Using yummy treats as a training aid may help to lessen your dog's fear of strangers or other dogs when out on walks.

Walk your dog before meals so he's hungry. At the first sight of a stranger, act jolly and relaxed, and give your dog a treat. Your goal is to help the dog see a stranger as your reason to pull out the treats and be happy.

As your dog begins to show anxiety or fear, stop giving the treats freely. Ask your dog for a calmer, more controlled behavior such as a "sit," and reward him with treats.

Over time, repeat these techniques as you decrease the distance between you and the stranger in tiny stages.
