| Early socialization is extremely important, the first 12 weeks along with genetics largely determine personality and temperament. At 3 years, you dog's personality is largely determined, and will be hard to change. More exposure to other people may help. Do you ever wear a baseball cap? Maybe if he sees you in one, he will fear men in them less. Recruit some little girls to help. Arm them with treats. Treats don't need to be fancy, even some of his regular kibble should do. Make a show of being glad to see the girls, and let them give him the treats. It may be better to start by dropping or tossing them to him. German shepherd are not as food motivated as many dog, but treats work with most dogs. Same thing with old people. Work out different things for each situation. The combination of showing you trust them, and them giving him treats may work. Your attitude toward the people is very important. He can read your emotions. Try to be happy and calm. Most mean, nasty dogs are owned by mean, nasty people. |
