remember that your dog is a dog, he doesn't come prewired to know "not to pull on leash". A dog is restrained ALL day, confined to a house or yard, finally when the dog is outside, they get excited! Be patient, don't expect perfection right away, use humane training tools that can make your life easier and reward good behaviour. Loose leash walking isn't a difficult behaviour to teach, it's difficult for owners because it takes time to train.
