1. Start by introducing the dog to other dogs in a controlled environment. If possible, start with a calm, friendly dog, and then gradually introduce more active or energetic dogs.
2. Give the dog plenty of treats and positive reinforcement when it behaves calmly around other dogs.
3. Avoid punishing the dog for being scared, as this may make the fear worse.
4. Take the dog on regular walks and expose it to other dogs in a positive way.
5. Socialize the dog with other dogs in a safe, supervised setting.
6. If the dog is still scared, seek help from a professional animal behaviorist.
